Law <law at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |law at gcc dot gnu.org --- Comment #1 from Jeffrey A. Law <law at gcc dot gnu.org> --- Dunno if it's relevant. But after Mark W's adjustment to the switch lowering code bootstrap & regression testing times for most targets in my tester jumped significantly (though presumably his risc-v times improved significantly). These are bootstraps & regression tests in QEMU emulated environments, so they're not a great measure of real performance. But they likely do point out that we probably have more sensitivity to these issues than is perhaps obvious and riscv is quite possibly an outlier behavior wise. mips64el-linux-gnu 10hrs -> 23hrs hppa-linux-gnu 10hrs -> 20hrs s390x-linux-gnu 11hrs -> 19hrs And so-on. I don't have a breakdown of where the time is spent (ie, bootstrapping vs testsuite). Finally while the doubing in times sucks, it just brings is back to where we were in Nov 2024 before your work went in. So it's not really a regression in my mind.
