Bug ID: 113175 Summary: [14 Regression] MMIX: testsuite/std/ranges/iota/max_size_type.cc 5x times slower Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: hp at gcc dot gnu.org Target Milestone: --- Host: x86_64-linux-gnu Target: mmix-knuth-mmixware (Perhaps a "[13 Regression]" as well - haven't checked.) I ran the testsuite for mmix-knuth-mmixware (a 64-bit newlib cross) and found that testsuite/std/ranges/iota/max_size_type.cc times out, despite the timeout-factor increased by a factor 4 (from 360 seconds to 1440 seconds) in r12-2799-ge9b639c4b53221. For a tree at r12-2797-g307e0d40367996 running this test takes 11:43.61 (mm:ss) wall-clock time and now at r14-6859-gd1eacedc6d9b it takes 58:45.78 (on one and the same host and same session within the same hour; no host-side changes and the test itself apparently hasn't changed significantly). I haven't checked whether this affects other targets, but if so, a 5x performance regression should have been picked up by other testers, thus I'm starting with "target" until firther investigated.
