bfd/
	* bfd-in.h (bfd_xcoff_size_dynamic_sections): Replace the
	bfd_boolean export_defineds parameter with an unsigned int
	auto_export_flags parameter.
	* bfd-in2.h: Regenerate.
	* xcofflink.c (xcoff_archive_contains_shared_object_p): New function,
	split out from xcoff_build_ldsyms.
	(xcoff_covered_by_expall_p): New function.
	(xcoff_auto_export_p): New function, split out from xcoff_build_ldsyms
	but with extra code to handle -bexpfull and -bexpall.
	(xcoff_mark_auto_exports): New function.
	(xcoff_build_ldsyms): Use xcoff_auto_export_p to decide whether
	a function should be automatically exported.
	(bfd_xcoff_size_dynamic_sections): Replace the export_defineds
	parameter with an auto_export_flags parameter.  Update ldinfo
	accordingly.  Use xcoff_mark_auto_exports to mark all automatically-
	exported symbols.

ld/
	* emultempl/aix.em (auto_export_flags): New variable.
	(explicit_auto_export_flags): Likewise.
	(OPTION_EXPALL, OPTION_EXPFULL): New enum values.
	(OPTION_NOEXPALL, OPTION_NOEXPFULL): Likewise.
	(gld${EMULATION_NAME}_add_options): Add -bexpall, -bexpfull,
	-bnoexpall and -bnoexpfull.
	(gld${EMULATION_NAME}_handle_option): Handle them.
	(gld${EMULATION_NAME}_before_allocation): Update the call to
	bfd_size_dynamic_sections.

ld/testsuite/
