Something seems to be going wrong with the CI on the wasm32-wasi target 🤔 I tried bisecting using the CI, but it seems to fail all the time regardless of the commits I include, and the failure seems strange does that sound familiar to anyone ? |

This is probably because of the upgrade to LLVM 12 (rust-lang/rust#81451). Just disable wasm CI for now and create an issue. |
The LLVM12 upgrade in rustc may be causing issues

CI passes so I created #1048 to track re-enabling the WASM builder after this PR lands |

Not a big deal unless one of those intrinsics calls the others: we can't easily cast between the 2 types, even (to the extent of my abilities) via the associated const trick to cast.
min_const_genericsrefuses to compile such a naive trick constant in this position (and we cannot naively use either these immediates in the const expressions casts with{}). (There are around 10 cases like this in this file).x86/rtm.rs: (which I believe completes this file)
_xabort(it may be wishful thinking on my part, but while working on these conversions the past few days, it felt like incremental check builds are slowly but surely getting faster)
