commit 7af8396e63463638dfba5ab732b2380cffd0774c
Author: Maciej W. Rozycki <macro@codesourcery.com>
Date:   Fri Dec 6 23:20:14 2013 +0000

    MIPS: MIPS16 and microMIPS PLT entry support for binutils 2.24
    
    This is a backport from trunk to handle MIPS16 and microMIPS code in
    PLT entries as produced by LD from binutils version 2.24 onwards.  This
    feature requires explicit support in GDB for correct operation when
    debugging through function calls made via the PLT.
    
    	bfd/
    	* elfxx-mips.h (_bfd_mips_elf_get_synthetic_symtab): New
    	prototype.
    	* elf32-mips.c (elf_backend_plt_sym_val): Remove macro.
    	(bfd_elf32_get_synthetic_symtab): New macro.
    	* elfxx-mips.c (micromips_o32_exec_plt0_entry): New variable.
    	(micromips_insn32_o32_exec_plt0_entry): Likewise.
    	(mips16_o32_exec_plt_entry): Likewise.
    	(micromips_o32_exec_plt_entry): Likewise.
    	(micromips_insn32_o32_exec_plt_entry): Likewise.
    	(_bfd_mips_elf_get_synthetic_symtab): New
    	function.
    
    	gdb/
    	* mips-tdep.c (mips_elf_make_msymbol_special): Handle MIPS16 and
    	microMIPS synthetic symbols.
    
    	opcodes/
    	* mips-dis.c (is_mips16_plt_tail): New function.
    	(print_insn_mips16): Handle MIPS16 PLT entry's GOT slot address
    	word.
    	(is_compressed_mode_p): Handle MIPS16/microMIPS PLT entries.
