* igen.c (main): Change -I to add include paths for :include: files. Implement -G as per sim/igen, with just gen-icache=N support. Call load_insn_table() with the built include path. * ld-insn.c (parse_include_entry): New. Load an :include: file. (load_insn_table): New `includes' argument. Look for :include: entries and call parse_include_entry() for them. (main): Adjust load_insn_table() call. * ld-insn.h (model_include_fields): New enum. (load_insn_table): Update prototype. * table.c (struct _open_table, struct _table): Rework structures to handle included files. (table_push): Move the guts of table_open() here. * table.c (struct _open table, struct table): Make table object an indirect ptr to the current table file. (current_line, new_table_entry, next_line): Make file arg type open_table. (table_open): Use table_push. (table_entry_read): Point variable file at current table, at eof, pop last open table. * misc.h (NZALLOC): New macro. From sim/igen. * table.h, table.c (table_push): New function.
