Unrolled build for rust-lang#122200

rust-timer · web-flow · commit ce8eb786a0e2 · 2024-04-10T00:48:12.000-04:00
Rollup merge of rust-lang#122200 - jieyouxu:unconditional-nightly-update-hint, r=estebank Unconditionally show update nightly hint on ICE Instead of trying to guess if a update nightly hint should be shown (by checking for system time, querying version and channel info etc.), just show the update nightly hint for nightly compilers. This avoids breaking tests that match on ICE test outputs on nightly/dev channels. > Another issue is that the outdated nightly hint triggers for ICE tests, causing a mismatch with the test expectation. There doesn't seem to be any env var to suppress this. See <https://rust-lang.zulipchat.com/#narrow/stream/326414-t-infra.2Fbootstrap/topic/stage0.20compiletest.20broken/near/425543681> for context.
