	* elf32-spu.h (struct spu_elf_params): ovly_flavour now only 1 bit.
	Add compact_stub.
	(emum _ovly_flavour): Delete ovly_compact, ovly_none.
	* elf32-spu.c (struct spu_link_hash_table): Replace ovly_load and
	ovly_return fields with ovly_entry[2].  Adjust all users.
	(spu_elf_find_overlays): Set ovly_entry[1] from __icache_call_handler
	when soft-icache.
	(spu_elf_build_stubs): Likewise.
	(ovl_stub_size): Change arg to spu_elf_params pointer.  Adjust for
	ovly_flavour changes.  Update all callers.
	(ovl_stub_size_log2): New function.
	(build_stub): Handle compact icache stubs.  Use different manager
	entry point for stubs in non-icache area.
	(spu_elf_size_stubs): Don't allocate space for indirect branch
	descriptors.
	(spu_elf_build_stubs): And don't built them.
ld/
	* emultempl/spu_icache.S: Add new entry to dummy handler.
	* emultempl/spu_icache.o_c: Regenerate.
	* emultempl/spuelf.em (params): Init new field.
	(no_overlays): New static var.
	(spu_before_allocation): Use it.
	(OPTION_SPU_COMPACT_STUBS): Define.
	(PARSE_AND_LIST_LONGOPTS, PARSE_AND_LIST_OPTIONS): Add compact-stubs.
	(PARSE_AND_LIST_ARGS_CASES): Handle compact-stubs.  Adjust no-overlays
	handling.
ld/testsuite/
	* ld-spu/icache1.d: Update for fixed set_id, new manager entry, and
	reduced data.
