           Summary: llvm+checking never finishes compiling
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Common Code Generator Code
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: astrange at ithinksw.com
                CC: llvmbugs at cs.uiuc.edu


Created an attachment (id=5448)
 --> (http://llvm.org/bugs/attachment.cgi?id=5448)
preprocessed source

Attached file didn't stop compiling after 20 minutes with x86-64-apple-darwin10
+ llvm/clang trunk with checking enabled and:
> /usr/local/llvm/bin/clang -O3 -Xclang -ftime-report -c fft.i

Seems to be caused by the inliner causing the size of fft65536() to explode.
