2023-12-13Rollup merge of #118871 - tmiasko:coroutine-maybe-uninit-fields, ↵Matthias Krüger-0/+37
r=compiler-errors Coroutine variant fields can be uninitialized Wrap coroutine variant fields in MaybeUninit to indicate that they might be uninitialized. Otherwise an uninhabited field will make the entire variant uninhabited and introduce undefined behaviour. The analogous issue in the prefix of coroutine layout was addressed by 6fae7f807146e400fa2bbd1c44768d9bcaa57c4c.

2023-11-28Fix coroutine validation for mixed panic strategyTomasz Miąsko-0/+24
Validation introduced in #113124 allows UnwindAction::Continue and TerminatorKind::Resume to occur only in functions with ABI that can unwind. The function ABI depends on the panic strategy, which can vary across crates. Usually MIR is built and validated in the same crate. The coroutine drop glue thus far was an exception. As a result validation could fail when mixing different panic strategies. Avoid the problem by executing AbortUnwindingCalls along with the validation.

2023-11-17Rollup merge of #117338 - workingjubilee:asmjs-meets-thanatos, r=b-naberMatthias Krüger-2/+0
Remove asmjs Fulfills [MCP 668](https://github.com/rust-lang/compiler-team/issues/668). `asmjs-unknown-emscripten` does not work as-specified, and lacks essential upstream support for generating asm.js, so it should not exist at all.
