035262a18d MIPS DSPr2: Work around various 'make test' errors
Referring to #408, this commit #ifdefs DSPr2 SIMD functions that only
work on little endian processors, and it completely excludes
jsimd_h2v1_downsample_dspr2() and jsimd_h2v2_downsample_dspr2().  The
latter two functions fail with the TJBench tiling regression tests, most
likely because the implementation of the functions predates those tests.

044c22e12f Test: Honor CMAKE_CROSSCOMPILING_EMULATOR variable
This CMake variable is intended to define a wrapper program for
executing cross-compiled executables.  However, CTest doesn't use
CMAKE_CROSSCOMPILING_EMULATOR, because it isn't obvious which tests
should be executed with the wrapper and which tests are scripts that
don't need it.  This commit manually prepends
${CMAKE_CROSSCOMPILING_EMULATOR} to all unit test command lines that
execute a program built by the libjpeg-turbo build system.  Thus, one
can set CMAKE_CROSSCOMPILING_EMULATOR in a CMake toolchain file to (for
instance) "qemu-{architecture} {qemu_arguments}") in order to execute
all eligible unit tests using QEMU.

52291467e1 Travis: Use MacPorts instead of Homebrew
Homebrew tends to drop support for a macOS release the second that Apple
stops releasing security updates for it, and that makes HB difficult to
use with some of the Travis macOS images.  Furthermore, even on
supported macOS releases, HB sometimes tries to build GCC from source
even if a binary (bottle) is available.  Long story short, MacPorts just
generally has better backward compatibility.  MacPorts is also what I
personally use on the official libjpeg-turbo build machine.

c76f4a0826 Huffman enc.: Fix very rare local buffer overrun
... detected by ASan.  This is a similar issue to the issue that was
fixed with 402a715f82.  Apparently it is
possible to create a malformed JPEG image that exceeds the Huffman
encoder's 256-byte local buffer when attempting to losslessly tranform
the image.  That makes sense, given that it was necessary to extend the
Huffman decoder's local buffer to 512 bytes in order to handle all
pathological cases (refer to 0463f7c9aad060fcd56e98d025ce16185279e2bc.)

Since this issue affected only lossless transformation, a workflow that
isn't generally exposed to arbitrary data exploits, and since the
overrun did not overflow the stack (i.e. it did not result in a segfault
or other user-visible issue, and valgrind didn't even detect it), it did
not likely pose a security risk.

55de97207d AppVeyor: Use MinGW-builds instead of MSYS2 MinGW
... to avoid backward compatibility issues with GCC 4-6 MinGW
toolchains.  Apparently GCC 7+ MinGW toolchains introduce a link-time
dependency with internal MinGW CRT functions that are meant to provide
compatibility with Microsoft's Universal CRT (ucrt) library, but those
internal functions are not available in GCC 4-6 MinGW toolchains.  This
made it impossible to use the official builds of libjpeg.a and
libturbojpeg.a with GCC 4-6 MinGW toolchains (a fatal link error--
"undefined reference to '__imp___acrt_iob_func'"-- occurred.)

This problem was not immediately apparent after switching to the MSYS2
implementation of MinGW (d6d7b53968)
because, for a while, MSYS2 was still using GCC 5 and 6.

2a9e3bd743 TurboJPEG: Properly handle gigapixel images
Prevent several integer overflow issues and subsequent segfaults that
occurred when attempting to compress or decompress gigapixel images with
the TurboJPEG API:

- Modify tjBufSize(), tjBufSizeYUV2(), and tjPlaneSizeYUV() to avoid
  integer overflow when computing the return values and to return an
  error if such an overflow is unavoidable.
- Modify tjunittest to validate the above.
- Modify tjCompress2(), tjEncodeYUVPlanes(), tjDecompress2(), and
  tjDecodeYUVPlanes() to avoid integer overflow when computing the row
  pointers in the 64-bit TurboJPEG C API.
- Modify TJBench (both C and Java versions) to avoid overflowing the
  size argument to malloc()/new and to fail gracefully if such an
  overflow is unavoidable.

In general, this allows gigapixel images to be accommodated by the
64-bit TurboJPEG C API when using automatic JPEG buffer (re)allocation.
Such images cannot currently be accommodated without automatic JPEG
buffer (re)allocation, due to the fact that tjAlloc() accepts a 32-bit
integer argument (oops.)  Such images cannot be accommodated in the
TurboJPEG Java API due to the fact that Java always uses a signed 32-bit
integer as an array index.

509c2680aa Use bias pattern for 4:4:0 (h1v2) fancy upsampling
This commit modifies h1v2_fancy_upsample() so that it uses an ordered
dither pattern, similar to that of h2v1_fancy_upsample(), rounding up or
down the result for alternate pixels rather than always rounding down.
This ensures that the decompression error pattern for a 4:4:0 JPEG image
will be similar to the rotated decompression error pattern for a 4:2:2
JPEG image.  Thus, the final result will be similar regardless of
whether a 4:2:2 JPEG image is rotated or transposed before or after
decompression.

c8e52741fd Travis: Use xcode8.3 image
xcode7.3 is based on El Capitan, which is EOL, and Homebrew no longer
provides El Cap bottles (pre-compiled binaries.)  Thus, Homebrew was
trying to build GCC 5, YASM, and the other packages we need from source,
which caused the Mac CI builds to time out.  I tried goading Homebrew
into installing GCC 5.5.0_2 and YASM 1.3.0_1, which still have El Cap
bottles available, by using the URLs of those specific versions of the
formulae (from the Homebrew GitHub repository) as package names.  This
failed, however, because 'brew bundle' converted the URLs to all
lowercase.  I then tried explicitly installing the old formulae by using
'brew install' with the aforementioned URLs (bypassing the Travis
Homebrew addon), but Homebrew still tried to build all of the
dependencies from source.

Upgrading to Xcode 8.3.x necessitated regression testing the performance
on iOS, but that proved less of a pain than figuring out how to install
all of the old Homebrew bottles we needed.  Also, this future-proofs the
CI builds against the inevitable discontinuation of the xcode7.3 image.

Note that Xcode 8.3.x improves iOS 64-bit decompression performance
significantly relative to Xcode 7.2.x or 7.3.x.  iOS 32-bit performance
unfortunately regresses by as much as 5%, but it can't be helped (32-bit
iOS apps are no longer supported on iOS 11+ anyhow, and the next major
release of libjpeg-turbo will remove support for them as well.)

aa9db61677 x86 SIMD: Check for CPUID leaf 07H before using
According to Intel's manual [1], "If a value entered for CPUID.EAX is
higher than the maximum input value for basic or extended function for
that processor then the data for the highest basic information leaf is
returned."

Right now, libjpeg-turbo doesn't first check that leaf 07H is supported
before attempting to use it, so the ostensible AVX2 bit (Bit 05) of the
CPUID result might actually be Bit 05 from a lower leaf.  That bit might
be set, even if the CPU doesn't support AVX2.

This commit modifies the x86 and x86-64 SIMD feature detection code so
that it first checks whether CPUID leaf 07H is supported before
attempting to use it to check for AVX2 instruction support.

DRC:
This commit should fix
https://bugzilla.mozilla.org/show_bug.cgi?id=1520760
However, I have not personally been able to reproduce that issue,
despite using a Nehalem (pre-AVX2) CPU on which the maximum CPUID leaf
has been limited via a BIOS setting.

d3a3a73f64 jdhuff.c: Silence UBSan signed int overflow error
Some pathological test images have been created that can cause s to
overflow or underflow the signed int data type during decompression.
This is technically undefined behavior according to the C spec, although
every modern implementation I'm aware of will treat the signed int as a
2's complement unsigned int, thus causing the value to wrap around to
INT_MIN if it exceeds INT_MAX.  This commit simply makes that behavior
explicit in order to shut up UBSan.  At least when building for x86-64
or i386 using Clang or GCC, this commit does not change the
compiler-generated assembly code at all.

The code that triggered this error has existed in the libjpeg code base
for at least 20 years (and probably much longer), so the fact that it
hasn't produced a user-visible problem in all of that time strongly
suggests that UBSan is being overly pedantic here.  But if someone can
cough up a platform that doesn't wrap around to INT_MIN when 1 is added
to INT_MAX, then I'll happily change my opinion.

b46af82cc1 ARMv7 NEON: #ifdef unused funcs/vars w/ -mfpu=neon
When simd/arm/jsimd.c is compiled with __ARM_NEON__ defined (which will
be the case if -mfpu=neon is passed to the compiler), the
parse_proc_cpuinfo() and check_feature() functions and the bufsize
variable are unused and thus need to be #ifdef'ed out in order to avoid
compiler warnings.  Note that the bufsize variable was already #ifdef'ed
out on Linux but not on Android due to lack of parentheses (&& takes
precedence over ||.)

4b67db4d9b rpm.spec.in: Fix doc packaging issues w/ RHEL 7+
On RHEL 7 and later (not sure exactly whether this is a product of the
newer RPM release or something distro-specific), macros are lazily
expanded, so we need to set _docdir using %global (which expands at
definition time) and prior to _prefix and _datarootdir (which affect
_defaultdocdir.)  Otherwise, _docdir is set to a subdirectory of
/opt/libjpeg-turbo/share/doc or /opt/libjpeg-turbo/doc.  The former
(which happens on RHEL 7) leads to incorrect documentation packaging
(the docs should be packaged under /usr/share/doc per Red Hat
standards), and the latter (which happens on RHEL 8) leads to an RPM
build error.

