2015-03-17x86: Put COPY3_IF_LT under HAVE_6REGSLuca Barbato
It uses 6 registers, unbreaks building on hardened x86 system. Bug-Id: gentoo/541930 CC: libav-stable@libav.org
2014-04-19Fix compilation with !HAVE_6REGS.Carl Eugen Hoyos
Can be tested with: $ ./configure --cc='cc -m32' --disable-optimizations --enable-pic

* commit 'f54b55058a429c4eea5bae7e5bcb49bd29b34199': configure: Rename cmov processor capability to i686 Merged-by: Michael Niedermayer <michaelni@gmx.at>
2013-05-12configure: Rename cmov processor capability to i686Diego Biurrun
The goal is to make the capapility slightly more general and have it cover the availability of the nopl instruction in addition to cmov.

2012-08-09Move MASK_ABS macro to libavcodec/mathops.hMans Rullgard
This macro is only used in two places, both in libavcodec, so this is a more sensible place for it. Two small tweaks to the macro are made: - removing the trailing semicolon - dropping unnecessary 'volatile' from the x86 asm Signed-off-by: Mans Rullgard <mans@mansr.com>

2011-03-16mathops: fix MULL() when the compiler does not inline the function.Justin Ruggles
If the function is not inlined, an immmediate cannot be used for the shift parameter, so the %cl register must be used instead in that case. This fixes compilation for x86-32 using gcc with --disable-optimizations.
2011-03-15mathops: change "g" constraint to "rm" in x86-32 version of MUL64().Justin Ruggles
The 1-arg imul instruction cannot take an immediate argument, only a register or memory argument.
2011-03-15mathops: convert MULL/MULH/MUL64 to inline functions rather than macros.Justin Ruggles
This fixes unexpected name collisions that were occurring with variables declared within the macros. It also fixes the fate-acodec-ac3_fixed regression test on x86-32.

2010-01-20Move COPY3_IF_LT to lavc/mathops.hMåns Rullgård
This obscure macro is only used in motion_est.c so having it in lavc makes more sense. See discussion here: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2008-November/056561.html Originally committed as revision 21346 to svn://svn.ffmpeg.org/ffmpeg/trunk

2008-12-22Rename libavcodec/i386/ --> libavcodec/x86/.Diego Biurrun
It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk
