-fomit-frame-pointer is broken due to IRA merge. On Linux/ia32, there are
+FAIL: libgomp.fortran/vla7.f90 -O3 -fomit-frame-pointer execution test
+FAIL: libgomp.fortran/vla7.f90 -O3 -fomit-frame-pointer -funroll-all-loops
-finline-functions execution test
+FAIL: libgomp.fortran/vla7.f90 -O3 -fomit-frame-pointer -funroll-loops
execution test
Remove -fomit-frame-pointer, they pass.
