* vf_hqdn3d: x86 asmLoren Merritt2012-08-26
| | | | | 13% faster on penryn, 16% on sandybridge, 15% on bulldozer Not simd; a compiler should have generated this, but gcc didn't.
* AVOptions: store defaults for INT64 options in int64 union member.Anton Khirnov2012-08-24
| | | | | Double does not have enough precision to represent all int64 numbers exactly.

* x86: remove FASTDIV inline asmMans Rullgard2012-08-22
| | | | | | | | | | | | | | | | | | | GCC 4.3 and later do the right thing with the plain C code. Earlier versions in 32-bit mode generate one extra instruction, needlessly zeroing what would be the high half of the shifted value. At least two gcc configurations miscompile the inline asm in some situations. In 64-bit mode, all gcc versions generate imul r64, r64 followed by shr. On Intel i7 and later, this imul is faster 32-bit mul. On older Intel and all AMD, it is slightly slower. On Atom it is much slower. Considering where the FASTDIV macro is used, any overall negative performance impact of this change should be negligible. If anyone cares, they should file a bug against gcc and get the instruction selection fixed. Signed-off-by: Mans Rullgard <mans@mansr.com>
* configure: Drop fastdiv optionDiego Biurrun2012-08-22
| | | | | | There is no point in having the user disable any fastdiv macros. Besides the condition implementation was broken and only disabled the C implementation, but no platform specific assembly versions.

* 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>

* 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>

* 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.
