           Summary: bugpoint could trap function parameters
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: bugpoint
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nlewycky at google.com

When analyzing a miscompile, Bugpoint could try instrumenting the function to
keep track of the arguments received before running the rest of the function.
Alternately, it could do this at the call site.

It should then use that info to construct a simpler testcase than the usual
"bugpoint-tooptimize.bc" which is the entire other half of the program.