479501b07c TurboJPEG: Decompress 4:4:4 JPEGs with unusual SFs
Normally, 4:4:4 JPEGs have horizontal x vertical luminance & chrominance
sampling factors of 1x1.  However, it is technically legal to create
4:4:4 JPEGs with sampling factors of 2x1, 1x2, 3x1, or 1x3, since the
sums of the products of those sampling factors are still <= 10.  The
libjpeg API correctly decodes such images, so the TurboJPEG API should
as well.

the private key is still strongly encrypted by Travis, and we use a

This allows for specifying an executable suffix of .html with Emscripten
builds, which causes Emscripten to build standalone HTML versions of the
libjpeg-turbo test programs.

84893085cf README.ijg: Clarification regarding JPEG 2000/XR
The sentence:
"Indeed, one of the original reasons for developing this free software
was to help force convergence on common, interoperable format standards
for JPEG files."
might be seen to imply that JPEG 2000 and JPEG XR are not interoperable
with themselves, although it is certainly the case that those formats
are not interoperable with each other, nor with
ITU T.81 | ISO/IEC 10918.  They are also certainly not as common as
ITU T.81 | ISO/IEC 10918, and (as an example) popular web browsers will
not display JPEG 2000 files.

The sentence in question was originally referring to proprietary,
non-standard formats and was meant to provide historical context.
libjpeg was originally released prior to the adoption of JFIF as an
official standard, so it encouraged adoption of JFIF as a de facto
standard by providing, under a business-friendly free software license,
a library for reading and writing images in that format.

43e84cff1b tjLoadImage(): Fix FPE triggered by malformed BMP
In rdbmp.c, it is necessary to guard against 32-bit overflow/wraparound
when allocating the row buffer, because since BMP files have 32-bit
width and height fields, the value of biWidth can be up to 4294967295.
Specifically, if biWidth is 1073741824 and cinfo->input_components = 4,
then the samplesperrow argument in alloc_sarray() would wrap around to
0, and a division by zero error would occur at line 458 in jmemmgr.c.

If biWidth is set to a higher value, then samplesperrow would wrap
around to a small number, which would likely cause a buffer overflow
(this has not been tested or verified.)

This change is proposed to enable cases where this library and it's CMakeLists.txt are included in other projects/CMakeLists.txt files as a dependency via the add_subdirectory method, for example: add_subdirectory(mozjpeg). There are several reasons and workflows which "wrap" third party projects/builds using this method, including many enterprise build/devops pipelines.

This change will have no effect on users building mozjpeg by itself as usual, it very simply enables the wrapping use cases.

bfc3ce3157 x86[-64] SIMD: Don't auto-generate jsimdcfg.inc
The old Un*x (autotools-based) build system always auto-generated this
file, but that behavior was more or less a relic of the days before the
libjpeg-turbo colorspace extensions were implemented.  The thinking was
that, if a particular developer wanted to change RGB_RED, RGB_GREEN,
RGB_BLUE, or RGB_PIXELSIZE in order to compress from/decompress to
different RGB pixel layouts, then the SIMD extensions should
automatically respond to those changes whenever they were made to
jmorecfg.h.  The modern reality is that changing RGB_* is no longer
necessary because of the libjpeg-turbo colorspace extensions, and
changing any of the other constants in jsimdcfg.inc can't be done
without making deeper modifications to the SIMD extensions.  In general,
we treat RGB_* as a de facto, immutable part of the legacy libpjeg API.
Realistically, since the values of those constants have been the same in
every Un*x distribution released in the past 20-30 years, any software
that uses a system-supplied build of libjpeg must assume that those
constants will have default values.

Furthermore, even if it made sense to auto-generate jsimdcfg.inc, it was
never possible to do so on Windows, so it was always going to be
necessary to manually generate the Windows version of the file whenever
any of the constants changed.  This commit introduces a new custom CMake
target called "jsimdcfg" that can be used, on Un*x platforms, to
generate jsimdcfg.inc on demand, although this should only be necessary
when introducing new x86 SIMD instructions or making other deep
modifications, such as SIMD acceleration for 12-bit JPEGs.

For those who may be wondering why we don't do the same thing for
win/jconfig.h.in, it's because performing all of the necessary CMake
checks to populate that file is very slow on Windows.

ed3c527386 README.ijg: Wordsmith per ISO/ITU-T suggestions
This commit merges the following paragraph from the latest libjpeg
release:
https://github.com/libjpeg-turbo/ijg/blob/jpeg-9c/README#L222-L229
which takes into account the fact that JFIF is now an official ISO/ITU-T
standard.  I also included the ISO/IEC document number for the JFIF spec
(jpeg-9c included only the ITU-T rec number.)

This commit also heavily wordsmiths the "FILE FORMAT WARS" section.
In jpeg-7 and later, this section has become somewhat impolitic,
referring to JPEG 2000 and JPEG XR as "faulty technologies" and
"momentary mistakes."  The original intent of this section, which was
introduced in jpeg-5 and refined in jpeg-6
(https://github.com/libjpeg-turbo/ijg/blob/jpeg-5/README#L317-L338,
https://github.com/libjpeg-turbo/ijg/blob/jpeg-6b/README#L335-L367)
was to highlight the problem of JPEG file format divergence that existed
in the 1990s prior to the adoption of JFIF as an official ISO/ITU-T
standard.  That problem is fortunately no longer a problem, thanks in
part to the existence of libjpeg.  I have attempted to preserve Tom's
intent of using this section to describe which file formats the code is
compatible with and why it isn't compatible with some file formats
bearing the name "JPEG."  Such modifications always put our project in a
very awkward position, because we are not the IJG and do not claim to
be, but it is still necessary for us to modify the IJG README file from
time to time to eliminate obsolete information while attempting to
remain as neutral as possible.

51f94caba1 Build: Use Colin Plumb's public domain MD5 code
... instead of the RSA code, the license for which contains an
advertising clause.  It is strongly believed that the RSA advertising
clause is innocuous, because:

- A clarification from RSA
  (http://www.ietf.org/ietf-ftp/IPR/RSA-MD-all), published in 2000,
  stated:

  "Implementations of these message-digest algorithms, including
  implementations derived from the reference C code in RFC-1319,
  RFC-1320, and RFC-1321, may be made, used, and sold without license
  from RSA for any purpose."

  Referring to the opinion from Fedora's legal team
  (https://fedoraproject.org/wiki/Licensing:FAQ?rd=Licensing/FAQ#What_about_the_RSA_license_on_their_MD5_implementation.3F_Isn.27t_that_GPL-incompatible.3F),
  this means that md5.c and md5.h, which were derived from the original
  RFC 1321 reference code (http://www.faqs.org/rfcs/rfc1321.html), can
  be used without the RSA license.

- In the context of libjpeg-turbo, RSA's MD5 code was used only in the
  build/test system.  It was not part of the libjpeg-turbo binary
  distribution, and thus the only "material mentioning or referencing"
  the MD5 code was the libjpeg-turbo source code, which-- by virtue of
  including RSA's original copyright headers-- properly attributed the
  code as required under the RSA license.

However, in light of the open source community's tendency to have
knee-jerk reactions to stuff like this, it would've been necessary to
include the above explanation in our source tree in order to head off
potential FUD, and a simple fix is always better than a complex
explanation.

This commit also assigns the 3-clause BSD license to my modifications of
the MD5 code.  This license is the same one used by md5cmp and other
parts of the build system.

c80ddef7a4 Build: Fix rpath in iOS shared libraries
When attempting to configure an iOS/ARM build with Xcode 7.2 and CMake
2.8.12, I got the following errors:

CMake Error at CMakeLists.txt:560 (add_library):
  Attempting to use MACOSX_RPATH without CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG
  being set.  This could be because you are using a Mac OS X version less
  than 10.5 or because CMake's platform configuration is corrupt.
(x 3)

CMake Error at sharedlib/CMakeLists.txt:38 (add_library):
  Attempting to use MACOSX_RPATH without CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG
  being set.  This could be because you are using a Mac OS X version less
  than 10.5 or because CMake's platform configuration is corrupt.
(x 3)

Upgrading to CMake 3.x (tried 3.0 and 3.1) got rid of the errors, but
the resulting shared libs still did not use @rpath as expected.  Note
also that CMake 3.x (at least the two versions I tested) does not
automatically set the MACOSX_RPATH property as claimed.  I could find
nothing in the release notes for later CMake releases to indicate that
either problem has been fixed.  What I did find was this little nugget
of code in the Darwin platform module:

f6b93fbf3a/Modules/Platform/Darwin.cmake (L33-L36)

This sets CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG="-Wl,-rpath," only if you
are running OS X 10.5 or later.  It makes no such check for iOS, perhaps
because shared libraries aren't much of a thing with iOS apps.  In any
event, this commit simply sets CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG if it
isn't set already, and that fixes all of the aforementioned problems.

Within the libjpeg API code, it seems to be more the convention than not

making it easy to automatically detect variations from our chosen

- Always use two-space indentation.  Never use tabs.
- Always use K&R-style conditional blocks.
- Always surround operators with spaces, except in raw assembly code.
- Always put a space after, but not before, a comma.
- Never put a space between type casts and variables/function calls.
- Never put a space between the function name and the argument list in
  function declarations and prototypes.
- Always surround braces ('{' and '}') with spaces.
- Always surround statements (if, for, else, catch, while, do, switch)
  with spaces.
- Always attach pointer symbols ('*' and '**') to the variable or
  function name.
- Always precede pointer symbols ('*' and '**') by a space in type
  casts.
- Use the MIN() macro from jpegint.h within the libjpeg and TurboJPEG
  API libraries (using min() from tjutil.h is still necessary for
  TJBench.)
- Where it makes sense (particularly in the TurboJPEG code), put a blank
  line after variable declaration blocks.
- Always separate statements in one-liners by two spaces.

