Sorry for the delay.
No, as safe correctness was the issue I prioritized re-using the
previous solution. I thought it couldn't happen too often, or
this bug would have been noticed before. What indications of
non-pessimization do you require?
For example looking at the impact on gcc.c-torture/compile at -O2 to get a
quick idea. I've attached a patch (originally from Richard S. IIRC) that
preserves the assembly files generated for this directory.
I finally did this, and of the 991 assembly files, there were
(as I expected) no differences for revision 154742 for cris-elf
before/after the patch.
Ok to commit now?
