--- Comment #2 from avieira at gcc dot gnu.org ---
I am observing some regressions for arm-none-eabi on a Cortex-M0+ for a popular
embedded benchmark following this patch.
I believe register pressure might also be the root cause of this given the
significant increase of loads and registers from and to the stack. Though I
need to have a better look.
Passing the option -fno-code-hoisting brings the performance numbers back up.
