Diego Biurrun	1f6d86991f	x86: Add YASM implementations of cpuid and xgetbv from x264 This allows detecting CPU features with builds that have neither gcc inline assembly nor the right compiler intrinsics enabled.	12 years ago

Anton Khirnov	cd15b7c03d	samplefmt: make av_samples_alloc() initialize the data to silence. Right now the buffer is zeroed, which does not represent silence for U8(P).	12 years ago

Mans Rullgard	05e209c04c	Allow use of strncpy() There are cases where strncpy() does exactly what is required. A blanket ban forces more convoluted solutions to be used in those cases and has been a cause of bugs. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Mans Rullgard	51a15ed740	ARM: use numeric ID for Tag_ABI_align_preserved Some old assemblers still in use do not support named tags. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	1ca3b62b10	ARM: bswap: drop armcc version of av_bswap16() This function causes several versions of armcc to miscompile code, and the performance impact is small. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	5e826fd65e	ARM: set Tag_ABI_align_preserved in all asm files All our ARM asm preserves alignment so setting this attribute in a common location is simpler. This removes numerous warnings when linking with armcc. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	7bda4ed780	ARM: fix Thumb PIC on Apple LDR with register offset and PC as base register is not available in the Thumb instruction set so the addition must be done separately. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	11d4e92ed9	avformat: Remove non-compiling and/or silly commented-out printf/av_log statements	12 years ago
Mans Rullgard	8995d34972	ARM: use 2-operand syntax for ADD Rd, PC in Apple PIC code The Apple assembler refuses to assemble the 3-operand form in Thumb2 even though it is valid syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	cdb7db5acd	ARM: align PIC offset pools to 4 bytes When building Thumb2 code, the end of a function, where the PIC offsets are placed, need not be aligned. Although the values are only accessed with instructions allowing unaligned addresses, keeping them aligned is preferable. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	a27a690fac	ARM: swap source operands in some add instructions This allows using a 16-bit opcode when generating Thumb2 code. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	13 years ago
Justin Ruggles	7327525997	x86: float_dsp: fix ff_vector_fmac_scalar_avx() on Win64 The SWAP macro does not work for explicit xmm/ymm usage, so instead just move the scalar value from xmm2 to xmm0.	13 years ago

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.	13 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.	13 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>	13 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.	13 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>	13 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>	13 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>	13 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>	13 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.
