Måns Rullgård	edd7fa82d7	ARM: intmath.h cosmetics Originally committed as revision 24088 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	2ed6f39944	Replace many includes of libavutil/common.h with what is actually needed This reduces the number of false dependencies on header files and speeds up compilation. Originally committed as revision 22407 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4a89e0a675	ARM: add some missing includes Originally committed as revision 22340 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	ac73f1a816	ARM: change argument/return type of bswap_16() to unsigned 32-bit This avoids unnecessary masking otherwise added by the compilers. Originally committed as revision 21953 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	75fb5c24ed	Move FASTDIV macro to intmath.h Originally committed as revision 21335 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	bdd19e29df	Mark all intreadwrite functions av_always_inline Originally committed as revision 21278 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	e6956a6e48	ARM: first value loaded in AV_RN64 needs to be early-clobber Originally committed as revision 19656 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	300ad6c16e	ARM: use gcc inline asm in bswap.h only when available Originally committed as revision 19311 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	60c703ac4b	ARM: START/STOP_TIMER support for ARMv7 Originally committed as revision 18305 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	1e65f62e2b	ARM: armcc versions of bswap_16/32 Originally committed as revision 17830 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Aurelien Jacobs	b250f9c66d	Change semantic of CONFIG_, HAVE_ and ARCH_*. They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	3a90480ac4	split bswap.h into per-arch files Originally committed as revision 15663 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