The purpose of this was to ease maintenance on my part and also to make
it easier for contributors to figure out how to format patch
submissions.  This was admittedly confusing (even to me sometimes) when
we had 3 or 4 different style conventions in the same source tree.  The
new convention is more consistent with the formatting of other OSS code
bases.

This commit corrects deviations from the chosen formatting style in the
libjpeg API code and reformats the TurboJPEG API code such that it
conforms to the same standard.

NOTES:
- Although it is no longer necessary for the function name in function
  declarations to begin in Column 1 (this was historically necessary
  because of the ansi2knr utility, which allowed libjpeg to be built
  with non-ANSI compilers), we retain that formatting for the libjpeg
  code because it improves readability when using libjpeg's function
  attribute macros (GLOBAL(), etc.)
- This reformatting project was accomplished with the help of AStyle and
  Uncrustify, although neither was completely up to the task, and thus
  a great deal of manual tweaking was required.  Note to developers of
  code formatting utilities:  the libjpeg-turbo code base is an
  excellent test bed, because AFAICT, it breaks every single one of the
  utilities that are currently available.
- The legacy (MMX, SSE, 3DNow!) assembly code for i386 has been
  formatted to match the SSE2 code (refer to
  ff5685d5344273df321eb63a005eaae19d2496e3.)  I hadn't intended to
  bother with this, but the Loongson MMI implementation demonstrated
  that there is still academic value to the MMX implementation, as an
  algorithmic model for other 64-bit vector implementations.  Thus, it
  is desirable to improve its readability in the same manner as that of
  the SSE2 implementation.

0dd9a2c1fd Fix Win64 ABI conformance when using xmm8-xmm11
Referring to https://docs.microsoft.com/en-US/cpp/build/stack-usage:

"All memory beyond the current address of RSP is considered volatile:
The OS, or a debugger, may overwrite this memory during a user debug
session, or an interrupt handler.  Thus, RSP must always be set before
attempting to read or write values to a stack frame."

Basically, if-- under extremely rare circumstances-- a context swap were
to occur between saving the values of xmm8-xmm11 and setting the new
value of rsp, the O/S might not preserve that area of the stack.  In
general, libjpeg-turbo should not be using xmm8-xmm11 before or after
the call to jsimd_huff_encode_one_block_sse2(), so this is probably a
non-issue, but it's still a good idea to fix it.

c308d43416 jpeg_crop_scanlines: Handle gray images w/ samp!=1

773040f9d9 Fix lib state when skipping to end of 1-scan image
If jpeg_skip_scanlines() is used to skip to the end of a single-scan
image, then we need to change the library state such that subsequent
calls to jpeg_consume_input() will return JPEG_REACHED_EOI rather than
JPEG_SUSPENDED.  (NOTE: not necessary for multi-scan images, since the
scans are processed prior to any call to jpeg_skip_scanlines().)

Unless I miss my guess, using jpeg_skip_scanlines() in this manner
will prevent any markers at the end of the JPEG image from being
read, but I don't think there is any way around that without actually
reading the data, which would defeat the purpose of
jpeg_skip_scanlines().

Loading RGB image files into a grayscale buffer isn't a particularly

the compression process.  Also, the RGB2GRAY() macro was not producing
deterministic cross-platform results because of variations in the
round-off behavior of various floating point implementations, so
`tjunittest -bmp` was failing in i386 builds.

aa7459050d TurboJPEG C API: Add BMP/PPM load/save functions
The main justification for this is to provide new libjpeg-turbo users
with a quick & easy way of developing a complete JPEG
compression/decompression program without requiring them to build
libjpeg-turbo from source (which was necessary in order to use the
project-private bmp API) or to use external libraries.  These new
functions build upon significant enhancements to rdbmp.c, wrbmp.c,
rdppm.c, and wrppm.c which allow those engines to convert directly
between the native pixel format of the file and a pixel format
("colorspace" in libjpeg parlance) specified by the calling program.
rdbmp.c and wrbmp.c have also been modified such that the calling
program can choose to read or write image rows in the native (bottom-up)
order of the file format, thus eliminating the need to use an inversion
array.  tjLoadImage() and tjSaveImage() leverage these new underlying
features in order to significantly improve upon the performance of the
old bmp API.

Because these new functions cannot work without the libjpeg-turbo
colorspace extensions, the libjpeg-compatible code in turbojpeg.c has
been removed.  That code was only there to serve as an example of how
to use the TurboJPEG API on top of libjpeg, but more specific, buildable
examples now exist in the https://github.com/libjpeg-turbo/ijg
repository.

5bc43c7821 Further partial image decompression fixes
- Referring to 073b0e88a1 and #185, the
  reason why BMP and RLE didn't (and won't) work with partial image
  decompression is that the output engines for both formats maintain a
  whole-image buffer, which is used to reverse the order of scanlines.
  However, it was straightforward to add -crop support for GIF and
  Targa, which is useful for testing partial image decompression along
  with color quantization.
- Such testing reproduced a bug reported by Mozilla (refer to PR #182)
  whereby jpeg_skip_scanlines() would segfault if color quantization was
  enabled.  To fix this issue, read_and_discard_scanlines() now sets up
  a dummy quantize function in the same manner that it sets up a dummy
  color conversion function.

073b0e88a1 djpeg -crop: Exit gracefully with non-PPM formats
... and document that only PPM/PGM output images are supported with the
-crop option for the moment.

I investigated the possibility of supporting -crop with -bmp, but even
after resetting the buffer dimensions, I still kept getting virtual
array access errors.  It seems that doing this the "right way" would
require creating a re-initialization function for each image format's
destination manager.  I'm disinclined to do that right now, given that
this feature was Google's baby (developed as a prerequisite for
including libjpeg-turbo in Android), and the -crop option in djpeg is
intended only as an example of how to use the partial image
decompression API.  Real-world applications would need to handle this
in their own destination managers.

It would probably be possible to make this work with Targa by employing
a similar hack to the one we used with PPM, but Targa isn't popular
enough to bother.

_libdir.  However, newer versions of RPM (probably >= 4.6, since that

%{_prefix}/lib or %{_prefix}/lib64.  Thus, we need to explicitly

However, it isn't necessary to handle endianness in pure Java code such

c94531212f TJBench: Recover from non-fatal errors if possible
Previously, -stoponwarning only had an effect on the underlying
TurboJPEG C functions, but TJBench still aborted if a non-fatal error
occurred.  This commit modifies the C version of TJBench such that it
always recovers from a non-fatal error unless -stoponwarning is
specified.  Furthermore, the benchmark stores the details of the last
non-fatal error and does not print any subsequent non-fatal error
messages unless they differ from the last one.

Due to limitations in the Java API (specifically, the fact that it
cannot communicate errors, fatal or otherwise, to the calling program
without throwing a TJException), it was only possible to make
decompression operations fully recoverable within TJBench.  With other
operations, -stoponwarning still has an effect on the underlying C
library but has no effect at the Java level.

The Java API documentation has been amended to reflect that only certain
methods are truly recoverable, regardless of the state of
TJ.FLAG_STOPONWARNING.

b0971e47d7 TurboJPEG: Document xform issue w/ big marker data
If the source image for a transform operation has a lot of EXIF or ICC
data embedded in it, then it may cause the output image size to exceed
the worst-case size returned by tjBufSize() (because tjTransform()
transfers all markers to the output image.)  This is only a problem if
TJFLAG_NOREALLOC is passed to the function.  Since the TurboJPEG C API
doesn't require the destination image size to be set in this case, it
makes the documented assumption that the calling program has allocated
the destination buffer to exactly the size returned by tjBufSize().
Changing this assumption would change the API behavior and necessitate
a new function name (tjTransform2().)  At the moment, it's easier to
just document this as a known issue, since it's easy to work around in
the C API.

The Java API is unfortunately a different story, since it must always
use TJFLAG_NOREALLOC (because, when using the TurboJPEG Java API, all
buffers are allocated on the Java heap, and thus they can't be
reallocated by the C code.)  There is no easy way to work around this
without changing the C API as discussed above, because if the source
image contains large amounts of marker data, it's virtually impossible
to determine how big the output image will be.

1db1ce45da TJBench: Improve consistency of results
Given that libjpeg-turbo can often process hundreds of megapixels/second
on modern hardware, the default of one warmup iteration was essentially
meaningless.  Furthermore, the -warmup option was a bit clunky, since
it required some foreknowledge of how fast the benchmarks were going to
execute.

This commit introduces a 1-second warmup interval for each benchmark by
default, and the -warmup option has been retasked to control the length
of that interval.

da2a27ef05 Honor max_memory_to_use/JPEGMEM/-maxmemory
This re-introduces a feature of the obsolete system-specific libjpeg
memory managers-- namely the ability to limit the amount of main memory
used by the library during decompression or multi-pass compression.
This is mainly beneficial for two reasons:

- Works around a 2 GB limit in libFuzzer
- Allows security-sensitive applications to set a memory limit for the
  JPEG decoder so as to work around the progressive JPEG exploit
  (LJT-01-004) described here:
  http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf

This commit also removes obsolete documentation regarding the MS-DOS
memory manager (which itself was removed long ago) and changes the
documentation of the -maxmemory switch and JPEGMEM environment variable
to reflect the fact that backing stores are never used in libjpeg-turbo.

d4c41fe0da TurboJPEG: Fix potential memory leaks
Referring to https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=746,
it seems that the values of local buffer pointers in TurboJPEG API
functions aren't always preserved if longjmp() returns control to a
point prior to the allocation of the local buffers.  This is known to
be an issue with GCC 4.x and clang with -O1 and higher optimization
levels but not with GCC 5.x and later.  It is unknown why GCC 5.x and
6.x do not suffer from the issue, but possibly the local buffer pointers
are not allocated on the stack when using those more recent compilers.

