--- Comment #18 from Tobias Burnus <burnus at gcc dot gnu.org> --- POST SCRIPT / STATUS UPDATE (This PR remains FIXED) (In reply to Tobias Burnus from comment #16) > > I unfortunately missed in my the LLVM patch that '.rodata' implies flags and > > messed up the check. Should by fixed by: https://reviews.llvm.org/D94072 > > Now merged to LLVM 12/trunk (see ↑ or next link); for LLVM 11 backporting, > see: https://bugs.llvm.org/show_bug.cgi?id=48922 For completeness: It turned out that it missed the LLVM 12 branch point - such that is is only in LLVM 13+ and not LLVM 12. (The LLVM 11 request was also ignored.) * * * Additionally, a very hard to hit corner case was missed that became easier to trigger due to an LLVM 13 change. - That one is still rare to hit (and does not prevent bootstrapping). It was fixed in LLVM 'main' and backported to LLVM releases/13.x (just after 13.0.1-RC1); thus, it will be in RC2 (if any) and 13.0.1. Cf. https://reviews.llvm.org/D114717 main: https://github.com/llvm/llvm-project/commit/c01c62c76c60a5a5da0496e41faae907944c92dd LLVM 13.x backport (for 13.0.1): https://github.com/llvm/llvm-project/issues/52607 https://github.com/llvm/llvm-project/commit/5932c004778cf251302db0d46d1dfb247325ed3f Thus: FIXED (only) in LLVM 13 - but best to use at least LLVM release/13.x or 13.0.1(-rc2). * * * GCC 12 also has several changes (mostly: configure checks to detect and act on the LLVM version) - to be able to use LLVM 13; several were backported to GCC 11 (releases/gcc-11). * * * Crossref: PR 100181 (-> PR 100181 comment 10) is another GCN-related issue, which was solved in LLVM 13
