* lavu/riscv: byte-swap operationsRémi Denis-Courmont2022-09-131-0/+2
| | | | | | | | | | | | | If the target supports the Basic bit-manipulation (Zbb) extension, then the REV8 instruction is available to reverse byte order. Note that this instruction only exists at the "XLEN" register size, so we need to right shift the result down to the data width. If Zbb is not supported, then this patchset does nothing. Support for run-time detection is left for the future. Currently, there are no bits in auxv/ELF HWCAP for Z-extensions, so there are no clean ways to do this.
* Fix compile error on bfin.Bernd Kuhls2014-08-051-2/+0
| | | | | | | | | | | | | | | | | | After the removal of all Blackfin architecture optimizations in http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=b55d3bbeed375f7b74442c4dd274d116a3e3d2e1 some includes were left behind leading to a compile error: CC libavformat/adtsenc.o In file included from ./libavcodec/get_bits.h:35, from ./libavcodec/ac3_parser.h:27, from libavformat/ac3dec.c:23: ./libavcodec/mathops.h:43:29: error: bfin/mathops.h: No such file or directory This compile error was found by buildroot autobuild system: http://autobuild.buildroot.net/results/ae0/ae056f267e907091d09d2a1546d6f1ae02fa23b9/ Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| * bswap: make generic implementation more compiler-friendlyMans Rullgard2011-12-121-11/+2
| | | | | | | | | | | | | | | | With these changes, gcc 4.5 and later recognise it as a bswap and use the proper instructions on ARM and x86. On x86, the 16-bit bswap is recognised from gcc 4.1. Signed-off-by: Mans Rullgard <mans@mansr.com>

* bswap: change ME to NE in macro namesMåns Rullgård2010-07-101-24/+24
| | | | | | | Other parts of FFmpeg use NE (native endian) rather than ME (machine). This makes it consistent. Originally committed as revision 24169 to svn://svn.ffmpeg.org/ffmpeg/trunk

* bswap: add macros to byteswap constantsMåns Rullgård2010-04-291-0/+17
| | | | | | | | | | | The normal byteswap functions might use inline asm which is suboptimal with constants (and cannot be used in static initialisers), so special macros for constants only is needed. We should not rely on the gcc __builtin_constant_p() test since it is not always available. Originally committed as revision 22990 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-201-1/+1
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Replace many includes of libavutil/common.h with what is actually neededMåns Rullgård2010-03-091-1/+1

* Convert asm keyword into __asm__.Diego Pettenò2008-10-161-10/+10
| | | | | | | | | | | | | Neither the asm() nor the __asm__() keyword is part of the C99 standard, but while GCC accepts the former in C89 syntax, it is not accepted in C99 unless GNU extensions are turned on (with -fasm). The latter form is accepted in any syntax as an extension (without requiring further command-line options). Sun Studio C99 compiler also does not accept asm() while accepting __asm__(), albeit reporting warnings that it's not valid C99 syntax.

* Globally rename the header inclusion guard names.Stefano Sabatini2008-08-311-3/+3
| | | | | | | | | 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
