* intreadwrite: ensure arch-specific versions are always used if definedMåns Rullgård2009-08-161-8/+114
| | | | | | | | | The per-arch headers can define any combination of B/L/N variants. This ensures that whatever is defined in an arch header gets used for all equivalents not defined there. E.g. on a little-endian machine, AV_RN and AV_RL should give the same code. Originally committed as revision 19658 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | Instead, #include config.h at the top of common.h so that av_always_inline does not get doubly defined. Originally committed as revision 19553 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Do not throw compiler error if asm code needs alignment, but we do not knowRamiro Polla2009-07-091-2/+0

* PPC: check for x-form asm constraint supportMåns Rullgård2009-04-181-0/+4
| | | | Originally committed as revision 18606 to svn://svn.ffmpeg.org/ffmpeg/trunk
* PPC asm for AV_RL*()Måns Rullgård2009-04-182-0/+106
| | | | | | | | | | | | PPC is normally big endian but has special little endian load/store instructions. Using these avoids a separate byteswap. This makes the vorbis decoder about 5% faster. Not much else uses little-endian read/write extensively. GCC generates horrible PPC code for the default AV_[RW]B64 (which uses a packed struct), so we override it with a plain pointer cast. Originally committed as revision 18602 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ARM asm for AV_RN*()Måns Rullgård2009-04-182-0/+81
| | | | | | | | | | | | | | | 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
* Reorganise intreadwrite.hMåns Rullgård2009-04-181-72/+141
| | | | | | | | This changes intreadwrite.h to support per-arch implementations of the various macros allowing us to take advantage of special instructions or other properties the compiler does not know about. Originally committed as revision 18600 to svn://svn.ffmpeg.org/ffmpeg/trunk
