Philip Langdale	cd48318035	swscale: Add support for NV24 and NV42 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.	6 years ago

Thomas Köppe	43171a2a73	Fix missing used attribute for inline assembly variables 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>	7 years ago

Andreas Cadhalpun	319438e2f2	swscale: save ebx register when it is not available 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.
