| * ARM: allow runtime masking of CPU featuresMans Rullgard2012-04-2214-24/+76
| | | | | | | | | | | | | | 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>

| * avcodec: remove AVCodecContext.dsp_maskMans Rullgard2012-04-214-15/+8
| | | | | | | | | | | | | | | | This removes all references to AVCodecContext.dsp_mask and marks it for eviction at the next version bump. It has been superseded by av_set_cpu_flag_mask() which, unlike this field, works everywhere. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | | | | | | | | | | | General cosmetics, such as keeping lines under 80 characters, fixing a couple of typos (predition -> prediction) and a general style fix that was pointed out by Derek when I was having my sliced multithreading patch in review by him.

* | Revert "h264: assembly version of get_cabac for x86_64 with PIC (v4)"Michael Niedermayer2012-04-213-125/+25
| | | | | | | | | | | | This broke compilation on darwin, revert until a better solution is found. This reverts commit a812b599b504b39a8021827da89d5e23fb361cc9.
* | h264: assembly version of get_cabac for x86_64 with PIC (v4)Roland Scheidegger2012-04-213-25/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a hand-optimized assembly version for get_cabac much like the existing one, but it works if the table offsets are RIP-relative. Compared to the non-RIP-relative version this adds 2 lea instructions and it needs one extra register. There is a surprisingly large performance improvement over the c version (more so than the generated assembly seems to suggest) just in get_cabac, I measured roughly 40% faster for get_cabac on a K8. However, overall the difference is not that big, I measured roughly 5% on a test clip on a K8 and a Core2. Hopefully it still compiles on x86 32bit... v2: incorporated feedback from Loren Merritt to avoid rip-relative movs for every table, and got rid of unnecessary @GOTPCREL. v3: apply similar fixes to the the decode_significance functions, and use same macro arguments for non-pic case. v4: prettify inline asm arguments, add a non-fast-cmov version (as I expect the c code to be faster otherwise since both cmov and sbb suck hard on a Prescott, even can't construct the mask with a 64bit shift as that's just as terrible - it's quite difficult to find usable instructions on that chip...). This is tested to work but not on a P4, in theory it _should_ be fast there. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
