Thanks, Alex! I suspected that might be the case. Follow-up question: What kind of binary compatibility guarantees does Rust have when mixing compiler versions? Would it be a problem for example if we rewrote the TLS mechanism from scratch so that it worked differently in LLVM 12 than it does in LLVM 11?

Sam, I don't think we can land this change because it would prevent Rust from working with tip-of-tree LLVM.
