Hello!

2013-08-26  Uros Bizjak  <ubizjak@gmail.com>

    * config/i386/i386.c (ix86_debug_options): Remove prototype.
    (x86_64_elf_select_section): Ditto.
    (ix86_handle_tm_regparm_attribute): Remove ATTRIBUTE_UNUSED on used
    arguments.
    (ix86_pass_by_reference): Ditto.
    (ix86_return_in_memory): Ditto.
    (output_set_got): Ditto.
    (ix86_unary_operator_ok): Ditto.
    (ix86_expand_builtin): Ditto.

Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN.

Uros.

This doesn't look right, because the SUBTARGET_RETURN_IN_MEMORY
definitions (interix and i386elf) don't mention the FNTYPE anywhere.

Uh, I missed the "#else".

Fixed in a followup patch.

Thanks,
