--- Comment #67 from Julian Seward <jsew...@acm.org> --- Created attachment 144910 --> https://bugs.kde.org/attachment.cgi?id=144910&action=edit Demonstrates misbehaving `vmovdqu8 %ymm7, (%r9){%k5}` I've been testing the patches from comment 58, 59, 60 against the trunk, using Fedora 35 running on a Core i5-1135G7. It passes the tests in the comment 60 patch, but causes regressions in various other tests. I tracked one problem down to an incorrect implementation of 256-bit stores that use a guard register (k1 .. k7). This causes glibc's memset() to misbehave, hence causing --tool=none runs to fail. Testcase is attached. I imagine it's caused by an incorrect translation into IR, but I haven't figured out how that translation is done. -- You are receiving this mail because: You are watching all bug changes.
