Huh? The only other ones seem to be decode_significance as far as I can
tell, and the only reason seems to be that they use
Have you tried making them use your BRANCHLESS_GET_CABAC macro?
Code is in libavcodec/x86/h264_i386.h.
since the macros are used multiple times the label might cause issues.
So far that reason and
for better readability it might be better to require the surrounding
code to have such a label instead of having it in the macro?
