Diego Biurrun	b6649ab503	cosmetics: Remove unnecessary extern keywords from function declarations	12 years ago

Justin Ruggles	95d01c3f1c	x86: lavr: use the x86inc.asm automatic stack alignment in mixing functions ... CC:libav-stable@libav.org	12 years ago
Ronald S. Bultje	7a9e65acee	x86: lavr: fix stack allocation for 7 and 8 channel downmixing on x86-32 ... Fixes crashes on Win32 and stack overruns on x86-32 in general.	12 years ago
Diego Biurrun	2b479bcab0	build: Drop AVX assembly ifdefs ... An assembler able to cope with AVX instructions is now required.	12 years ago
Diego Biurrun	4b60fac419	x86: PALIGNR: port to cpuflags	12 years ago
Diego Biurrun	352e18b766	x86: avresample: Add missing colons to assembly labels ... YASM accepts labels without colons, but NASM issues warnings.	12 years ago
Diego Biurrun	04581c8c77	x86: yasm: Use complete source path for macro helper %includes ... This is more consistent with the way we handle C #includes and it simplifies the build system.	12 years ago
Diego Biurrun	6860b4081d	x86: include x86inc.asm in x86util.asm ... This is necessary to allow refactoring some x86util macros with cpuflags.	12 years ago
Justin Ruggles	10e645e9cb	lavr: handle clipping in the float to s32 conversion ... We cannot clip to INT_MAX because that value cannot be exactly represented by a float value and ends up overflowing during conversion anyway. We need to use a slightly smaller float value, which ends up with slightly inaccurate results for samples which clip or nearly clip, but it is close enough. Using doubles as intermediates in the conversion would be more accurate, but it takes about twice as much time. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 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.	12 years ago
Diego Biurrun	17337f54c0	x86: Split inline and external assembly #ifdefs	12 years ago
Diego Biurrun	a886b279a0	x86: cosmetics: Comment some #endifs for better readability	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
Justin Ruggles	e9da9a3111	lavr: x86: improve non-SSE4 version of S16_TO_S32_SX macro ... Removes a false dependency on existing contents of the 2nd dst register, giving better performance for OOE.	12 years ago
Justin Ruggles	2f096bb10e	lavr: add x86-optimized mixing functions ... Adds optimized functions for mixing 3 through 8 input channels to 1 and 2 output channels in fltp or s16p format with flt coeffs.	12 years ago

Justin Ruggles	acd9948e74	lavr: x86: fix ff_conv_fltp_to_flt_6ch function prototypes ... Changed to match the number of parameters in conv_func_interleave(), which is how they are called. The change isn't strictly necessary because the 4th parameter is not used, but the code is clearer if they match.	13 years ago