In any case, this commit modifies the TurboJPEG API library code such
that the jump buffer is always updated after any local buffer pointers
are allocated but before any subsequent libjpeg API functions are
called.

44b2399a94 libjpeg API: Support reading/writing ICC profiles
This commit does the following:

-- Merges the two glueware functions (read_icc_profile() and
write_icc_profile()) from iccjpeg.c, which is contained in downstream
projects such as LCMS, Ghostscript, Mozilla, etc.  These functions were
originally intended for inclusion in libjpeg, but Tom Lane left the IJG
before that could be accomplished.  Since then, programs and libraries
that needed to embed/extract ICC profiles in JPEG files had to include
their own local copy of iccjpeg.c, which is suboptimal.

   -- The new functions were prefixed with jpeg_ and split into separate
   files for the compressor and decompressor, per the existing libjpeg
   coding standards.

   -- jpeg_write_icc_profile() was made slightly more fault-tolerant.
   It will now trigger a libjpeg error if it is called before
   jpeg_start_compress() or if it is passed NULL arguments.

   -- jpeg_read_icc_profile() was made slightly more fault-tolerant.
   It will now trigger a libjpeg error if it is called before
   jpeg_read_header() or if it is passed NULL arguments.  It will also
   now trigger libjpeg warnings if the ICC profile data is corrupt.

   -- The code comments have been wordsmithed.

   -- Note that the one-line setup_read_icc_profile() function was not
   included.  Instead, libjpeg.txt now documents the need to call
   jpeg_save_markers(cinfo, JPEG_APP0 + 2, 0xFFFF) prior to calling
   jpeg_read_header(), if jpeg_read_icc_profile() is to be used.

-- Adds documentation for the new functions to libjpeg.txt.

-- Adds an -icc switch to cjpeg and jpegtran that allows those programs
to embed an ICC profile in the JPEG files they generate.

-- Adds an -icc switch to djpeg that allows that program to extract an
ICC profile from a JPEG file while decompressing.

-- Adds appropriate unit tests for all of the above.

-- Bumps the SO_AGE of the libjpeg API library to indicate the presence
of new API functions.

6530203fdd Build: More GNUInstallDirs improvements
These improvements enable build systems to use GNUInstallDirs to define
custom directory variables.

- The set_dir() macro was renamed to GNUInstallDirs_set_install_dir(),
  in keeping with the module's established macro naming convention.

- Rather than detecting whether the prefix has changed, the new
  GNUInstallDirs_set_install_dir() macro instead examines whether the
  default for the variable in question has changed.  This allows for
  more flexibility, since build systems may decide to change the
  defaults based on factors other than the prefix.  It also enables the
  macro to work properly outside of the module.

- The module now performs directory variable substitution within the
  body of GNUInstallDirs_get_absolute_install_dir().

- The JAVADIR variable is no longer included in GNUInstallDirs.  That
  directory is not part of the GNU spec, and it turns out that various
  operating systems use different conventions for the location of Java
  classes.  Instead, the variable is now implemented in our build
  system as a demonstration of the aforementioned GNUInstallDirs
  enhancements.

d681fa7626 Build: Set install dirs in a more GNU-friendly way
This builds upon the existing GNUInstallDirs module in CMake but adds
the following features to that module:

- The ability to override the defaults for each install directory
  through a new set of variables (`CMAKE_INSTALL_DEFAULT_*DIR`).

  Before operating system vendors began shipping libjpeg-turbo, it was
  meant to be a run-time drop-in replacement for the system's
  distribution of libjpeg, so it has traditionally installed itself
  under /opt/libjpeg-turbo on Un*x systems by default.  On Windows, it
  has traditionally installed itself under %SystemDrive%\libjpeg-turbo*,
  which is not uncommon behavior for open source libraries (open source
  SDKs tend to install outside of the Program Files directory so as to
  avoid spaces in the directory name.)  At least in the case of Un*x,
  the install directory behavior is based somewhat on the Solaris
  standard, which requires all non-O/S packages to install their files
  under /opt/{package_name}.  I adopted that standard for VirtualGL and
  TurboVNC while working at Sun, because it allowed those packages to be
  located under the same directory on all platforms.  I adopted it for
  libjpeg-turbo because it ensured that our files would never conflict
  with the system's version of libjpeg.  Even though many Un*x
  distributions ship libjpeg-turbo these days, not all of them ship the
  TurboJPEG API library or the Java classes or even the latest version
  of the libjpeg API library, so there are still many cases in which it
  is desirable to install a separate version of libjpeg-turbo than the
  one installed by the system.  Furthermore, installing the files under
  /opt mimics the directory structure of our official binary packages,
  and it makes it very easy to uninstall libjpeg-turbo.

  For these reasons, our build system needs to be able to use
  non-GNU-compliant defaults for each install directory if
  `CMAKE_INSTALL_PREFIX` is set to the default value.

- For each directory variable, the module now detects changes to
  `CMAKE_INSTALL_PREFIX` and changes the directory variable accordingly,
  if the variable has not been changed by the user.

  This makes it easy to switch between our "official" directory
  structure and the GNU-compliant directory structure "on the fly"
  simply by changing `CMAKE_INSTALL_PREFIX`.  Also, this new mechanism
  eliminated the need for the crufty mechanism that previously did the
  same thing just for the library directory variable.

  How it should work:
  - If a dir variable is unset, then the module will set an internal
    property indicating that the dir variable was initialized to its
    default value.
  - If the dir variable ever diverges from its default value, then the
    internal property is cleared, and it cannot be set again without
    unsetting the dir variable.
  - If the install prefix changes, and if the internal property
    indicates that the dir variable is still set to its default value,
    and if the dir variable's value is not being manually changed at the
    same time that the install prefix is being changed, then the dir
    variable's value is automatically changed to the new default value
    for that variable (as determined by the new install prefix.)

- The directory variables are now always cached, regardless of whether
  they were set on the command line or not.  This ensures that they can
  easily be examined and modified after being set, regardless of how they
  were set.

  This was made possible by the introduction of the aforementioned
  `CMAKE_INSTALL_DEFAULT_*DIR` variables.

- Improved directory variable documentation (based on descriptions at
  https://www.gnu.org/prep/standards/html_node/Directory-Variables.html)

- The module now allows "<DATAROOTDIR>" to be used as a placeholder in
  relative directory variables.

  It is replaced "on the fly" with the actual path of
  `CMAKE_INSTALL_DATAROOTDIR`.

This should more closely mimic the behavior of the old autotools build
system while retaining our customizations to it, and it should retain
the behavior of the old CMake build system.

2af2fe42a3 Build: Clean up inline keyword detection
Strict C89-conformant compilers don't support the "inline" keyword, but

fcfc6c5eed Fix build when CFLAGS contains -std=c89 (or -ansi)
This is a subtle point, but AC_C_INLINE defines "inline" to be either
"inline", "__inline__", or "__inline".  The subsequent test for
"inline __attribute__((always_inline))" uses this definition.  The
attribute is irrespective of the inline keyword, so whereas
"__inline__ __attribute__((always_inline))" works under C89,
"inline __attribute__((always_inline))" doesn't, and defining INLINE to
the latter causes the build to fail.  The easiest way around this is
simply to define "inline" ahead of "INLINE" in jconfigint.h,
which causes the inline keyword detected by AC_C_INLINE to modify the
INLINE macro if necessary.

CMAKE_INSTALL_RPATH has to be set before the targets are defined (oops.)

The old autotools/libtool build system hard-coded the install name
directory of the OS X shared libraries to libdir, which meant that any
executable that linked against those libraries would also be hard-coded
to look for the libjpeg-turbo libraries in that directory.  @rpath makes
the OS X version of libjpeg-turbo behave like the Linux version, in the
sense that the executables under /opt/libjpeg-turbo/bin will
automatically pick up the libraries under /opt/libjpeg-turbo/lib* by
default, but other executables won't unless they are linked with -rpath.

cb88e5da80 ARM64 NEON: Fix another ABI conformance issue
Based on
98a5a9dc89
with wordsmithing by DRC.

In the AArch64 ABI, as in many others, it's forbidden to read/store data
below the stack pointer.  Some SIMD functions were doing just that
(stack pointer misuse) when trying to preserve callee-saved registers,
and this resulted in those registers being restored with incorrect
contents under certain circumstances.

This patch fixes that behavior, and callee-saved registers are now
stored above the stack pointer throughout the function call.  The patch
also removes register saving in places where it is unnecessary for this
ABI, or it makes use of unused scratch regiters instead of callee-saved
registers.

Fixes #97.  Closes #101.

077e5bb4e0 Fix out-of-bounds write in partial decomp. feature
Reported by Clang UBSan (refer to

This appears to be a legitimate bug introduced by
3ab68cf563.  Any component array, such
as first_MCU_col and last_MCU_col, should always be able to accommodate
MAX_COMPONENTS values.  The aforementioned test image had 8 components,
which was not enough to make the out-of-bounds write bust out of the
jpeg_decomp_master struct (and fortunately the memory after last_MCU_col
is an integer used as a boolean, so stomping on it will do nothing other
than change the decoder state.)  I crafted another special image that
has 10 components (the maximum allowable), but that was apparently not
enough to bust out of the allocated memory, either.  Thus, it is
posited that the security threat posed by this bug is either extremely
minimal or non-existent.

a09ba29a55 Fix unsigned int overflow in libjpeg memory mgr.
When attempting to decode a malformed JPEG image (refer to
https://bugzilla.mozilla.org/show_bug.cgi?id=1295044) with dimensions
61472 x 32800, the maximum_space variable within the
realize_virt_arrays() function will exceed the maximum value of a 32-bit
integer and will wrap around.  The memory manager subsequently fails
with an "Insufficient memory" error (case 4, in alloc_large()), so this
commit simply causes that error to be triggered earlier, before UBSan
has a chance to complain.

