           Summary: gcc seems to generate wrong-code for some inline-
                    assembly
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P1
         Component: inline-asm
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: rehsack at liwing dot de
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: FreeBSD 5.1-CURRENT i386
  GCC host triplet: FreeBSD 5.1-CURRENT i386
GCC target triplet: FreeBSD 5.1-CURRENT i386

When building the freebsd 5.1-current kernel with the newly introduced
gcc-3.3.1, the assembler gets "invalid character '_' in mnemonic" in some places.
