Lynne	469cd8d7fa	aacdec: convert to lavu/tx and support fixed-point 960-sample decoding This patch replaces the transform used in AAC with lavu/tx and removes the limitation on only being able to decode 960-sample files with the float decoder. This commit also removes a whole bunch of unnecessary and slow lifting steps the decoder did to compensate for the poor accuracy of the old integer transformation code. Overall float decoder speedup on Zen 3 for 64kbps: 32%	2 years ago
Andreas Rheinhardt	f3c197b129	Include attributes.h directly Some files currently rely on libavutil/cpu.h to include it for them; yet said file won't use include it any more after the currently deprecated functions are removed, so include attributes.h directly.

Shiyou Yin	44699db6db	avcodec/mips: Fix register constraint error reported by clang. Clang report following error in aacsbr_mips.c,ac3dsp_mips.c and aacdec_mips.c: "couldn't allocate output register for constraint 'r'" Use 'f' constraint for float variable.

Rosen Penev	875ba23333	avcodec/aacdec: fix compilation under soft float MIPS Place HAVE_MIPSFPU further up so that functions that use floating point ASM are defined away. Otherwise compilation failures result when soft float in enabled on the toolchain. Signed-off-by: Rosen Penev <rosenp@gmail.com>	5 years ago
Shiyou Yin	de5543d8d4	avcodec/mips: Fix a warnning of indentation not reflect the block structure. The indentation of code dose not reflect the if block structure in 'apply_ltp_mips', and this will generate a warnning when build with '-Wall' or '-Wmisleading-indentation'.

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.
