andrew@webrtc.org	fdbe1442c5	Use C functions in aec for MIPS ... With GCC 4.9, the MIPS NDK toolchain has been changed to only support 16 spregs by default - the even-numbered ones. This has been changed to support the R6 MIPS architecture. While the old behaviour could be restored by adding "-modd-spreg", this would come with a performance hit because the kernel would emulate odd-numbered spregs and missing R2 instructions. As a result of this change, the functions removed in this CL no longer compile as there are no longer enough spregs for the compiler to assign. So we are removing these functions and they will use the C implementation until the MIPS code is rewritten.

andrew@webrtc.org	c0907eff42	MIPS optimizations for AEC audio processing module ... The resulting output streams obtained by testing with audioproc test application are bit-exact with generic C code output streams. Performance gain achieved: - mips32 ~ 17% - mips32r2 ~ 20% - mipsdsp & mipsdspr2 ~ 21% R=andrew@webrtc.org Review URL: https://webrtc-codereview.appspot.com/7359004 Patch from Ljubomir Papuga <lpapuga@mips.com>. git-svn-id: http://webrtc.googlecode.com/svn/trunk@5591 4adac7df-926f-26a2-2b94-8c16560cd09d	2014-02-21 00:13:31 +00:00
