Unfortunately there are very few volunteers that triage the bug backlog and
posting new comments to old bugs does not send email to llvm-bugs at . This means
LLVM is often unintentionally deaf to old longstanding issues unless duplicates
are reported, which is more or less what you're doing and perfectly reasonable
given the existing limitations of our bug tracker and triage process.

Anyway, this should be fixed with r315953, and I'm going to mark it duplicated
for tracking purposes. Thanks for re-filing!

I agree, LLVM's assembler isn't very usable. It was built to eliminate LLVM's
dependency on external assemblers, and not to be used by humans. =(
