* intreadwrite: Add AV_COPYxxU macros for copying to/from unaligned addressesDiego Biurrun2012-10-23

* intreadwrite.h: fix AV_RL32/AV_RB32 signedness.Uoti Urpala2011-06-16
| | | | | | | | | The output type of the AV_RL32/AV_RB32 macros was signed int. The resulting overflow broke at least some ASF streams with large timestamps. Fix by adding a cast to uint32_t. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* intreadwrite: ensure arch-specific versions are always used if definedMåns Rullgård2009-08-16
| | | | | | | | | 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

* Check for __attribute__((packed)) supportMåns Rullgård2009-07-17
| | | | | | Not all compilers claiming to be gcc support this attribute. Originally committed as revision 19453 to svn://svn.ffmpeg.org/ffmpeg/trunk
* MIPS: inline asm for intreadwrite.hMåns Rullgård2009-05-28
| | | | Originally committed as revision 18980 to svn://svn.ffmpeg.org/ffmpeg/trunk
* PPC asm for AV_RL*()Måns Rullgård2009-04-18
| | | | | | | | | | | | 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 Rullgård2009-04-18
| | | | | | | | | | | | | | | 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 Rullgård2009-04-18
| | | | | | | | 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
* Change semantic of CONFIG_*, HAVE_* and ARCH_*.Aurelien Jacobs2009-01-13

* Globally rename the header inclusion guard names.Stefano Sabatini2008-08-31
| | | | | | | | | Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
