--- Comment #3 from gretay at gcc dot gnu.org --- Thanks a lot for the quick responses! Unfortunately, the frontend patch alone doesn't fix the problem, as Richard pointed out, but it may be needed for other reasons. The tree-sra patch fixes the test failure. If this is the right thing to do, can you please commit these changes? I applied both patches and tested for arm-none-eabi. No regression on qemu. Thank you, Greta