Note that this issue did not ever represent an exploitable security
threat, because the POSIX-based memory manager that we use doesn't ever
do anything meaningful with the value of maximum_space.
jpeg_mem_available() simply sets avail_mem = maximum_space, so the
subsequent behavior of the memory manager is the same regardless of
whether maximum_space is correct or not.  This commit simply removes a
UBSan warning in order to make it easier to detect actual security
issues.

8ce2c9119a TurboJPEG: Decomp. 4:2:2/4:4:0 JPEGs w/unusual SFs

technically legal to create 4:2:2 JPEGs with sampling factors of
2x2,1x2 and 4:4:0 JPEGs with sampling factors of 2x2,2x1, since the
sums of the products of those sampling factors (2x2 + 1x2 + 1x2 and
2x2 + 2x1 + 2x1) are still <= 10.  The libjpeg API correctly decodes
such images, so the TurboJPEG API should as well.

1120ff29a1 Fix AArch64 ABI conformance issue in SIMD code
In the AArch64 ABI, the high (unused) DWORD of a 32-bit argument's
register is undefined, so it was incorrect to use 64-bit
instructions to transfer a JDIMENSION argument in the 64-bit NEON SIMD
functions.  The code worked thus far only because the existing compiler
optimizers weren't smart enough to do anything else with the register in
question, so the upper 32 bits happened to be all zeroes.

The latest builds of Clang/LLVM have a smarter optimizer, and under
certain circumstances, it will attempt to load-combine adjacent 32-bit
integers from one of the libjpeg structures into a single 64-bit integer
and pass that 64-bit integer as a 32-bit argument to one of the SIMD
functions (which is allowed by the ABI, since the upper 32 bits of the
32-bit argument's register are undefined.)  This caused the
libjpeg-turbo regression tests to crash.

This patch tries to use the Wn registers whenever possible.  Otherwise,
it uses a zero-extend instruction to avoid using the upper 32 bits of
the 64-bit registers, which are not guaranteed to be valid for 32-bit
arguments.

This fixes crashes that would occur when attempting to use

RHEL 5.)  Even if the CPU supports AVX2, the O/S has to also support
saving/restoring YMM registers when switching contexts.

9055fb408d ARM/MIPS: Change the behavior of JSIMD_FORCE*
The JSIMD_FORCE* environment variables previously meant "force the use
of this instruction set if it is available but others are available as
well", but that did nothing on ARM platforms, since there is only ever
one instruction set available.  Since the ARM and MIPS CPU feature
detection code is less than bulletproof, and since there is only one
SIMD instruction set (currently) supported on those platforms, it makes
sense for the JSIMD_FORCE* environment variables on those platforms to
actually force the use of the SIMD instruction set, thus bypassing the
CPU feature detection code.

This addresses a concern raised in #88 whereby parsing /proc/cpuinfo
didn't work within a QEMU environment.  This at least provides a
workaround, allowing users to force-enable or force-disable SIMD
instructions for ARM and MIPS builds of libjpeg-turbo.

