             Bug #: 53201
           Summary: [4.8 Regression] unrecognized command line option
                    '-mno-lzcnt-mno-hle
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: burnus@gcc.gnu.org
                CC: kyukhin@gcc.gnu.org


The patch at http://gcc.gnu.org/ml/gcc-cvs/2012-05/msg00047.html seemingly
misses a " ".

Compiling a file with -march=native fails here with:

  unrecognized command line option '-mno-lzcnt-mno-hle


Untested patch. (Note: An all language bootstrapping takes too long on my
machine - thus, I'd prefer if someone else handles this. Thanks to Joseph for
the pointer.)
