commit cb22ccf4110d82441b8d56875419d871f10f3f8f
Author: Kwok Cheung Yeung <kcy@codesourcery.com>
Date:   Thu Apr 17 14:13:44 2014 +0100

    This patch causes local GOT entries addressed via a 16-bit index to
    be placed towards the front of local GOT space, while entries addressed
    via a 32-bit index are placed towards the rear.
    
    Provided that there are fewer than ~16K local GOT entries addressed via
    a 16-bit index in total, this should eliminate any relocation overflows
    caused by such GOT entries being allocated beyond the addressable range.
    
    bfd/
    	* elfxx-mips.c (struct mips_got_info): Delete assigned_gotno
    	field.  Add assigned_low_gotno and assigned_high_gotno fields.
    	(mips_elf_create_local_got_entry): Update out-of-space condition.
    	Set index of new GOT entry to assigned_low_gotno if required by
    	the current relocation, else set it to assigned_high_gotno.
    	(mips_elf_set_global_gotidx): Replace uses of assigned_gotno
    	with assigned_low_gotno.
    	(mips_elf_multi_got): Initialize assigned_low_gotno and
    	assigned_high_gotno in secondary GOTs.  Use assigned_low_gotno
    	in place of assigned_gotno when handling global GOT entries.
    	(mips_elf_lay_out_got): Initialize assigned_low_gotno and
    	assigned_high_gotno.
    	(_bfd_mips_elf_finish_dynamic_sections): Account for a possible
    	gap in the middle of local GOT space.

    	* ld-mips-elf/elf-rel-xgot-n32.d: Update for new GOT layout.
