PowerPC dynamic relocations

[deliverable/binutils-gdb.git] / bfd / ChangeLog

2017-01-24  Alan Modra  <amodra@gmail.com>

	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Merge two cases
	where dynamic relocs are preferable.  Allow ifunc too.
	(ensure_undefweak_dynamic): New function.
	(allocate_dynrelocs): Use it here.  Move plt handling last and
	don't make symbols dynamic, simplifying loop.  Only make undef
	weak symbols with GOT entries dynamic.  Correct condition
	for GOT relocs.  Handle dynamic relocs on ifuncs.  Correct
	comments.  Remove goto.
	(ppc_elf_relocate_section): Correct test for using dynamic
	symbol on GOT relocs.  Rearrange test for emitting GOT relocs
	to suit.  Set up explicit tls_index entries and implicit GOT
	tls_index entries resolvable at link time for
	__tls_get_addr_opt.  Simplify test to clear mem for prelink.
	* elf64-ppc.c (allocate_got): Correct condition for GOT relocs.
	(ensure_undefweak_dynamic): New function.
	(allocate_dynrelocs): Use it here.  Only make undef weak symbols
	with GOT entries dynamic.  Remove unnecessary test of
	WILL_CALL_FINISH_DYNAMIC_SYMBOL in PLT handling.
	(ppc64_elf_relocate_section): Correct test for using dynamic
	symbol on GOT relocs.  Rearrange test for emitting GOT relocs
	to suit.  Set up explicit tls_index entries and implicit GOT
	tls_index entries resolvable at link time for __tls_get_addr_opt.
	Simplify expression to clear mem for prelink.
