* ARM: intmath: use native-size return types for clipping functionsMans Rullgard2012-08-13
| | | | | | | This avoids having the compiler redundantly mask the values to the smaller size. Signed-off-by: Mans Rullgard <mans@mansr.com>
* libavutil: add saturating addition functionsMans Rullgard2012-08-13
| | | | | | | Fixed-point audio codecs often use saturating arithmetic, and special instructions for these operations are common. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dict: move struct AVDictionary definition to dict.cMans Rullgard2012-08-10
| | | | | | | This makes struct AVDictionary fully opaque now that nothing needs to access it directly any more. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dict: add av_dict_count()Mans Rullgard2012-08-10
| | | | | | | | This adds a function to retrieve the number of entries in a dictionary and updates the places directly accessing what should be an opaque struct to use this new function instead. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: add missing "cc" clobber in av_clipl_int32_arm()Mans Rullgard2012-08-10

* libavutil: remove unused av_abort() macroMans Rullgard2012-08-09

* libavutil: drop offsetof() fallback definitionMans Rullgard2012-08-09
| | | | | | | | | The only compiler I have that does not define the standard offsetof() macro is "Bruce's C Compiler", a simple compiler for producing 8/16-bit 8086 code, usually for use in early stages of PC booting. Signed-off-by: Mans Rullgard <mans@mansr.com>
* libavutil: drop fallback definitions of INTxx_MIN/MAXMans Rullgard2012-08-09
| | | | | | | This list is incomplete (we also use UINT16_MAX), so there does not appear to be any system we care about that needs these. Signed-off-by: Mans Rullgard <mans@mansr.com>
* doxygen: Fix function parameter names to match the codeDiego Biurrun2012-08-09

* Move MASK_ABS macro to libavcodec/mathops.hMans Rullgard2012-08-09
| | | | | | | | | | | | This macro is only used in two places, both in libavcodec, so this is a more sensible place for it. Two small tweaks to the macro are made: - removing the trailing semicolon - dropping unnecessary 'volatile' from the x86 asm Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: move MANGLE() and related macros to libavutil/x86/asm.hMans Rullgard2012-08-09
| | | | | | These x86-specific macros do not belong in generic code. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.hMans Rullgard2012-08-09
| | | | | | | This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: use Q/R inline asm operand modifiers only if supportedMans Rullgard2012-08-07
| | | | | | | | | | Some compilers do not support the Q/R modifiers used to access the low/high parts of a 64-bit register pair. Check for this and disable all uses of it when not supported. Fixes bug #337. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: fix build with nasm 2.08Mans Rullgard2012-08-07
| | | | | | | | It appears that something goes wrong in old nasm versions when the %+ operator is used in the last argument of a macro invocation and this argument is tested with %ifdef within the macro. This patch rearranges the macro arguments such that the %+ operator is never used in the last argument.
* x86: use nop cpu directives only if supportedMans Rullgard2012-08-07
| | | | | | | nasm does not support 'CPU foonop' directives. This adds a configure test for the directive and uses it only if supported. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: fix rNmp macros with nasmMans Rullgard2012-08-07
| | | | | | For some reason, nasm requires this. No harm done to yasm. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: add colons after labelsMans Rullgard2012-08-07
| | | | | | nasm prints a warning if the colon is missing. Signed-off-by: Mans Rullgard <mans@mansr.com>
* rational: add av_inv_q() returning the inverse of an AVRationalMans Rullgard2012-08-05
| | | | | | This allows simplifying a few expressions. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: build: replace mmx2 by mmxextDiego Biurrun2012-08-03
| | | | | | | Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.
* x86: Use consistent 3dnowext function and macro name suffixesDiego Biurrun2012-08-03
| | | | | | Currently there is a wild mix of 3dn2/3dnow2/3dnowext. Switching to "3dnowext", which is a more common name of the CPU flag, as reported e.g. by the Linux kernel, unifies this.
* x86inc: clip num_args to 7 on x86-32.Loren Merritt2012-07-28
| | | | | | | | This allows us to unconditionally set the cglobal num_args parameter to a bigger value, thus making writing yasm code even easier than before. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* eval: fix printing of NaN in eval fate test.Ronald S. Bultje2012-07-26
| | | | | This fixes "make fate-eval" on MSVC builds. Without this, the test outputs "-1.#NaN" instead of "nan" on MSVS 2010.

* xtea: Make the count parameter match the documentationSamuel Pitoiset2012-07-05
