           Summary: c-family/c-cppbuiltin.c: duplicate if expressions
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: dcb314@hotmail.com


I just ran the static analysis tool cppcheck-1.49 over the source code
of snapshot 20110611 on a Fedora Linux x86_64 box.

The tool said

[gcc/c-family/c-cppbuiltin.c:562] -> [gcc/c-family/c-cppbuiltin.c:557]: (style)
Found duplicate if expressions.

The source code is

  if (!prev->x_flag_finite_math_only && cur->x_flag_finite_math_only)
    {
      cpp_undef (pfile, "__FINITE_MATH_ONLY__");
      cpp_define (pfile, "__FINITE_MATH_ONLY__=1");
    }
  else if (!prev->x_flag_finite_math_only && cur->x_flag_finite_math_only)

I agree with the tool. This looks like a possible cut'n'paste error.
Suggest code rework.
