Re: [PATCH 1/5] Add recog_constrain_insn

This patch just adds a new utility function called recog_constrain_insn,
to go alongside the existing recog_constrain_insn_cached.

Note that the extract_insn in lra.c wasn't used when checking is disabled.
The function just moved on to the next instruction straight away.


	* recog.h (extract_constrain_insn): Declare.
	* recog.c (extract_constrain_insn): New function.
	* lra.c (check_rtl): Use it.
	* postreload.c (reload_cse_simplify_operands): Likewise.
	* reg-stack.c (check_asm_stack_operands): Likewise.
	(subst_asm_stack_regs): Likewise.
	* regcprop.c (copyprop_hardreg_forward_1): Likewise.
	* regrename.c (build_def_use): Likewise.
	* sel-sched.c (get_reg_class): Likewise.
	* config/arm/arm.c (note_invalid_constants): Likewise.
	* config/s390/ (execute_operation): Likewise.
OK. I'm going to assume passing "reload_completed" is equivalent to the prior code where we passed the constant "1" to constrain_operands.
