--- Comment #3 from Paul-Antoine Arras <parras at gcc dot gnu.org> --- (In reply to Jeffrey A. Law from comment #2) > Paul -- have you run your patch on any design? And if so what did you run > and what was the performance delta before/after? Thanks for your input, Jeff! Unfortunately, no, I don't have any actual hardware to test on. All the data I have is dynamic instruction counts (DIC) from user-mode QEMU runs of SPEC benchmarks. On 554.roms, my patch yields a reduction in DIC of 7.57% within the basic block.
