[PATCH][RFC] Recognize memcpy/memmove - fix PR53081

2012-06-05 Thread Richard Guenther
This adds memcpy/memmove recognition to loop distribution (and cleans it up some more). Issues are similar to memset and not handled (and I just noticed we generate memset/memcpy even with -fno-builtin ...). Bootstrapped on x86_64-unknown-linux-gnu, testing in progress. Richard. 2012-06-05 Ri
