Diego Biurrun b78b10c4b7 avutil: Move internal CPU detection function declarations to private header 2013-08-28 23:54:14 +02:00
Anton Khirnov 2a6eaeaa85 Move get_logical_cpus() from lavc/pthread to lavu/cpu. 
It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

Janne Grunau 8f5587c3d0 cpu.h: define AV_CPU_FLAG_MMX2 for libavutil major 52 2012-11-16 15:04:48 +01:00
Diego Biurrun 239fdf1b4a x86: build: replace mmx2 by mmxext 
Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

Mans Rullgard 3527a73933 avutil: add av_parse_cpu_flags() function 
This moves the cpu flag parsing code from avconv to avutil so
it can be accessed elsewhere.

Mans Rullgard d526c5338d ARM: allow runtime masking of CPU features 
This allows masking CPU features with the -cpuflags avconv option
which is useful for testing different optimisations without rebuilding.

Janne Grunau 363bd1c62c remove iwmmxt optimizations 
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.

Diego Biurrun 153382e1b6 multiple inclusion guard cleanup 
Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

Justin Ruggles eba586b0d9 Add a CPU flag for the Atom processor. 
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.

Måns Rullgård 9275438a19 Clean up av_get_cpu_flag() 
Instead of defining functions in per-arch header files included
by the main cpu.c, define them normally and call them from the
generic one.
