             Bug #: 14540
           Summary: GDB for ARM target fails to build with clang
           Product: gdb
           Version: 7.5
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: eblotml@free.fr
    Classification: Unclassified


clang compiler throws the following error:

armsupp.c:639:7: error: non-void function 'ARMul_MRC' should return a value
[-Wreturn-type]
      return;

for arm-eabi generic target.

host is OS X 10.8.1

It seems the function:


ARMword
ARMul_MRC (ARMul_State * state, ARMword instr)
{
  unsigned cpab;
  ARMword result = 0;

  if (! CP_ACCESS_ALLOWED (state, CPNum))
    {
      ARMul_UndefInstr (state, instr);
      return;
    }

   ...
}

is actually missing an error value.
