sunfish added a comment. (Emscripten does set the thread model.)
Whether WebAssembly should provide 64-bit atomics when on hardware where they're not lock-free is an interesting wasm design question, and the code here and in target-independent parts of clang may need to be changed as a result (right now, clang's target-independent code automatically defines __GCC_ATOMIC_LLONG_LOCK_FREE to 2 with this patch, which is incorrect). So that's a separate topic. I'd like to keep changes meant to fix the -mthread-model single case. https://reviews.llvm.org/D28381 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
