(decl_attributes): Handle A_NO_LIMIT_STACK. * c-decl.c (duplicate_decls): Handle DECL_NO_LIMIT_STACK. * explow.c (allocate_dynamic_stack_space) [!HAVE_allocate_stack]: Handle stack bounds checking. * flags.h (flag_stack_check): Use the word 'probe' rather than 'check', because the flag doesn't actually cause any checking to be done. * function.c (expand_function_start): Set current_function_limit_stack. * function.h (struct function): Add limit_stack. (current_function_limit_stack): Define. * invoke.texi (Code Gen Options): Document new options. * rtl.h: Declare stack_limit_rtx. * toplev.c (stack_limit_rtx): New variable. (decode_f_option): Handle new options -fstack-limit-register=REG, -fstack-limit-symbol=IDENT, -fno-stack-limit. (main): Add stack_limit_rtx as GC root. * tree.h (DECL_NO_LIMIT_STACK): New macro.

(conditional_trap): New insn. * md.texi (Standard Names): Document `trap' and `conditional_trap'. * optabs.c (gen_cond_trap): Use start_sequence()/end_sequence() so a cc0 setter doesn't get emitted at some random place in the function. * config/i960/i960.md (trap): New insn. (conditional_trap): New expander. (conditional_trap+1, conditional_trap+2): New insns for signed and unsigned cases. * config/i960/i960.c (i960_function_prologue): Use STARTING_FRAME_OFFSET.
