Weird, so as far as I understand, we use beta to build stage 1 and then use stage 1 to build stage 2 and then use stage 2 or 1 to build ra (in bootstrap) which ICEs, but i was not able to reproduce this by compiling hir-ty inside the ra git repo directly with nightly/master :/

Maybe the fail will manifest tomorrow ?

Hmm I am able to reproduce this in the rust-analyzer repo with -Zmir-opt-level=5 or 4, I thought that "3" was the default when doing a --release build but perhaps I'm wrong there...

I tried to minimize with cargo-minimize but it threw an error while doing so :/

a panic? if so you can probably fix it by staring very closely at the cursed "path" code from cargo-minimize and figuring out which AST nodes aren't yet counted and leads to duplicate paths.

No panic (/stacktrace) by c-minimize, just an error.
I tried to cargo build the remaining code but there were errors, maybe it failed to apply a rustc suggestion

Unrolled build for rust-lang#119077

Rollup merge of rust-lang#119077 - tmiasko:lint, r=cjgillot

Separate MIR lints from validation

Add a MIR lint pass, enabled with -Zlint-mir, which identifies undefined or
likely erroneous behaviour.

The initial implementation mostly migrates existing checks of this nature from
MIR validator, where they did not belong (those checks have false positives and
there is nothing inherently invalid about MIR with undefined behaviour).
