	(spu_elf_setup): Init line_size_log2 and num_lines_log2.
	(spu_elf_find_overlays): For soft-icache, mark any section within cache
	area as an overlay, and check that no other overlays exist.  Look up
	icache overlay manager entry sym.
	(BRA_STUBS, BRA, BRASL): Define.
	(enum _stub_type): Replace ovl_stub with call_ovl_stub and br*_ovl_stub.
	(needs_ovl_stub): Adjust for soft-icache.  Return priority encoded
	in branch insn.

	(spu_elf_stack_analysis): Only print when htab->stack_analysis.
	(spu_elf_final_link): Call spu_elf_stack_analysis for lrlive
	analysis.  Call spu_elf_build_stubs.

	into addresses.
	(spu_elf_output_symbol_hook): Support soft-icache.
	(spu_elf_modify_program_headers: Likewise.
	* elf32-spu.h (struct spu_elf_params): Add lrlive_analysis.  Rename

	* config/tc-spu.c (md_pseudo_table): Add "brinfo".
	(brinfo): New var.
	(md_assemble): Poke brinfo into branch instructions.
	(spu_brinfo): New function.
