cfallin opened PR #1741 from filetest-vcode-compile to master:

I hadn't realized before that the filetest backend for test vcode is
doing essentially what compile is doing, but for new (MachInst)
backends: it is just getting a disassembly and running it through
filecheck. There's no reason not to reuse test compile for the AArch64
tests as well.

This was motivated by the desire to have "this IR compiles successfully"
tests work on both x86 and AArch64. It seems this should work fine by
adding multiple target directives when a test case should be
compile-tested on multiple architectures.

Should this be guarded by if isa.get_mach_backend().is_some() ... like below then?

I hadn't noticed this mach_compile_result before and this comment is irrelevant to this PR, but it does feel like there is probably a re-factoring out there somewhere where the new backend and the old co-exist a little more cleanly (e.g. have the Mach logic in DisplayFunction and TargetIsa instead of a separate top-level field or something along those lines).

Yeah, in general I agree; it's a little tricky because the interfaces don't provide quite the same functionality, but I'll think about this a bit more to see if there isn't some way to clean it up.