2.0.5
=====
### Significant changes relative to 2.0.4:
1. Worked around issues in the MIPS DSPr2 SIMD extensions that caused failures
in the libjpeg-turbo regression tests. Specifically, the
`jsimd_h2v1_downsample_dspr2()` and `jsimd_h2v2_downsample_dspr2()` functions
in the MIPS DSPr2 SIMD extensions are now disabled until/unless they can be
fixed, and other functions that are incompatible with big endian MIPS CPUs are
disabled when building libjpeg-turbo for such CPUs.
2. Fixed an oversight in the `TJCompressor.compress(int)` method in the
TurboJPEG Java API that caused an error ("java.lang.IllegalStateException: No
source image is associated with this instance") when attempting to use that
method to compress a YUV image.
3. Fixed an issue (CVE-2020-13790) in the PPM reader that caused a buffer
overrun in cjpeg, TJBench, or the `tjLoadImage()` function if one of the values
in a binary PPM/PGM input file exceeded the maximum value defined in the file's
header and that maximum value was less than 255. libjpeg-turbo 1.5.0 already
included a similar fix for binary PPM/PGM files with maximum values greater
than 255.
4. The TurboJPEG API library's global error handler, which is used in functions
such as `tjBufSize()` and `tjLoadImage()` that do not require a TurboJPEG
instance handle, is now thread-safe on platforms that support thread-local
storage.
2.0.4
=====
### Significant changes relative to 2.0.3:
1. Fixed a regression in the Windows packaging system (introduced by
2.0 beta1[2]) whereby, if both the 64-bit libjpeg-turbo SDK for GCC and the
64-bit libjpeg-turbo SDK for Visual C++ were installed on the same system, only
one of them could be uninstalled.
2. Fixed a signed integer overflow and subsequent segfault that occurred when
attempting to decompress images with more than 715827882 pixels using the
64-bit C version of TJBench.
3. Fixed out-of-bounds write in `tjDecompressToYUV2()` and
`tjDecompressToYUVPlanes()` (sometimes manifesting as a double free) that
occurred when attempting to decompress grayscale JPEG images that were
compressed with a sampling factor other than 1 (for instance, with
`cjpeg -grayscale -sample 2x2`).
4. Fixed a regression introduced by 2.0.2[5] that caused the TurboJPEG API to
incorrectly identify some JPEG images with unusual sampling factors as 4:4:4
JPEG images. This was known to cause a buffer overflow when attempting to
decompress some such images using `tjDecompressToYUV2()` or
`tjDecompressToYUVPlanes()`.
5. Fixed an issue, detected by ASan, whereby attempting to losslessly transform
a specially-crafted malformed JPEG image containing an extremely-high-frequency
coefficient block (junk image data that could never be generated by a
legitimate JPEG compressor) could cause the Huffman encoder's local buffer to
be overrun. (Refer to 1.4.0[9] and 1.4beta1[15].) Given that the buffer
overrun was fully contained within the stack and did not cause a segfault or
other user-visible errant behavior, and given that the lossless transformer
(unlike the decompressor) is not generally exposed to arbitrary data exploits,
this issue did not likely pose a security risk.
6. The ARM 64-bit (ARMv8) NEON SIMD assembly code now stores constants in a
separate read-only data section rather than in the text section, to support
execute-only memory layouts.
2.0.3
=====
### Significant changes relative to 2.0.2:
1. Fixed "using JNI after critical get" errors that occurred on Android
platforms when passing invalid arguments to certain methods in the TurboJPEG
Java API.
2. Fixed a regression in the SIMD feature detection code, introduced by
the AVX2 SIMD extensions (2.0 beta1[1]), that was known to cause an illegal
instruction exception, in rare cases, on CPUs that lack support for CPUID leaf
07H (or on which the maximum CPUID leaf has been limited by way of a BIOS
setting.)
3. The 4:4:0 (h1v2) fancy (smooth) chroma upsampling algorithm in the
decompressor now uses a similar bias pattern to that of the 4:2:2 (h2v1) fancy
chroma upsampling algorithm, rounding up or down the upsampled result for
alternate pixels rather than always rounding down. This ensures that,
regardless of whether a 4:2:2 JPEG image is rotated or transposed prior to
decompression (in the frequency domain) or after decompression (in the spatial
domain), the final image will be similar.
4. Fixed an integer overflow and subsequent segfault that occurred when
attempting to compress or decompress images with more than 1 billion pixels
using the TurboJPEG API.
5. Fixed a regression introduced by 2.0 beta1[15] whereby attempting to
generate a progressive JPEG image on an SSE2-capable CPU using a scan script
containing one or more scans with lengths divisible by 16 would result in an
error ("Missing Huffman code table entry") and an invalid JPEG image.
6. Fixed an issue whereby `tjDecodeYUV()` and `tjDecodeYUVPlanes()` would throw
an error ("Invalid progressive parameters") or a warning ("Inconsistent
progression sequence") if passed a TurboJPEG instance that was previously used
to decompress a progressive JPEG image.
2.0.2
=====
### Significant changes relative to 2.0.1:
1. Fixed a regression introduced by 2.0.1[5] that prevented a runtime search
path (rpath) from being embedded in the libjpeg-turbo shared libraries and
executables for macOS and iOS. This caused a fatal error of the form
"dyld: Library not loaded" when attempting to use one of the executables,
unless `DYLD_LIBRARY_PATH` was explicitly set to the location of the
libjpeg-turbo shared libraries.
2. Fixed an integer overflow and subsequent segfault (CVE-2018-20330) that
occurred when attempting to load a BMP file with more than 1 billion pixels
using the `tjLoadImage()` function.
3. Fixed a buffer overrun (CVE-2018-19664) that occurred when attempting to
decompress a specially-crafted malformed JPEG image to a 256-color BMP using
djpeg.
4. Fixed a floating point exception that occurred when attempting to
decompress a specially-crafted malformed JPEG image with a specified image
width or height of 0 using the C version of TJBench.
5. The TurboJPEG API will now decompress 4:4:4 JPEG images with 2x1, 1x2, 3x1,
or 1x3 luminance and chrominance sampling factors. This is a non-standard way
of specifying 1x subsampling (normally 4:4:4 JPEGs have 1x1 luminance and
chrominance sampling factors), but the JPEG format and the libjpeg API both
allow it.
6. Fixed a regression introduced by 2.0 beta1[7] that caused djpeg to generate
incorrect PPM images when used with the `-colors` option.
7. Fixed an issue whereby a static build of libjpeg-turbo (a build in which
`ENABLE_SHARED` is `0`) could not be installed using the Visual Studio IDE.
8. Fixed a severe performance issue in the Loongson MMI SIMD extensions that
occurred when compressing RGB images whose image rows were not 64-bit-aligned.
2.0.1
=====
### Significant changes relative to 2.0.0:
1. Fixed a regression introduced with the new CMake-based Un*x build system,
whereby jconfig.h could cause compiler warnings of the form
`"HAVE_*_H" redefined` if it was included by downstream Autotools-based
projects that used `AC_CHECK_HEADERS()` to check for the existence of locale.h,
stddef.h, or stdlib.h.
2. The `jsimd_quantize_float_dspr2()` and `jsimd_convsamp_float_dspr2()`
functions in the MIPS DSPr2 SIMD extensions are now disabled at compile time
if the soft float ABI is enabled. Those functions use instructions that are
incompatible with the soft float ABI.
3. Fixed a regression in the SIMD feature detection code, introduced by
the AVX2 SIMD extensions (2.0 beta1[1]), that caused libjpeg-turbo to crash on
Windows 7 if Service Pack 1 was not installed.
4. Fixed out-of-bounds read in cjpeg that occurred when attempting to compress
a specially-crafted malformed color-index (8-bit-per-sample) Targa file in
which some of the samples (color indices) exceeded the bounds of the Targa
file's color table.
5. Fixed an issue whereby installing a fully static build of libjpeg-turbo
(a build in which `CFLAGS` contains `-static` and `ENABLE_SHARED` is `0`) would
fail with "No valid ELF RPATH or RUNPATH entry exists in the file."
2.0.0
=====
### Significant changes relative to 2.0 beta1:
1. The TurboJPEG API can now decompress CMYK JPEG images that have subsampled M
and Y components (not to be confused with YCCK JPEG images, in which the C/M/Y
components have been transformed into luma and chroma.) Previously, an error
was generated ("Could not determine subsampling type for JPEG image") when such
an image was passed to `tjDecompressHeader3()`, `tjTransform()`,
`tjDecompressToYUVPlanes()`, `tjDecompressToYUV2()`, or the equivalent Java
methods.
2. Fixed an issue (CVE-2018-11813) whereby a specially-crafted malformed input
file (specifically, a file with a valid Targa header but incomplete pixel data)
would cause cjpeg to generate a JPEG file that was potentially thousands of
times larger than the input file. The Targa reader in cjpeg was not properly
detecting that the end of the input file had been reached prematurely, so after
all valid pixels had been read from the input, the reader injected dummy pixels
with values of 255 into the JPEG compressor until the number of pixels
specified in the Targa header had been compressed. The Targa reader in cjpeg
now behaves like the PPM reader and aborts compression if the end of the input
file is reached prematurely. Because this issue only affected cjpeg and not
the underlying library, and because it did not involve any out-of-bounds reads
or other exploitable behaviors, it was not believed to represent a security
threat.
3. Fixed an issue whereby the `tjLoadImage()` and `tjSaveImage()` functions
would produce a "Bogus message code" error message if the underlying bitmap and
PPM readers/writers threw an error that was specific to the readers/writers
(as opposed to a general libjpeg API error.)
4. Fixed an issue (CVE-2018-1152) whereby a specially-crafted malformed BMP
file, one in which the header specified an image width of 1073741824 pixels,
would trigger a floating point exception (division by zero) in the
`tjLoadImage()` function when attempting to load the BMP file into a
4-component image buffer.
5. Fixed an issue whereby certain combinations of calls to
`jpeg_skip_scanlines()` and `jpeg_read_scanlines()` could trigger an infinite
loop when decompressing progressive JPEG images that use vertical chroma
subsampling (for instance, 4:2:0 or 4:4:0.)
6. Fixed a segfault in `jpeg_skip_scanlines()` that occurred when decompressing
a 4:2:2 or 4:2:0 JPEG image using the merged (non-fancy) upsampling algorithms
(that is, when setting `cinfo.do_fancy_upsampling` to `FALSE`.)
7. The new CMake-based build system will now disable the MIPS DSPr2 SIMD
extensions if it detects that the compiler does not support DSPr2 instructions.
8. Fixed out-of-bounds read in cjpeg (CVE-2018-14498) that occurred when
attempting to compress a specially-crafted malformed color-index
(8-bit-per-sample) BMP file in which some of the samples (color indices)
exceeded the bounds of the BMP file's color table.
9. Fixed a signed integer overflow in the progressive Huffman decoder, detected
by the Clang and GCC undefined behavior sanitizers, that could be triggered by
attempting to decompress a specially-crafted malformed JPEG image. This issue
did not pose a security threat, but removing the warning made it easier to
detect actual security issues, should they arise in the future.
1.5.90 (2.0 beta1)
==================
### Significant changes relative to 1.5.3:
1. Added AVX2 SIMD implementations of the colorspace conversion, chroma
downsampling and upsampling, integer quantization and sample conversion, and
slow integer DCT/IDCT algorithms. When using the slow integer DCT/IDCT
algorithms on AVX2-equipped CPUs, the compression of RGB images is
approximately 13-36% (avg. 22%) faster (relative to libjpeg-turbo 1.5.x) with
64-bit code and 11-21% (avg. 17%) faster with 32-bit code, and the
decompression of RGB images is approximately 9-35% (avg. 17%) faster with
64-bit code and 7-17% (avg. 12%) faster with 32-bit code. (As tested on a
3 GHz Intel Core i7. Actual mileage may vary.)
2. Overhauled the build system to use CMake on all platforms, and removed the
autotools-based build system. This decision resulted from extensive
discussions within the libjpeg-turbo community. libjpeg-turbo traditionally
used CMake only for Windows builds, but there was an increasing amount of
demand to extend CMake support to other platforms. However, because of the
unique nature of our code base (the need to support different assemblers on
each platform, the need for Java support, etc.), providing dual build systems
as other OSS imaging libraries do (including libpng and libtiff) would have
created a maintenance burden. The use of CMake greatly simplifies some aspects
of our build system, owing to CMake's built-in support for various assemblers,
Java, and unit testing, as well as generally fewer quirks that have to be
worked around in order to implement our packaging system. Eliminating
autotools puts our project slightly at odds with the traditional practices of
the OSS community, since most "system libraries" tend to be built with
autotools, but it is believed that the benefits of this move outweigh the
risks. In addition to providing a unified build environment, switching to
CMake allows for the use of various build tools and IDEs that aren't supported
under autotools, including XCode, Ninja, and Eclipse. It also eliminates the
need to install autotools via MacPorts/Homebrew on OS X and allows
libjpeg-turbo to be configured without the use of a terminal/command prompt.
Extensive testing was conducted to ensure that all features provided by the
autotools-based build system are provided by the new build system.
3. The libjpeg API in this version of libjpeg-turbo now includes two additional
functions, `jpeg_read_icc_profile()` and `jpeg_write_icc_profile()`, that can
be used to extract ICC profile data from a JPEG file while decompressing or to
embed ICC profile data in a JPEG file while compressing or transforming. This
eliminates the need for downstream projects, such as color management libraries
and browsers, to include their own glueware for accomplishing this.
4. Improved error handling in the TurboJPEG API library:
- Introduced a new function (`tjGetErrorStr2()`) in the TurboJPEG C API
that allows compression/decompression/transform error messages to be retrieved
in a thread-safe manner. Retrieving error messages from global functions, such
as `tjInitCompress()` or `tjBufSize()`, is still thread-unsafe, but since those
functions will only throw errors if passed an invalid argument or if a memory
allocation failure occurs, thread safety is not as much of a concern.
- Introduced a new function (`tjGetErrorCode()`) in the TurboJPEG C API
and a new method (`TJException.getErrorCode()`) in the TurboJPEG Java API that
can be used to determine the severity of the last
compression/decompression/transform error. This allows applications to
choose whether to ignore warnings (non-fatal errors) from the underlying
libjpeg API or to treat them as fatal.
- Introduced a new flag (`TJFLAG_STOPONWARNING` in the TurboJPEG C API and
`TJ.FLAG_STOPONWARNING` in the TurboJPEG Java API) that causes the library to
immediately halt a compression/decompression/transform operation if it
encounters a warning from the underlying libjpeg API (the default behavior is
to allow the operation to complete unless a fatal error is encountered.)
5. Introduced a new flag in the TurboJPEG C and Java APIs (`TJFLAG_PROGRESSIVE`
and `TJ.FLAG_PROGRESSIVE`, respectively) that causes the library to use
progressive entropy coding in JPEG images generated by compression and
transform operations. Additionally, a new transform option
(`TJXOPT_PROGRESSIVE` in the C API and `TJTransform.OPT_PROGRESSIVE` in the
Java API) has been introduced, allowing progressive entropy coding to be
enabled for selected transforms in a multi-transform operation.
6. Introduced a new transform option in the TurboJPEG API (`TJXOPT_COPYNONE` in
the C API and `TJTransform.OPT_COPYNONE` in the Java API) that allows the
copying of markers (including EXIF and ICC profile data) to be disabled for a
particular transform.
7. Added two functions to the TurboJPEG C API (`tjLoadImage()` and
`tjSaveImage()`) that can be used to load/save a BMP or PPM/PGM image to/from a
memory buffer with a specified pixel format and layout. These functions
replace the project-private (and slow) bmp API, which was previously used by
TJBench, and they also provide a convenient way for first-time users of
libjpeg-turbo to quickly develop a complete JPEG compression/decompression
program.
8. The TurboJPEG C API now includes a new convenience array (`tjAlphaOffset[]`)
that contains the alpha component index for each pixel format (or -1 if the
pixel format lacks an alpha component.) The TurboJPEG Java API now includes a
new method (`TJ.getAlphaOffset()`) that returns the same value. In addition,
the `tjRedOffset[]`, `tjGreenOffset[]`, and `tjBlueOffset[]` arrays-- and the
corresponding `TJ.getRedOffset()`, `TJ.getGreenOffset()`, and
`TJ.getBlueOffset()` methods-- now return -1 for `TJPF_GRAY`/`TJ.PF_GRAY`
rather than 0. This allows programs to easily determine whether a pixel format
has red, green, blue, and alpha components.
9. Added a new example (tjexample.c) that demonstrates the basic usage of the
TurboJPEG C API. This example mirrors the functionality of TJExample.java.
Both files are now included in the libjpeg-turbo documentation.
10. Fixed two signed integer overflows in the arithmetic decoder, detected by
the Clang undefined behavior sanitizer, that could be triggered by attempting
to decompress a specially-crafted malformed JPEG image. These issues did not
pose a security threat, but removing the warnings makes it easier to detect
actual security issues, should they arise in the future.
11. Fixed a bug in the merged 4:2:0 upsampling/dithered RGB565 color conversion
algorithm that caused incorrect dithering in the output image. This algorithm
now produces bitwise-identical results to the unmerged algorithms.
12. The SIMD function symbols for x86[-64]/ELF, MIPS/ELF, macOS/x86[-64] (if
libjpeg-turbo is built with YASM), and iOS/ARM[64] builds are now private.
This prevents those symbols from being exposed in applications or shared
libraries that link statically with libjpeg-turbo.
13. Added Loongson MMI SIMD implementations of the RGB-to-YCbCr and
YCbCr-to-RGB colorspace conversion, 4:2:0 chroma downsampling, 4:2:0 fancy
chroma upsampling, integer quantization, and slow integer DCT/IDCT algorithms.
When using the slow integer DCT/IDCT, this speeds up the compression of RGB
images by approximately 70-100% and the decompression of RGB images by
approximately 2-3.5x.
14. Fixed a build error when building with older MinGW releases (regression
caused by 1.5.1[7].)
15. Added SIMD acceleration for progressive Huffman encoding on SSE2-capable
x86 and x86-64 platforms. This speeds up the compression of full-color
progressive JPEGs by about 85-90% on average (relative to libjpeg-turbo 1.5.x)
when using modern Intel and AMD CPUs.

