James Cowgill	157d6f0d5b	mips: port optimizations to mips n64 This mainly consists of replacing all the pointer arithmatic 'addiu' instructions with PTR_ADDIU which will handle the differences in pointer sizes when compiled on 64 bit mips systems. The header asmdefs.h contains the PTR_ macros which expend to the correct mips instructions to manipulate registers containing pointers.

James Cowgill	d6f66aec50	mips/fft: remove some useless assembly Remove some assembly that the compiler can easily handle optimally on its own. GCC produces almost identical assembly.

Nedeljko Babic	271f95940b	libavcodec/mips: fix for mips optimized fp fft with hard coded tables disabled Floating point FFT (nips optimized) breaks when hard coded tables are not enabled because MIPS optimization of floating point FFT uses only ff_init_ff_cos_tabs(16) which is not enabled by default in that case. This patch is fixing it. Signed-off-by: Nedeljko Babic <nbabic@mips.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Nedeljko Babic	b3fdfc8c4e	Optimization of AC3 floating point decoder for MIPS FFT in MIPS implementation is working iteratively instead of "recursively" calling functions for smaller FFT sizes. Some of DSP and format convert utils functions are also optimized.
