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. Originally committed as revision 18602 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	3c55ce039d	ARM asm for AV_RN() ARMv6 and later support unaligned loads and stores for single word/halfword but not double/multiple. GCC is ignorant of this and will always use bytewise accesses for unaligned data. Casting to an int32_t pointer is dangerous since a load/store double or multiple instruction might be used (this happens with some code in FFmpeg). Implementing the AV_[RW] macros with inline asm using only supported instructions gives fast and safe unaligned accesses. ARM RVCT does the right thing with generic code. This gives an overall speedup of up to 10%. Originally committed as revision 18601 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	a6783b8961	Reorganise intreadwrite.h This changes intreadwrite.h to support per-arch implementations of the various macros allowing us to take advantage of special instructions or other properties the compiler does not know about.
