Re: Calls to qp float lib out of sparcv9 head compiler


Hello again,

 sparc_override_options currently reads :

  /* We force all 64bit archs to use 128 bit long double */
  if (TARGET_64BIT && ! TARGET_LONG_DOUBLE_128)
    {
      error ("-mlong-double-64 not allowed with -m64");
      target_flags |= MASK_LONG_DOUBLE_128;
    }

 As the sparc64 support has evolved a lot recently, are there known reasons
 for this to still be enforced ?

 Thanks in advance,

 Olivier