### Significant changes relative to 1.5.2:
1. Fixed a NullPointerException in the TurboJPEG Java wrapper that occurred
when using the YUVImage constructor that creates an instance backed by separate
image planes and allocates memory for the image planes.
2. Fixed an issue whereby the Java version of TJUnitTest would fail when
testing BufferedImage encoding/decoding on big endian systems.
3. Fixed a segfault in djpeg that would occur if an output format other than
PPM/PGM was selected along with the `-crop` option. The `-crop` option now
works with the GIF and Targa formats as well (unfortunately, it cannot be made
to work with the BMP and RLE formats due to the fact that those output engines
write scanlines in bottom-up order.) djpeg will now exit gracefully if an
output format other than PPM/PGM, GIF, or Targa is selected along with the
`-crop` option.
4. Fixed an issue (CVE-2017-15232) whereby `jpeg_skip_scanlines()` would
segfault if color quantization was enabled.
5. TJBench (both C and Java versions) will now display usage information if any
command-line argument is unrecognized. This prevents the program from silently
ignoring typos.
6. Fixed an access violation in tjbench.exe (Windows) that occurred when the
program was used to decompress an existing JPEG image.
7. Fixed an ArrayIndexOutOfBoundsException in the TJExample Java program that
occurred when attempting to decompress a JPEG image that had been compressed
with 4:1:1 chrominance subsampling.
8. Fixed an issue whereby, when using `jpeg_skip_scanlines()` to skip to the
end of a single-scan (non-progressive) image, subsequent calls to
`jpeg_consume_input()` would return `JPEG_SUSPENDED` rather than
`JPEG_REACHED_EOI`.
9. `jpeg_crop_scanlines()` now works correctly when decompressing grayscale
JPEG images that were compressed with a sampling factor other than 1 (for
instance, with `cjpeg -grayscale -sample 2x2`).
1.5.2
=====
### Significant changes relative to 1.5.1:
1. Fixed a regression introduced by 1.5.1[7] that prevented libjpeg-turbo from
building with Android NDK platforms prior to android-21 (5.0).
2. Fixed a regression introduced by 1.5.1[1] that prevented the MIPS DSPR2 SIMD
code in libjpeg-turbo from building.
3. Fixed a regression introduced by 1.5 beta1[11] that prevented the Java
version of TJBench from outputting any reference images (the `-nowrite` switch
was accidentally enabled by default.)
4. libjpeg-turbo should now build and run with full AltiVec SIMD acceleration
on PowerPC-based AmigaOS 4 and OpenBSD systems.
5. Fixed build and runtime errors on Windows that occurred when building
libjpeg-turbo with libjpeg v7 API/ABI emulation and the in-memory
source/destination managers. Due to an oversight, the `jpeg_skip_scanlines()`
and `jpeg_crop_scanlines()` functions were not being included in jpeg7.dll when
libjpeg-turbo was built with `-DWITH_JPEG7=1` and `-DWITH_MEMSRCDST=1`.
6. Fixed "Bogus virtual array access" error that occurred when using the
lossless crop feature in jpegtran or the TurboJPEG API, if libjpeg-turbo was
built with libjpeg v7 API/ABI emulation. This was apparently a long-standing
bug that has existed since the introduction of libjpeg v7/v8 API/ABI emulation
in libjpeg-turbo v1.1.
7. The lossless transform features in jpegtran and the TurboJPEG API will now
always attempt to adjust the EXIF image width and height tags if the image size
changed as a result of the transform. This behavior has always existed when
using libjpeg v8 API/ABI emulation. It was supposed to be available with
libjpeg v7 API/ABI emulation as well but did not work properly due to a bug.
Furthermore, there was never any good reason not to enable it with libjpeg v6b
API/ABI emulation, since the behavior is entirely internal. Note that
`-copy all` must be passed to jpegtran in order to transfer the EXIF tags from
the source image to the destination image.
8. Fixed several memory leaks in the TurboJPEG API library that could occur
if the library was built with certain compilers and optimization levels
(known to occur with GCC 4.x and clang with `-O1` and higher but not with
GCC 5.x or 6.x) and one of the underlying libjpeg API functions threw an error
after a TurboJPEG API function allocated a local buffer.
9. The libjpeg-turbo memory manager will now honor the `max_memory_to_use`
structure member in jpeg\_memory\_mgr, which can be set to the maximum amount
of memory (in bytes) that libjpeg-turbo should use during decompression or
multi-pass (including progressive) compression. This limit can also be set
using the `JPEGMEM` environment variable or using the `-maxmemory` switch in
cjpeg/djpeg/jpegtran (refer to the respective man pages for more details.)
This has been a documented feature of libjpeg since v5, but the
`malloc()`/`free()` implementation of the memory manager (jmemnobs.c) never
implemented the feature. Restricting libjpeg-turbo's memory usage is useful
for two reasons: it allows testers to more easily work around the 2 GB limit
in libFuzzer, and it allows developers of security-sensitive applications to
more easily defend against one of the progressive JPEG exploits (LJT-01-004)
identified in
[this report](http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf).
10. TJBench will now run each benchmark for 1 second prior to starting the
timer, in order to improve the consistency of the results. Furthermore, the
`-warmup` option is now used to specify the amount of warmup time rather than
the number of warmup iterations.
11. Fixed an error (`short jump is out of range`) that occurred when assembling
the 32-bit x86 SIMD extensions with NASM versions prior to 2.04. This was a
regression introduced by 1.5 beta1[12].
1.5.1
=====
### Significant changes relative to 1.5.0:
1. Previously, the undocumented `JSIMD_FORCE*` environment variables could be
used to force-enable a particular SIMD instruction set if multiple instruction
sets were available on a particular platform. On x86 platforms, where CPU
feature detection is bulletproof and multiple SIMD instruction sets are
available, it makes sense for those environment variables to allow forcing the
use of an instruction set only if that instruction set is available. However,
since the ARM implementations of libjpeg-turbo can only use one SIMD
instruction set, and since their feature detection code is less bulletproof
(parsing /proc/cpuinfo), it makes sense for the `JSIMD_FORCENEON` environment
variable to bypass the feature detection code and really force the use of NEON
instructions. A new environment variable (`JSIMD_FORCEDSPR2`) was introduced
in the MIPS implementation for the same reasons, and the existing
`JSIMD_FORCENONE` environment variable was extended to that implementation.
These environment variables provide a workaround for those attempting to test
ARM and MIPS builds of libjpeg-turbo in QEMU, which passes through
/proc/cpuinfo from the host system.
2. libjpeg-turbo previously assumed that AltiVec instructions were always
available on PowerPC platforms, which led to "illegal instruction" errors when
running on PowerPC chips that lack AltiVec support (such as the older 7xx/G3
and newer e5500 series.) libjpeg-turbo now examines /proc/cpuinfo on
Linux/Android systems and enables AltiVec instructions only if the CPU supports
them. It also now provides two environment variables, `JSIMD_FORCEALTIVEC` and
`JSIMD_FORCENONE`, to force-enable and force-disable AltiVec instructions in
environments where /proc/cpuinfo is an unreliable means of CPU feature
detection (such as when running in QEMU.) On OS X, libjpeg-turbo continues to
assume that AltiVec support is always available, which means that libjpeg-turbo
cannot be used with G3 Macs unless you set the environment variable
`JSIMD_FORCENONE` to `1`.
3. Fixed an issue whereby 64-bit ARM (AArch64) builds of libjpeg-turbo would
crash when built with recent releases of the Clang/LLVM compiler. This was
caused by an ABI conformance issue in some of libjpeg-turbo's 64-bit NEON SIMD
routines. Those routines were incorrectly using 64-bit instructions to
transfer a 32-bit JDIMENSION argument, whereas the ABI allows the upper
(unused) 32 bits of a 32-bit argument's register to be undefined. The new
Clang/LLVM optimizer uses load combining to transfer multiple adjacent 32-bit
structure members into a single 64-bit register, and this exposed the ABI
conformance issue.
4. Fancy upsampling is now supported when decompressing JPEG images that use
4:4:0 (h1v2) chroma subsampling. These images are generated when losslessly
rotating or transposing JPEG images that use 4:2:2 (h2v1) chroma subsampling.
The h1v2 fancy upsampling algorithm is not currently SIMD-accelerated.
5. If merged upsampling isn't SIMD-accelerated but YCbCr-to-RGB conversion is,
then libjpeg-turbo will now disable merged upsampling when decompressing YCbCr
JPEG images into RGB or extended RGB output images. This significantly speeds
up the decompression of 4:2:0 and 4:2:2 JPEGs on ARM platforms if fancy
upsampling is not used (for example, if the `-nosmooth` option to djpeg is
specified.)
6. The TurboJPEG API will now decompress 4:2:2 and 4:4:0 JPEG images with
2x2 luminance sampling factors and 2x1 or 1x2 chrominance sampling factors.
This is a non-standard way of specifying 2x subsampling (normally 4:2:2 JPEGs
have 2x1 luminance and 1x1 chrominance sampling factors, and 4:4:0 JPEGs have
1x2 luminance and 1x1 chrominance sampling factors), but the JPEG format and
the libjpeg API both allow it.
7. Fixed an unsigned integer overflow in the libjpeg memory manager, detected
by the Clang undefined behavior sanitizer, that could be triggered by
attempting to decompress a specially-crafted malformed JPEG image. This issue
affected only 32-bit code and did not pose a security threat, but removing the
warning makes it easier to detect actual security issues, should they arise in
the future.
8. Fixed additional negative left shifts and other issues reported by the GCC
and Clang undefined behavior sanitizers when attempting to decompress
specially-crafted malformed JPEG images. None of these issues posed a security
threat, but removing the warnings makes it easier to detect actual security
issues, should they arise in the future.
9. Fixed an out-of-bounds array reference, introduced by 1.4.90[2] (partial
image decompression) and detected by the Clang undefined behavior sanitizer,
that could be triggered by a specially-crafted malformed JPEG image with more
than four components. Because the out-of-bounds reference was still within the
same structure, it was not known to pose a security threat, but removing the
warning makes it easier to detect actual security issues, should they arise in
the future.
10. Fixed another ABI conformance issue in the 64-bit ARM (AArch64) NEON SIMD
code. Some of the routines were incorrectly reading and storing data below the
stack pointer, which caused segfaults in certain applications under specific
circumstances.

