DRC b87a0b46 2013-01-13T12:15:58 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. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.2.x@906 632fc199-4ca6-4c93-a231-07263d6284db
DRC 13c318da 2012-06-18T00:16:15 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 and when decompressing to a 32-bit (RGBX, etc.) buffer. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.0.x@843 632fc199-4ca6-4c93-a231-07263d6284db
DRC 8126d0c5 2012-06-15T21:54:45 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 generated 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 r835. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.2.x@838 632fc199-4ca6-4c93-a231-07263d6284db
DRC 69799275 2012-06-13T01:21:29 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.) git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.2.x@835 632fc199-4ca6-4c93-a231-07263d6284db
DRC 795e6ad3 2011-12-01T11:14:18 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. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.0.x@729 632fc199-4ca6-4c93-a231-07263d6284db
