Subject: remove dependency of wmemmove on wmemcpy direction
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=bac03cdde1137c16b4c194e137310e2748661dcc

remove dependency of wmemmove on wmemcpy direction

unlike the memmove commit, this one should be fine to leave in place.
wmemmove is not performance-critical, and even if it were, it's
already copying whole 32-bit words at a time instead of bytes.
