From 663a1470e1a7af58a3d0691f480bc5621bd0c54f Mon Sep 17 00:00:00 2001
From: Alan Modra <amodra@gmail.com>
Date: Wed, 23 Mar 2011 15:25:06 +0000
Subject: bfd/ 	* elf32-ppc.c (ppc_elf_tls_optimize): Catch more cases where 
 old-style __tls_get_addr calls without marker relocs don't match 	their
 arg setup insn one for one.  If such mismatches are found 	report the
 reloc and don't do any tls optimization. 	* elf64-ppc.c
 (ppc64_elf_tls_optimize): Likewise. ld/testsuite/ 	*
 ld-powerpc/tlsmark.s: Delete non-optimizable section. 	*
 ld-powerpc/tlsmark32.s: Likewise. 	* ld-powerpc/tlsmark.d: Adjust to
 suit. 	* ld-powerpc/tlsmark32.d: Likewise. 	* ld-powerpc/tlsopt1.d, *
 ld-powerpc/tlsopt1.s: New. 	* ld-powerpc/tlsopt2.d, *
