[llvm-dev] DWARF debug info unit tests: Tests for wrong triple?

[Eric Christopher via llvm-dev]

Adding in aprantl here to make sure he's aware.

Making sure I understand - you're building a compiler on machine a
that llvm doesn't support code generation to and running the llvm
tests on that platform?

That's probably a bit out of what any of us expected here as the
typical one is to use build llvm on a platform that it already
supports. I do agree that default target would also work here as a
suitable test.
