Author: reimar
Date: Sun Dec 3 17:35:30 2006
New Revision: 7218
Added:
trunk/libavutil/intreadwrite.h
Modified:
trunk/libavcodec/avcodec.h
trunk/libavcodec/dsputil.h
trunk/libavutil/internal.h
Log:
Move BE_*/LE_*/ST*/LD* macros to a common place. Some further
optimization/cleanup would be desirable (e.g. LE_* and LD*
should be the same on x86).
