 	generated by igen.
	(address_word): New.  Used by igen.

	* lf.c (lf_print_function_type_function): New, pass a function to
 	print out the type instead of a constant string.

	* igen.h, igen.c (print_semantic_function_formal,
 	SEMANTIC_FUNCTION_FORMAL): Relace macro with function.
	(print_semantic_function_actual, SEMANTIC_FUNCTION_ACTUAL): Ditto.
	(print_semantic_function_type, SEMANTIC_FUNCTION_TYPE): Ditto.
	(print_icache_function_type, ICACHE_FUNCTION_TYPE): Ditto.

	* gen-idecode.c (print_idecode_table): Update.
	(idecode_switch_leaf): Update.
	(print_idecode_switch_function_header): Ditto.
	(print_idecode_floating_point_unavailable): Ditto.
	(print_idecode_issue_function_header): Ditto.
	* igen.c (gen_icache_h): Ditto.
	* gen-engine.c (print_engine_table): Ditto.
	(engine_switch_leaf): Ditto.
	* gen-support.c (print_support_function_name): Ditto.

	(print_icache_internal_function_definition): Update.

	* gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
 	files, will at some stage need to move it into support.

	* igen.h, igen.c (main): New option -e <engine> - generate a full
 	simulation engine.  Previously this was the -d <idecode-file>
 	option.
	* gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
 	to clean these up so that that call upon the updated gen-idecode
	code.

	* gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
 	generating a decode table.

	* Makefile.in (igen): Add dependencies for new gen-engine.* files.

	* igen.h, igen.c (main): New option -M - Control what is returned
 	by semantic functions - -1/NIA vs CIA+N/NIA.  Add
 	generate_semantic_returning_modified_nia_only to igen_code enum.
	* gen-semantics.c (print_semantic_body): As an alternative, make
 	NIA == -1 instead of CIA+insn_size by default.

	* igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
 	New option -P <prefix> - Prepend all generated functions with the
 	specified prefix.

	* igen.c (main): Correct usage. Missleading message about ucase
 	options dumping internal tables.  -F now includes rather then
 	excludes instructions.

	* misc.h, misc.c (a2i): Make 64bit.

	* ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
 	max to 64bits, expect trouble.  Make the default 32 bits.
	* gen-idecode.c (print_idecode_table): Change EXTRACTED*
 	et.al. macro's to use the insn_bit_size instead of assuming 32
 	bits.
	* gen-icache.c (print_icache_extraction): Ditto.
	* gen-idecode.c (idecode_switch_start): Ditto.
	* gen-idecode.c (gen_idecode_c): Ditto

	* igen.h (insn_specifying_widths), igen.c (main): New option -W.
  	Indicates that the instruction field of the table is specifying
 	bit widths instead of bit offsets.
	* ld-insn.c (parse_insn_format): Parse instruction fields
 	specifying widths.

	* misc.c (a2i): Allow binary numbers to be specified using the
 	syntax 0bNNNN.
	* ld-insn.c: Allow such numbers to appear in the instruction
 	format.

	* table.c (table_entry_read): Make // a valid comment character.
	(table_entry_read): Skip lines containing a leading " - these may
 	eventually be used in a disasembler.
