Loren Merritt	7a1944b907	vf_hqdn3d: x86 asm 13% faster on penryn, 16% on sandybridge, 15% on bulldozer Not simd; a compiler should have generated this, but gcc didn't.	12 years ago
Anton Khirnov	4d7adec8bd	AVOptions: store defaults for INT64 options in int64 union member. Double does not have enough precision to represent all int64 numbers exactly.	12 years ago

Mans Rullgard	5b170c0bea	x86: remove FASTDIV inline asm 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>	12 years ago
Diego Biurrun	66baa45801	configure: Drop fastdiv option 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.	12 years ago
Michael Niedermayer	4b529edff8	deprecate av_parse_cpu_flags This function is problematic in several ways, its also quite unpredictable which flags it ends up turning on Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Mans Rullgard	87fa05a0da	ARM: intmath: use native-size return types for clipping functions This avoids having the compiler redundantly mask the values to the smaller size. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	6c4975eaaf	libavutil: add saturating addition functions Fixed-point audio codecs often use saturating arithmetic, and special instructions for these operations are common. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Mans Rullgard	33de86db2b	dict: move struct AVDictionary definition to dict.c This makes struct AVDictionary fully opaque now that nothing needs to access it directly any more. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	987170cb9d	dict: add av_dict_count() 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>	12 years ago
Mans Rullgard	0d735ca214	ARM: add missing "cc" clobber in av_clipl_int32_arm() Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Mans Rullgard	1c4ab37c38	libavutil: drop offsetof() fallback definition 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>	12 years ago
Mans Rullgard	d913fd1f00	libavutil: drop fallback definitions of INTxx_MIN/MAX 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>	12 years ago

Mans Rullgard	d7a4f8f8b9	Move MASK_ABS macro to libavcodec/mathops.h 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>	12 years ago
Mans Rullgard	070a402b60	x86: move MANGLE() and related macros to libavutil/x86/asm.h These x86-specific macros do not belong in generic code. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	c318626ce2	x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Mans Rullgard	ec9d2c15c1	ARM: use Q/R inline asm operand modifiers only if supported 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>	12 years ago
Mans Rullgard	edd8226795	x86: fix build with nasm 2.08 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.	12 years ago
Mans Rullgard	180d43bc67	x86: use nop cpu directives only if supported 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>	12 years ago
Mans Rullgard	7238265052	x86: fix rNmp macros with nasm For some reason, nasm requires this. No harm done to yasm. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	a3df4781f4	x86: add colons after labels nasm prints a warning if the colon is missing. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	82494835c4	rational: add av_inv_q() returning the inverse of an AVRational This allows simplifying a few expressions. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext 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.	12 years ago
Diego Biurrun	ca844b7be9	x86: Use consistent 3dnowext function and macro name suffixes 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.	12 years ago

Loren Merritt	f8d8fe255d	x86inc: clip num_args to 7 on x86-32. 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>	12 years ago
