https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206990 --- Comment #17 from Mark Millard <markmi@dsl-only.net> --- (In reply to Justin Hibbits from comment #16) I've recently finally updated my powerpc contexts, including 32-bit without so-called red-zone use. It is working so far (G5, G4, and G3 examples for 32-bit and G5 for 64-bit). But not extensively tested yet. There was another, later fix in llvm than has been listed here, again tied to stack operation ordering but not specifically to the no-red-zone requirement. llvm master -r303257 but there was a separate patch for 4.0.0 because the update did not apply. There was a PR33070 to have 4.0.1 updated. -r303257 goes back to 2017-May-17 or so. llvm PR33070 is listed as fixed already. llvm bugzilla 26519 can probably be listed as fully fixed now: the -r303257 related stuff was the last of the fixes for respecting criteria for the ordering of stack operations for 32-bit. Thanks go to Krzysztof Parzyszek for supplying all the fixes involved. --=20 You are receiving this mail because: You are the assignee for the bug.=
