--- Comment #1 from Bernd Schmidt <bernds at gcc dot gnu.org> ---
I'm tempted to classify this as unsupported. The testcase reserves edx, and the
alloca call includes a division operation which requires edx. Without
optimization, it remains until register allocation.
Global registers are somewhat fragile, and I think it's not worth it trying to
fix this. I'd put this at P4 at most.
