Optimize x86-64 strlen for SSE4.2. The SSE4.2 implementation is used in the DSO only. The patch also adds some infrastructure to be used in similar code later one. 2009-06-05 18:32:00 +00:00			`gen-as-const-headers += ifunc-defines.sym`

SSSE3 strcpy/stpcpy for x86-64 This patch adds SSSE3 strcpy/stpcpy. I got up to 4X speed up on Core 2 and Core i7. I disabled it on Atom since SSSE3 version is slower for shorter (<64byte) data. 2009-07-02 10:39:03 +00:00			`sysdep_routines += stpncpy-c strncpy-c strncmp-c`
