* 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, * ld-powerpc/tlsopt2.s: New. * ld-powerpc/tlsopt3.d, * ld-powerpc/tlsopt3.s: New. * ld-powerpc/tlsopt4.d, * ld-powerpc/tlsopt4.s: New. * ld-powerpc/tlsopt1_32.d, * ld-powerpc/tlsopt1_32.s: New. * ld-powerpc/tlsopt2_32.d, * ld-powerpc/tlsopt2_32.s: New. * ld-powerpc/tlsopt3_32.d, * ld-powerpc/tlsopt3_32.s: New. * ld-powerpc/tlsopt4_32.d, * ld-powerpc/tlsopt4_32.s: New. * ld-powerpc/powerpc.exp: Run new tests.
