Subject: Benchtests: Add benchtests for __memcmpeq
X-Git-Tag: glibc-2.35~387
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cf3acd774f4c11e90cdc28192d69c60e2c02a004;p=platform%2Fupstream%2Fglibc.git

Benchtests: Add benchtests for __memcmpeq

No bug. This commit adds __memcmpeq benchmarks. The benchmarks just
use the existing ones in memcmp. This will be useful for testing
implementations of __memcmpeq that do not just alias memcmp.
