| * ARM: allow runtime masking of CPU featuresMans Rullgard2012-04-223-0/+63
| | | | | | | | | | | | | | This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | | | | | The were broken since August of 2010 without anyone noticing until three weeks ago. Nobody cares about it anymore and hopefully Marvell will support NEON like in the PXA978 from now on.

* ARM asm for AV_RN*()Måns Rullgård2009-04-181-0/+78
| | | | | | | | | | | | | | | 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
