The modification only uses the unique part of the synthesis_update function. Pass byte to byte conformance test both on ARMv7 and ARMv8, and the single function performance is similar with original assembly version on different platforms (if not specified, the code is compiled by GCC 4.6): | run 100k times | cortex-a7 | cortex-a9 | cortex-a15 | | use C as the base | (1.2Ghz) | (1.0Ghz) | (1.7Ghz) | | (the smaller the better) | | | | |----------------------------+-----------+-----------+------------| | C | 100% | 100% | 100% | | Neon asm | 15.93% | 17.01% | 12.50% | | Neon inline asm | 27.74% | 31.41% | 14.64% | | Neon intrinsics (GCC 4.8) | 17.84% | 14.10% | 13.84% | | Neon intrinsics (LLVM 3.4) | 16.63% | 14.01% | 12.98% | BUG=3580 R=andrew@webrtc.org Review URL: https://webrtc-codereview.appspot.com/23159004 Patch from Zhongwei Yao <zhongwei.yao@arm.com>. git-svn-id: http://webrtc.googlecode.com/svn/trunk@7586 4adac7df-926f-26a2-2b94-8c16560cd09d
