Re: [PATCH, PR61605, 2/2] Use fuse-caller-save info in pass_cprop_hardreg

Eric,

this patch is the second half of the fix for PR61605.

It make sure in pass_cprop_hardreg that, if available we use the
call-specific information provided by fuse-caller-save, rather than the
generic regs_invalidated_by_call info.

The 2 patches together allow an insn to removed from the
gcc.target/i386/fuse-caller-save.c testcase, which is updated
accordingly in this patch.

Bootstrapped and reg-tested on x86_64.

OK for trunk?

Thanks,
- Tom
