--- Comment #10 from James Greenhalgh <jgreenhalgh at gcc dot gnu.org> --- The most striking improvement was in libquantum, for which we saw a 15% performance improvement on Cortex-A72 (3% on cortex-A57) directly attributable to basic block ordering after this patch. Otherwise, I don't have a direct before/after comparison for just Honza's patch across a wider set of benchmarks, but our nightly runs show general improvements in benchmarks from Spec which are sensitive to block reordering after the day of the patch. I don't see any large regressions in this time.
