Subject: Further simplify power6 wordcopy by removing switch statements.
X-Git-Tag: glibc-2.16-tps~596
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6b652f46c3935088082bb5870b6fd9edbaa92125;p=thirdparty%2Fglibc.git

Further simplify power6 wordcopy by removing switch statements.

This fix replaces switch statements that contain individual
[fwd|bwd]_align_merge (<constant>) calls with a single [fwd|bwd]_align_merge
(align) call.
