What happens if this gets merged without that PR? By default, all tracing is still disabled in Miri, right? |
Yes, this can be merged without issues even before rust-lang/miri#4406 |
Okay, then please make the PR & description ready for that. :) |

Rollup merge of #143051 - Stypox:tracing-validity, r=RalfJung Add tracing to `validate_operand` This PR adds a tracing call to keep track of how much time is spent in `validate_operand` and `const_validate_operand`. Let me know if more fine-grained tracing is needed (e.g. adding tracing to `validate_operand_internal` too, which is just called from those two functions). I also fixed the rustdoc of `validate_operand` and `const_validate_operand` since it was referencing an older name for the `val` parameter which was renamed in cbdcbf0. Here is some tracing output when Miri is run on `src/tools/miri/tests/pass/hello.rs`, visualizable in [ui.perfetto.dev](https://ui.perfetto.dev/): [trace-1750932222218210.json](https://github.com/user-attachments/files/20924000/trace-1750932222218210.json) **Note: obtaining tracing output depends on rust-lang/miri#4406, but this PR is standalone and can be merged without waiting for rust-lang/miri#4406 r? `@RalfJung`
