--- Comment #16 from Bernd Schmidt <bernds at gcc dot gnu.org> --- I retested again with a few different combinations of things. With an older gdb, I can still reproduce the issue that sra-1 becomes UNSUPPORTED (presumably through a gdb crash). With gdb-7.12 installed the patch now causes sra-1.c to fail (apparently a value becomes optimized out). If we consider the guality testsuite in some way meaningful we still can't apply this patch. Also, Vlad's reasoning for waiting until gcc-7 last time now holds for waiting until gcc-8.
