             Bug #: 55194
           Summary: h8300 ICE during conftest in libgcc dwarf2out:7605
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: joel@gcc.gnu.org


When building newlib using the gcc-svn head, the compiler generates assembly
language that cannot be assembled by the binutils cvs head or 2.22

xgcc (GCC) 4.8.0 20121103 (experimental) [trunk revision 193124]

This is enough to trip the bug:

/home/joel/v850/tools/b-gcc-svn/./gcc/xgcc
-B/home/joel/v850/tools/b-gcc-svn/./gcc/ -c -O2 -g h8300_bug.c 

Dropping the -g is sufficient to let it compile.

Test case is very basic:

int main(int argc, char **argv)
{
  return 0;
}

The full command line:

configure:3374:  /home/joel/v850/tools/b-gcc-svn/./gcc/xgcc
-B/home/joel/v850/tools/b-gcc-svn/./gcc/ -nostdinc
