           Summary: -fno-unit-at-a-time should disable all ipo
           Product: tools
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: llvm-gcc
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org


GCC's -fno-unit-at-a-time, basically now means 'disable all ipo except inlining'.  This understanding is 
expected by crtstuff.c in the GCC build.  We could remove some llvm-local hacks from crtstuff if we made 
-fno-unit-at-a-time disable IPO (specific dead global var deletion).
