| * avutil: add av_parse_cpu_flags() functionMans Rullgard2012-04-25
| | | | | | | | | | | | | | This moves the cpu flag parsing code from avconv to avutil so it can be accessed elsewhere. Signed-off-by: Mans Rullgard <mans@mansr.com>

| * ARM: allow runtime masking of CPU featuresMans Rullgard2012-04-22
| | | | | | | | | | | | | | 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>

| * remove iwmmxt optimizationsJanne Grunau2012-03-12
| | | | | | | | | | | | 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.

* | Detect and check for CMOV.Reimar Döffinger2012-02-12
| | | | | | | | | | | | | | | | | | Some MMX-only CPUs do not have support for CMOV. All SSE/MMX2 CPUs should be fine, thus no check was added to those functions.

| * Add a CPU flag for the Atom processor.Justin Ruggles2011-03-22
| | | | | | | | | | | | | | The Atom has SSSE3 support, which is useful in many cases, but sometimes the SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally faster on other processors supporting SSSE3. This flag allows for selectively disabling certain SSSE3 functions on the Atom.
