I would suspect it is related to rust-lang/stdarch#1693.
I wonder if the definition of vqsub_u8 changed?

[ehuss]

That particular test (test_vqsub_u8) passes with the LLVM backend, but not cranelift.

@bjorn3 Do you have any ideas?

💔 Test failed - checks-actions

[workingjubilee]

bjorn3 thinks it was this miscompilation: rust-lang/rustc_codegen_cranelift#1560

bjorn3 thinks it was this miscompilation: rust-lang/rustc_codegen_cranelift#1560

From what I can tell, with the latest cranelift (or #137078), the test still fails.
