Subject: Allow adding of arbitrary code to benchmark tests
X-Git-Tag: glibc-2.18~483
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3775a8bc2d2e0c29c8a7e673f5f42537ced2b3c7;p=thirdparty%2Fglibc.git

Allow adding of arbitrary code to benchmark tests

This allows us to define custom functions in C code files and
benchmark scenarios rather than just functions.  The main current use
of this is to separate the slow and fast path benchmarks for math
functions.
