* Include attributes.h directlyAndreas Rheinhardt2021-04-19
| | | | | | | | Some files currently rely on libavutil/cpu.h to include it for them; yet said file won't use include it any more after the currently deprecated functions are removed, so include attributes.h directly. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* swscale/x86/swscale: Remove unused ASM constantsAndreas Rheinhardt2021-02-24
| | | | | | | | | | | | | The last user of g15Mask, r15Mask, g16Mask and r16Mask was disabled in 77a416e8aab77058b542030870fd7178b62d2a62 and finally removed in 36e8de07ed62609df45d064b56501e3084d25723; b15Mask and b16Mask were apparently always unused (except for in_asm_used_var_warning_killer, a function that only existed to make the compiler not optimize ASM constants away). w10 is unused since d604bab901f6dfaaad672ef2164e42b1f350474c, w02 since ef423a661818f3c0d8206a2abbc65ff555cc0c67.

| | | | | | | | | This affected many FATE-tests: The number of failing tests went down from 663 to 344. (Both numbers exclude tests that failed because of unaligned accesses in code that is inside #if HAVE_FAST_UNALIGNED.)

* swscale: Add support for NV24 and NV42Philip Langdale2019-05-12
| | | | | | | | | | | The implementation is pretty straight-forward. Most of the existing NV12 codepaths work regardless of subsampling and are re-used as is. Where necessary I wrote the slightly different NV24 versions. Finally, the one thing that confused me for a long time was the asm specific x86 path that did an explicit exclusion check for NV12. I replaced that with a semi-planar check and also updated the equivalent PPC code, which Lauri kindly checked.

* Fix missing used attribute for inline assembly variablesThomas Köppe2017-11-13
| | | | | | | | | | | | | Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* | swscale: save ebx register when it is not availableAndreas Cadhalpun2016-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Configure checks if the ebx register can be used for asm and it has to be saved if and only if this is not the case. Without this the build fails when configuring with --toolchain=hardened --disable-pic on i386 using gcc 4.8: error: PIC register clobbered by '%ebx' in 'asm' In that case gcc 4.8 reserves the ebx register for the GOT needed for PIE, so it can't be used in asm directly.
