Michael Niedermayer	b3ab281027	avcodec/x86/cabac: workaround llvm 4.2.1 bug x86_64 is affected by this too Fixes Ticket2156 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Ronald S. Bultje	1768e43ceb	vorbisdsp: change block_size type from int to intptr_t. This saves one instruction in the x86-64 assembly.	12 years ago
Ronald S. Bultje	8a4f26206d	dsputil: remove butterflies_float_interleave. The function is unused.	12 years ago
Mans Rullgard	0b711ca3f3	dsputil: drop non-compliant "fast" qpel mc functions Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Ronald S. Bultje	fef906c77c	Move vorbis_inverse_coupling from dsputil to vorbisdspcontext. Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.	12 years ago
Ronald S. Bultje	aeaf268e52	vp3: integrate clear_blocks with idct of previous block. This is identical to what e.g. vp8 does, and prevents the function call overhead (plus dependency on dsputil for this particular function). Arm asm updated by Janne Grunau <janne-libav@jannau.net>.

Michael Niedermayer	9cb3c1a4d9	x86/dirac: fix asm on win64 This could also be fixed by changing the argument type if someone prefers that and wants to change it ... Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	30981a966f	lavc: split snow and dirac DWTs There is only about 4 lines of common code, so it alot cleaner when seperated. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	9cb887ed37	dsputil_mmx: fix pointer type for emulated_edge_mc_func() Found-by: ubitux Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	3e15775333	x86/ac3dsp_init: try to workaround ICC failure. The asm code is not valid for older compilers as it uses too many operands, ICC on x86_32 seems affected by this. This patch disables the affected code for ICC on x86_32 and should make it compileable again. A better fix would be to use fewer operands or to change this code to yasm, later is being worked on AFAIK so this is a temporary solution.