================
FILE FORMAT COMPATIBILITY
=========================
The ISO/IEC JTC1/SC29/WG1 standards committee (also known as JPEG, together
with ITU-T SG16) currently promotes different formats containing the name
"JPEG" which are incompatible with original DCT-based JPEG. IJG therefore does
not support these formats (see REFERENCES). Indeed, one of the original
reasons for developing this free software was to help force convergence on
common, interoperable format standards for JPEG files.
Don't use an incompatible file format!
(In any case, our decoder will remain capable of reading existing JPEG
image files indefinitely.)
This software implements ITU T.81 | ISO/IEC 10918 with some extensions from
ITU T.871 | ISO/IEC 10918-5 (JPEG File Interchange Format-- see REFERENCES).
Informally, the term "JPEG image" or "JPEG file" most often refers to JFIF or
a subset thereof, but there are other formats containing the name "JPEG" that
are incompatible with the DCT-based JPEG standard or with JFIF (for instance,
JPEG 2000 and JPEG XR). This software therefore does not support these
formats. Indeed, one of the original reasons for developing this free software
was to help force convergence on a common, interoperable format standard for
JPEG files.
JFIF is a minimal or "low end" representation. TIFF/JPEG (TIFF revision 6.0 as
modified by TIFF Technical Note #2) can be used for "high end" applications
that need to record a lot of additional data about an image.

> Instagram had [a security vulnerability](https://m.facebook.com/security/advisories/cve-2020-1895). Instagram uses MozJPEG. These two facts were somewhat conflated in the [vulnerability report](https://research.checkpoint.com/2020/instagram_rce-code-execution-vulnerability-in-instagram-app-for-android-and-ios/) that gets reposted all over the Internet right now.

============================
MozJPEG reduces file sizes of JPEG images while retaining quality and compatibility with the vast majority of the world's deployed decoders.
MozJPEG is based on [libjpeg-turbo](https://github.com/libjpeg-turbo/libjpeg-turbo). It's compatible with libjpeg API and ABI, and can be used as a drop-in replacement for libjpeg. MozJPEG makes tradeoffs that are intended to benefit Web use cases and focuses solely on improving encoding, so it's best used as part of a Web encoding workflow.
MozJPEG is based on [libjpeg-turbo](https://github.com/libjpeg-turbo/libjpeg-turbo). **Please send pull requests to libjpeg-turbo** if the changes aren't specific to newly-added MozJPEG-only compression code. This project aims to keep differences with libjpeg-turbo minimal, so whenever possible, improvements and bug fixes should go there first.

#.rst:
# GNUInstallDirs
# --------------
#
# Define GNU standard installation directories
#
# Provides install directory variables as defined by the
# `GNU Coding Standards`_.
#
# .. _`GNU Coding Standards`: https://www.gnu.org/prep/standards/html_node/Directory-Variables.html
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# Inclusion of this module defines the following variables:
#
# ``CMAKE_INSTALL_<dir>``
#
# Destination for files of a given type. This value may be passed to
# the ``DESTINATION`` options of :command:`install` commands for the
# corresponding file type.
#
# ``CMAKE_INSTALL_FULL_<dir>``
#
# The absolute path generated from the corresponding ``CMAKE_INSTALL_<dir>``
# value. If the value is not already an absolute path, an absolute path
# is constructed typically by prepending the value of the
# :variable:`CMAKE_INSTALL_PREFIX` variable. However, there are some
# `special cases`_ as documented below.
#
# where ``<dir>`` is one of:
#
# ``BINDIR``
# user executables (``bin``)
# ``SBINDIR``
# system admin executables (``sbin``)
# ``LIBEXECDIR``
# program executables (``libexec``)
# ``SYSCONFDIR``
# read-only single-machine data (``etc``)
# ``SHAREDSTATEDIR``
# modifiable architecture-independent data (``com``)
# ``LOCALSTATEDIR``
# modifiable single-machine data (``var``)
# ``LIBDIR``
# object code libraries (``lib`` or ``lib64``
# or ``lib/<multiarch-tuple>`` on Debian)
# ``INCLUDEDIR``
# C header files (``include``)
# ``OLDINCLUDEDIR``
# C header files for non-gcc (``/usr/include``)
# ``DATAROOTDIR``
# read-only architecture-independent data root (``share``)
# ``DATADIR``
# read-only architecture-independent data (``DATAROOTDIR``)
# ``INFODIR``
# info documentation (``DATAROOTDIR/info``)
# ``LOCALEDIR``
# locale-dependent data (``DATAROOTDIR/locale``)
# ``MANDIR``
# man documentation (``DATAROOTDIR/man``)
# ``DOCDIR``
# documentation root (``DATAROOTDIR/doc/PROJECT_NAME``)
#
# If the includer does not define a value the above-shown default will be
# used and the value will appear in the cache for editing by the user.
#
# Special Cases
# ^^^^^^^^^^^^^
#
# The following values of :variable:`CMAKE_INSTALL_PREFIX` are special:
#
# ``/``
#
# For ``<dir>`` other than the ``SYSCONFDIR`` and ``LOCALSTATEDIR``,
# the value of ``CMAKE_INSTALL_<dir>`` is prefixed with ``usr/`` if
# it is not user-specified as an absolute path. For example, the
# ``INCLUDEDIR`` value ``include`` becomes ``usr/include``.
# This is required by the `GNU Coding Standards`_, which state:
#
# When building the complete GNU system, the prefix will be empty
# and ``/usr`` will be a symbolic link to ``/``.
#
# ``/usr``
#
# For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
# ``CMAKE_INSTALL_FULL_<dir>`` is computed by prepending just ``/``
# to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
# as an absolute path. For example, the ``SYSCONFDIR`` value ``etc``
# becomes ``/etc``. This is required by the `GNU Coding Standards`_.
#
# ``/opt/...``
#
# For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
# ``CMAKE_INSTALL_FULL_<dir>`` is computed by *appending* the prefix
# to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
# as an absolute path. For example, the ``SYSCONFDIR`` value ``etc``
# becomes ``/etc/opt/...``. This is defined by the
# `Filesystem Hierarchy Standard`_.
#
# .. _`Filesystem Hierarchy Standard`: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html
#
# Macros
# ^^^^^^
#
# .. command:: GNUInstallDirs_get_absolute_install_dir
#
# ::
#
# GNUInstallDirs_get_absolute_install_dir(absvar var)
#
# Set the given variable ``absvar`` to the absolute path contained
# within the variable ``var``. This is to allow the computation of an
# absolute path, accounting for all the special cases documented
# above. While this macro is used to compute the various
# ``CMAKE_INSTALL_FULL_<dir>`` variables, it is exposed publicly to
# allow users who create additional path variables to also compute
# absolute paths where necessary, using the same logic.
