| * cabac: split cabac.h into declarations and function definitionsDiego Biurrun2012-01-12
| | | | | | | | | | | | | | | | | | | | | | This fixes standalone compilation of some decoders with --disable-optimizations. cabac.h defines some inline functions that use symbols from cabac.c. Without optimizations these inline functions are not eliminated and linking fails with references to non-existing symbols. Splitting the inline functions off into their own header and only #including it in the places where the inline functions are used allows #including cabac.h from anywhere without ill effects.

| * x86: Fix constraints for decode_significance*_x86Martin Storsjö2011-12-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, prior to 8742a4ff8, the caller code was compiled within this condition: ARCH_X86 && HAVE_7REGS && HAVE_EBX_AVAILABLE && !defined(BROKEN_RELOCATIONS) Since HAVE_7REGS is defined as (ARCH_X86_64 || (HAVE_EBX_AVAILABLE && HAVE_EBP_AVAILABLE)) the subcondition HAVE_7REGS && HAVE_EBX_AVAILABLE is equal to HAVE_7REGS (for 32 bit at least). The correct simplification of the original condition thus is HAVE_7REGS, not HAVE_EBX_AVAILABLE. This fixes compilation in some cases where HAVE_EBP_AVAILABLE = 0 and HAVE_EBX_AVAILABLE = 1.

* H.264: switch to x264-style tracking of luma/chroma DC NNZJason Garrett-Glaser2011-01-14
