stdarch is developed in its own repository. If possible, consider making this change to rust-lang/stdarch instead.

Can you add a

//@ normalize-stderr:

line at the top of the relevant test which fixes up the "and XX more" from a number like 75 or whatever that constantly gets diffed into a normalized value? It should leave the rest of the test output unchanged, in particular it has to suggest the same features first.

[folkertdev]

Could you make the changes in library/stdarch/crates/core_arch/* as a separate PR over at rust-lang/stdarch? As written this PR will break stdarch CI. We'll sync changes back over to here once merged over there.

That's already mailed as #158922 - probably that will land faster than this.

Prepped rust-lang/stdarch#2184.
