           Summary: diagnostics in LLParser
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: LLVM assembly language parser
        AssignedTo: unassignedbugs at nondot.org

I ran a bunch of polygen-generated testcases through
the new AsmParser implementation. Attached are some
testcases that either trigger assertion failures
due to llvm-as not diagnosing invalid constructs,
some that are rejected by the old AsmParser and
accepted by the new AsmParser and look questionable,
and some that are rejected by the new AsmParser that
look questionable.

FWIW, the new AsmParser also correctly diagnoses many
errors that the old one missed :-).
