LLVM 15 compatibility fixes These are LLVM 15 compatibility fixes split out from #99464. There are three changes here: * Emit elementtype attribtue for ldrex/strex intrinsics. This is requires as part of the opaque pointers migration. * Make more tests compatible with opaque pointers. These are either new or aren't run on x86. * Remove a test for `#[rustc_allocator]`. Since #99574 there are more requirement on the function signature. I dropped the test entirely, since we already test the effect of the attribute elsewhere. * The main change: When a worker thread emits an error, wait for other threads to finish before unwinding the main thread and exiting. Otherwise workers may end up using globals for which destructors have already been run. This was probably never quite correct, but became an active problem with LLVM 15, because it started using global dtors in critical places, as part of ManagedStatic removal. Fixes #99432 (and probably also #95679). r? `@cuviper` |
