I'm interested too. :-) FWIW, when I did the transition on SPARC, I compared
the assembly code generated for all testcases in gcc.c-torture/compile at -O2;
IIRC there were a few regressions related to delay-slot filling too, but I think
I eliminated them with a couple of patches (probably to reorg.c).
