[PATCH] benchtests: Build ffs and ffsl benchtests with -fno-builtin
- From: Will Newton <will dot newton at linaro dot org>
- To: libc-alpha at sourceware dot org
- Date: Tue, 1 Apr 2014 11:24:01 +0100
- Subject: [PATCH] benchtests: Build ffs and ffsl benchtests with -fno-builtin
- Authentication-results: sourceware.org; auth=none
Without this flag it is possible that the compiler will optimize
away the calls to ffs/ffsll.
ChangeLog:
2014-03-31 Will Newton <will.newton@linaro.org>
* benchtests/Makefile (CFLAGS-bench-ffs.c): Add
-fno-builtin. (CFLAGS-bench-ffsll.c): Likewise.
