speed of simple loops on x86_64 using opencc vs gcc

2011-09-07 Thread Steve White
Hi, I run some tests of simple number-crunching loops whenever new architectures and compilers arise. These tests on recent Intel architectures show similar performance between gcc and icc compilers, at full optimization. However a recent test on x86_64 showed the open64 compiler outstripping gc
