           Summary: -O0 compile time: stop llvm-gcc from making llvm values
                    named "tmp"
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Keywords: slow-compile
          Severity: normal
          Priority: P2
         Component: llvm-gcc
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org
                CC: llvmbugs at cs.uiuc.edu


Duncan found that the symbol table traffic of pushing around local value named
'tmp' are a significant portion of -O0 compile times.  Disabling this sped
things up a lot.  We should consider doing this.
