[PATCH] D30759: With PIE on x86_64, keep hot local arrays on the stack

There's also another possibility: you could make the register allocator prefer to spill some other register which isn't on the critical path.  Not sure if that's practical for the loops you care about.

That said, your possibility (a) seems reasonable.
