           Summary: LLVM needs a tool for pattern match LLVM IR
           Product: Test Suite
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DejaGNU
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: daniel at zuster.org

Trying to match patterns in LLVM IR using grep is painful and error prone,
especially when trying to look for a pattern that spans multiple instructions.

We should implement some kind of basic tool for match parts of the LLVM IR
against a pattern for use in writing simple test cases.
