DRC	890f35098a	Create a separate stub file for 64-bit ARM, since it currently implements only the decompression-related functions.	2014-02-05 19:03:41 +00:00
DRC	1bb1e69186	First pass at ARMv8 64-bit NEON SIMD support	2014-02-05 08:15:44 +00:00

DRC	bd029eb0f7	Make environment variable syntax consistent between ARM and x86 code, and add an option to disable SIMD on x86 (this option will be added to the x86-64 code as well, but it makes more sense to add it when we add AVX support.)	2013-10-31 07:40:24 +00:00

DRC	c4c137f5e9	Fix the x86 build with NASM 0.98. Since NASM 0.98 is the default version on OS X, we want to at least allow people to build 32-bit code with it, even though it can't properly build 64-bit code.	2013-01-13 12:12:53 +00:00
DRC	f506e2cbb5	Fix build issues that occurred whenever the source directory contained the letters "col", "mer", or "gra".	2012-08-07 21:59:28 +00:00
DRC	7b8366223a	More recent versions of autoconf add -traditional-cpp to the CPP flags, which causes jsimdcfg.inc.h to not preprocess correctly unless we expand all of the instances of the #definev macro.	2012-06-28 23:24:29 +00:00
DRC	791e9b4316	Fixed regression caused by a bug in the 32-bit strict memory access code in jdmrgss2.asm (contributed by Chromium to stop valgrind from whining whenever the output buffer size was not evenly divisible by 16 bytes.) On Linux/x86, this regression caused incorrect pixels on the right-hand side of images whose rows were not 16-byte aligned, whenever fancy upsampling was used. This patch also enables the strict memory access code on all platforms, not just Linux (it does no harm on other platforms) and removes a couple of pcmpeqb instructions that were rendered unnecessary by r836.	2012-06-15 21:58:06 +00:00
DRC	7702469e15	Eliminate the use of the MASKMOVDQU instruction, to speed up decompression performance by 10x on AMD Bobcat embedded processors (and ~5% on AMD desktop processors.)	2012-06-13 01:23:09 +00:00

DRC	c1e4151607	Added new alpha channel colorspace constants/pixel formats, so applications can specify that they need the unused byte in a 4-component RGB output buffer set to 0xFF when decompressing.	2011-12-19 02:21:03 +00:00
DRC	90d7c850fa	Fixed non-fatal out-of-bounds read in SSE2 SIMD code reported by valgrind when decompressing a JPEG image to a bitmap buffer whose size was not a multiple of 16 bytes.	2011-12-01 10:58:36 +00:00
DRC	8ec31e2fb2	Expose NASM variable in ccmake	2011-11-29 09:01:23 +00:00
DRC	e0eea893be	NASM automatically adds the current directory to the include path, but YASM doesn't, so we need to explicitly add it.	2011-11-29 08:58:27 +00:00
DRC	d345306ecc	When decompressing to a 4-byte RGB buffer, set the unused byte to 0xFF so it can be interpreted as an opaque alpha channel.	2011-09-08 23:54:40 +00:00
