           Summary: __FP_FAST_FMA not defined with -E
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: r...@gcc.gnu.org


The test

  optab_handler (fma_optab, mode) != CODE_FOR_nothing

always fails with -E because we never proceed that far.  See

do_compile:
      /* Language-dependent initialization.  Returns true on success.  */
      if (lang_dependent_init (main_input_filename))
        compile_file ();

c_common_init:
  if (flag_preprocess_only)
    {
      finish_options ();
      preprocess_file (parse_in);
      return false;
    }
