Test differences

Show 28 test diffs

Stage 1

• [codegen] tests/codegen-llvm/issues/signed-nonzero-matches.rs: [missing] -> pass (J1)

Stage 2

• [codegen] tests/codegen-llvm/issues/signed-nonzero-matches.rs: [missing] -> pass (J0)

Additionally, 26 doctest diffs were found. These are ignored, as they are noisy.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
