Måns Rullgård	b6ec1f47c7	PPC: fix asm operand constraints in AV_RL64 ... The target register of first word loaded must be marked early-clobber. Originally committed as revision 19536 to svn://svn.ffmpeg.org/ffmpeg/trunk	2009-07-29 19:06:55 +00:00

Måns Rullgård	9f5ff83f2a	PPC asm for AV_RL*() ... PPC is normally big endian but has special little endian load/store instructions. Using these avoids a separate byteswap. This makes the vorbis decoder about 5% faster. Not much else uses little-endian read/write extensively. GCC generates horrible PPC code for the default AV_[RW]B64 (which uses a packed struct), so we override it with a plain pointer cast.
