* build: Generalize yasm/nasm-related variable namesDiego Biurrun2017-06-211-1/+1
| | | | | | | | None of them are specific to the YASM assembler. (Cherry-picked from libav commit 39e208f4d4756367c7cd2d581847e0c1b8a429c1) Signed-off-by: James Almer <jamrial@gmail.com>
* x86inc: Drop SECTION_TEXT macroHenrik Gramner2015-08-043-3/+3
| | | | | 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>

| * x86: lavr: fix stack allocation for 7 and 8 channel downmixing on x86-32Ronald S. Bultje2012-11-171-1/+9
| | | | | | | | Fixes crashes on Win32 and stack overruns on x86-32 in general.
| * build: Drop AVX assembly ifdefsDiego Biurrun2012-11-112-42/+0
|/ | | | An assembler able to cope with AVX instructions is now required.

|
* x86: avresample: Add missing colons to assembly labelsDiego Biurrun2012-11-061-2/+2
| | | | YASM accepts labels without colons, but NASM issues warnings.
* x86: yasm: Use complete source path for macro helper %includesDiego Biurrun2012-10-312-2/+2
| | | | | This is more consistent with the way we handle C #includes and it simplifies the build system.
* x86: include x86inc.asm in x86util.asmDiego Biurrun2012-10-312-2/+0
| | | | This is necessary to allow refactoring some x86util macros with cpuflags.
* lavr: handle clipping in the float to s32 conversionJustin Ruggles2012-10-131-1/+7
| | | | | | | | | | | 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>
* x86: Replace checks for CPU extensions and flags by convenience macrosDiego Biurrun2012-09-082-17/+17
| | | | | This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.
