* Makefile.in (stupid.o): Update dependencies. (global.o): Likewise. * global.c: Include reload.h (reg_becomes_live): New function. (reg_dies): New function. (build_insn_chain): New function. (global_alloc): Call build_insn_chain before calling reload. * reload.h (struct needs): New structure definition. (struct insn_chain): Likewise. (reload_insn_chain): Declare variable. (new_insn_chain): Declare function. * reload1.c (reload_startobj): New variable. (reload_insn_chain): New variable. (unused_insn_chains): New variable. (new_insn_chain): New function. (init_reload): Initialize reload_startobj, not reload_firstobj. (reload): Initialize reload_firstobj. Before returning, free everything on the reload_obstack. * stupid.c: Include insn-config.h, reload.h and basic-block.h. (reg_where_dead_chain, reg_where_born_exact, reg_where_born_clobber, current_chain): New variables. (reg_where_born): Delete variable. (REG_WHERE_BORN): New macro. (find_clobbered_regs): New function. (stupid_life_analysis): Don't allocate/free reg_where_born. Allocate and free reg_where_born_exact, reg_where_born_clobber, reg_where_dead_chain. Use REG_WHERE_BORN instead of reg_where_born. While processing the insns, build the reload_insn_chain with information about register lifetimes. (stupid_reg_compare): Use REG_WHERE_BORN instead of reg_where_born. (stupid_mark_refs): Replace arg INSN with arg CHAIN. All callers changed. Compute and information about birth and death of pseudo registers in reg_where_dead_chain, reg_where_born_exact and reg_where_born_clobber. Delete code to set elements of reg_where_born.
