Hello! These two tests fix PR target/63847 [1], where x87 excess precision causes testcase to fail. The problem was triggered by -fpic, please see the PR for analysis.
The patch adds -ffloat-store for 32bit x86 target, a standard and well tested solution for this problem. 2014-11-22 Uros Bizjak <ubiz...@gmail.com> PR target/63847 * c-c++-common/cilk-plus/AN/builtin_fn_custom.c: Add -ffloat-store for 32bit x86 targets. * c-c++-common/cilk-plus/AN/builtin_fn_mutating.c: Ditto. The patch was tested on x86_64-linux-gnu/-m32 {,-fpic}. OK for mainline? [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63847 Uros.
