Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	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	54918d0394	libavutil: remove unused av_abort() macro 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
Diego Biurrun	804d7a1aa6	doxygen: Fix function parameter names to match the code	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

Ronald S. Bultje	02ac28229a	eval: fix printing of NaN in eval fate test. This fixes "make fate-eval" on MSVC builds. Without this, the test outputs "-1.#NaN" instead of "nan" on MSVS 2010.	12 years ago

Samuel Pitoiset	983db9b2b4	xtea: Make the count parameter match the documentation Previously it was interpreted as number of bytes, while the documentation stated that it was the number of 8 byte blocks. This makes it behave similarly to the existing AES code. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
