Re: [PATCH] Exploiting dual mode operation, implementation.



There certainly are other parts in the compiler where it can be a problem, though most passes, AFAICT, do handle PARALLELs. But gcse PRE does not.

I'm pretty sure this isn't true anymore. The comments claim it is, but the code shows otherwise.

Certainly, cprop and friends don't deal with PARALLEL's, but PRE does.

See hash_scan_insn and mark_oprs_set
