* x86: use raw opcode for xgetbv instructionMans Rullgard2011-02-22
| | | | | | | | | | | This allows the CPU detection to work with assemblers not supporting the xgetbv mnemonic. These include clang and some BSD versions. All AVX code will be written for yasm, where the main assembler is not involved. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit ef6695387522fc783105ac187c84beaa284e7cff)
* x86: check for AVX supportMans Rullgard2011-02-20
| | | | | | | This adds configure and runtime checks for AVX support on x86 CPUs. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 87f1355f9b4fc11414d0e6a91404203c2745f89f)
* Force inlining of avutil common routinesJason Garrett-Glaser2011-02-18
| | | | | | | On some versions of gcc, these weren't always getting inlined due to hitting the inline cap limit in some files. This is generally bad, as most of these functions are smaller inlined than not. (cherry picked from commit eb3755a5aa65da685d81399cfae4bd35e4a178b6)
* lavf, lavu: bump minor versions and add an APIChanges entry for av_ prefixesAnton Khirnov2011-02-18

* Deprecate parse_date() in favor of av_parse_time().Stefano Sabatini2011-02-18
| | | | | | | | | The new av_parse_time() is created in libavutil/parseutils.h, all the internal functions used by parse_date are moved to libavutil/parseutils.c and made static. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit f6c7375a175ac649558aefab14f3895b2cb469aa)

* Rename attribute_used to av_used and move it to attributes.hMans Rullgard2011-01-31
| | | | | | | This is consistent with most of the other attribute macros. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 365e3c7878e4e821d5dec922d2d51f92ce13f926)
