2a55acbc1de0b8d1901988ee4f17d5697519c2d2 is the first bad commit commit 2a55acbc1de0b8d1901988ee4f17d5697519c2d2 Author: Dave Airlie <airlied@redhat.com> Date: Tue Jul 2 07:10:53 2019 +1000 gallivm: add compare exchange wrapper This just pulls the wrapper from LLVM for older versions Reviewed-by: Roland Scheidegger <sroland@vmware.com> :040000 040000 cee7aedaa0ddff70fc6ab1b45205ed5d9d7bf771 4aa821efcbb5ee85301518e72b79afb636a1fd0f M src bisect run success Seems like different llvm versions (before 5.0) need different wrappers for AtomicCmpXchg(). Pretty much the same issue as bug 111102. Although I can't reproduce this bug actually, maybe depends on compiler. (I can reproduce the other one, for llvm 3.5-3.8 the function parameters are wrong.) Though I'm wondering if we actually need a mapping function, isn't it possible to just static cast the c enum to the class enum (as in (llvm::AtomicOrdering)SuccessOrdering)? Any idea why the GitLab CI pipeline scons-llvm job doesn't hit this, which builds against LLVM 3.4.2? (See e.g. https://gitlab.freedesktop.org/mesa/mesa/-/jobs/460746) It could be due to different default C++ standards used in different compilers. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
