Can we limit this just to rustc-rayon (via an override in Cargo.toml) or builders enabling the parallel compiler, without which rustc-rayon shouldn't be used iirc? |
|
I tried to somehow modify cargo flags of the rustc-rayon dependency via rustcs Cargo.toml but without success. :/ |
|
Putting this in the top-level Cargo.toml should work: [profile.release.package.rustc-rayon-core]
overflow-checks = falseWe already do this for compiler-builtins. Edited: Overflow is indeed in rustc-rayon-core. |
|
Don't we need it in rustc-rayon-core? Maybe I'm misremembering but I saw it mentioned somewhere |
|
@hkratz can you open a pr? I'd close this in favor of a cargo.toml fix then :) |
|
Great, thank you! :) |

This PR temporarily disables the overflow checks again so we don't have to deal with the "spurious" CI failures until rustc-rayon is fixed.
