Mans Rullgard	fab0a8b2c6	libm: add fallbacks for various single-precision functions Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Ronald S. Bultje	183b1c2268	configure: Check for the math function rint Add a fallback implementation if it doesn't exist. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	46df708b45	libm: Provide fallback definitions for isnan() and isinf() Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	153335625c	libm: provide fallback definition for cbrtf() using powf() This adds a fallback for cbrtf() using powf(x, 1/3). Since powf() with a non-integer exponent requires a non-negative base, special handling of negative inputs is needed. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Nedeljko Babic	3827a86eac	Optimization of AMR NB and WB decoders for MIPS AMR NB and WB decoders are optimized for MIPS architecture. Appropriate Makefiles are changed accordingly. Cnfigure script is changed in order to support optimizations. Optimizations are enabled by default when compiling is done for mips architecture. Appropriate cflags are automatically set. Support for several mips CPUs is added in configure script. New ffmpeg options are added for disabling optimizations. The FFMPEG option --disable-mipsfpu disables MIPS floating point optimizations. The FFMPEG option --disable-mips32r2 disables MIPS32R2 optimizations. The FFMPEG option --disable-mipsdspr1 disables MIPS DSP ASE R1 optimizations. The FFMPEG option --disable-mipsdspr2 disables MIPS DSP ASE R2 optimizations.

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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.

Måns Rullgård	297bfb2fe6	libm.h needs attributes.h Originally committed as revision 22405 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	335ee1aadd	Move libm replacements to new header libm.h ffmpeg.c uses lrintf(), which is missing on some systems. Previously it picked up the replacement via libavutil/internal.h due to HAVE_AV_CONFIG_H being erroneously defined. Moving these replacements to a separate header enables ffmpeg.c to use them without being exposed to internal interfaces. This use of a non-public header is justified by the header in question not being part of the internal interface either. It should rather be considered as part of the build system, which is shared between the libraries and the applications. This header cannot be installed since the tested conditions depend on the compiler. Originally committed as revision 22399 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
