I've retriggered CI, just in case it was some weird ephemeral issue (haven't really had those issues as far as I can remember)
@jhpratt no updates; you may be interested in reading the discussion in https://github.com/rustwasm/team/issues/162 however.
@dtolnay can you describe what maintainership of syntex/aster/quasi looks like in practice? Is it mostly un-nightly-ifying code from rustc? bindgen would be pretty negatively impacted by the loss of syntex.
> it also mean giving up ~10-20% execution performance when using explicit checks. FWIW, the overheads can be much greater than that, depending on the benchmark. I've [measured](https://github.com/bytecodealliance/wasmtime/issues/6094) ~1.55x slow...
I'd love to get to this one day. My Wasm GC work is producing two patterns that require implementing the optimization of trapping arithmetic to get good code: * `(uadd_overflow_trap...
This was fixed in https://github.com/bytecodealliance/wasmtime/pull/10524
Some initial, limited optimization of instructions without results was enabled in https://github.com/bytecodealliance/wasmtime/pull/10524
While we gained some initial support for optimizing side-effectful instructions in https://github.com/bytecodealliance/wasmtime/pull/10524, that PR specifically disallows anything that changes the CFG because of the complication mentioned in this OP: >...
