The tools/llvm-dwarfdump/X86/{prettyprint_types,simplified-template-names}.s tests seem to fail on 32-bit Arm (bus error) (tested at commit 0be1fbac2a7797399c0970e3f4033288036b65f6).

Are they expected to work on 32-bit ARM? The tests are inside an x86 folder...

thesamesam commented 1 year ago

No idea, but they should be skipped if not 😉

In general, the "cross-arch" tests seem to work well in LLVM, but this might be different because it's in tools/.
