Rich Felker	1701e4f3d4	reenable word-at-at-time copying in memmove ... before restrict was added, memove called memcpy for forward copies and used a byte-at-a-time loop for reverse copies. this was changed to avoid invoking UB now that memcpy has an undefined copying order, making memmove considerably slower. performance is still rather bad, so I'll be adding asm soon.	2012-09-10 18:16:11 -04:00
Rich Felker	594318fd3d	remove dependency of memmove on memcpy direction ... this commit introduces a performance regression in many uses of memmove, which will need to be addressed before the next release. i'm making it as a temporary measure so that the restrict patch can be committed without invoking undefined behavior when memmove calls memcpy with overlapping regions.	2012-09-06 20:25:48 -04:00
