https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65647 --- Comment #9 from Jeffrey A. Law --- Either soft or softfp will trigger the failure. Given that it's just a compile test, rather than link & run test, can we just add a -mfloat-abi=soft to the test and avoid the dg-skip-if?

Could somebody please confirm which it should be and patch the testcase on both branches?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65647 Yvan Roux changed: What|Removed |Added CC||yroux at gcc dot gnu.org --- Comment #4 from Yvan Roux --- I was about to report the same issue which occurs during the build of videolan x264 build. Vlad patch fixes the issue on trunk, but with that testcase the problem is also present in 4.9 branch (it occurs this time in ARM mode on armv6 architecture). To be backported on 4.9 the rematerialization code as to be removed from the patch, I'll submit the patch on the mailing list. command line to reproduce the problem: cc1 -O3 -marm -march=armv6 -std=c99 a.c
