+ * elf32-ppc.c (ppc_elf_relocate_section): Remove unnecessary test.
+ * elf64-ppc.c (ppc64_elf_tls_optimize): Decrement tlsld_got.refcount
+ on invalid LD relocs.
+ (allocate_dynrelocs): Invalid LD relocs don't use tlsld_got entry.
+ (ppc64_elf_relocate_section): Unify new handling of LD relocs and
+ tlsld_got entry. Use IS_PPC64_TLS_RELOC.
+
* elf32-ppc.h: New file.
* elf32-ppc.c: Include elf32-ppc.h.
(NOP, CROR_151515, CROR_313131, TP_OFFSET, DTP_OFFSET): Define.
