2015-08-04x86inc: Drop SECTION_TEXT macroHenrik Gramner
The .text section is already 16-byte aligned by default on all supported platforms so `SECTION_TEXT` isn't any different from `SECTION .text`.

Dead code elimination is enough to avoid undefined references in these cases.

This is so we can sync to x264's version of FMA4 support. This partialy reverts commit 79687079a97a039c325ab79d7a95920d800b791f. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

2012-11-18x86: lavr: fix stack allocation for 7 and 8 channel downmixing on x86-32Ronald S. Bultje
Fixes crashes on Win32 and stack overruns on x86-32 in general.
2012-11-11build: Drop AVX assembly ifdefsDiego Biurrun
An assembler able to cope with AVX instructions is now required.
2012-11-10x86: PALIGNR: port to cpuflagsDiego Biurrun
2012-11-06x86: avresample: Add missing colons to assembly labelsDiego Biurrun
YASM accepts labels without colons, but NASM issues warnings.
2012-10-31x86: yasm: Use complete source path for macro helper %includesDiego Biurrun
This is more consistent with the way we handle C #includes and it simplifies the build system.
2012-10-31x86: include x86inc.asm in x86util.asmDiego Biurrun
This is necessary to allow refactoring some x86util macros with cpuflags.
2012-10-13lavr: handle clipping in the float to s32 conversionJustin Ruggles
We cannot clip to INT_MAX because that value cannot be exactly represented by a float value and ends up overflowing during conversion anyway. We need to use a slightly smaller float value, which ends up with slightly inaccurate results for samples which clip or nearly clip, but it is close enough. Using doubles as intermediates in the conversion would be more accurate, but it takes about twice as much time. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2012-09-08x86: Replace checks for CPU extensions and flags by convenience macrosDiego Biurrun
This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.

Removes a false dependency on existing contents of the 2nd dst register, giving better performance for OOE.
