Re: [PATCH] re-enable -mabi=no-altivec, use -mabi=altivec as default for powerpc-linux

How about the following?

  /* The AltiVec ABI is the default for PowerPC-64 GNU/Linux.  For
     PowerPC-32 GNU/Linux, -maltivec implies the AltiVec ABI.  It can
     be explicitly overridden in either case.  */
  if (TARGET_ELF)
    {
      if (!rs6000_explicit_options.altivec_abi
          && (TARGET_64BIT || TARGET_ALTIVEC))
        rs6000_altivec_abi = 1;

      /* Enable VRSAVE for AltiVec ABI, unless explicitly overridden.  */
      if (!rs6000_explicit_options.vrsave)
        TARGET_ALTIVEC_VRSAVE = rs6000_altivec_abi;
    }

Thanks, David
