--- Comment #8 from Rin Okuyama <rin at NetBSD dot org> --- (In reply to Oleg Endo from comment #7) Hi Oleg. Thank you very much for your great work! I've tested your patch with GCC 10.4.0 in this weekend, and it perfectly worked: - testcase attached to comment #0 compiled correctly - full regression tests on NetBSD/shle-current built by patched GCC successfully completed without any regression (compared with system built by GCC with that peephole optimization removed) - some 3rd party softwares (including perl 5.36.0, ruby 3.10.10, zsh 5.9, ...) self-built on shle host by GCC of same code base Let me thank you again, Oleg! rin
