final.c (cleanup_subreg_operands): Delete some unused code.
* final.c (cleanup_subreg_operands): Delete some unused code.
* recog.h (MAX_RECOG_ALTERNATIVES): New macro.
(struct insn_alternative): New structure definition.
(recog_op_alt): Declare variable.
(preprocess_constraints): Declare function.
* recog.c (recog_op_alt): New variable.
(extract_insn): Verify number of alternatives is in range.
(preprocess_constraints): New function.
* reg-stack.c: Include recog.h.
(constrain_asm_operands): Delete.
(get_asm_operand_lengths): Delete.
(get_asm_operand_n_inputs): New function.
(record_asm_reg_life): Delete OPERANDS, CONSTRAINTS, N_INPUTS and
N_OUTPUTS args. All callers changed.
Compute number of inputs and outputs here by calling
get_asm_operand_n_inputs.
Instead of constrain_asm_operands, call extract_insn,
constrain_operands and preprocess_constaints. Use information
computed by these functions throughout.
(record_reg_life): Delete code that is unused due to changes in
record_asm_reg_life.
(subst_asm_stack_regs): Delete OPERANDS, OPERAND_LOC, CONSTRAINTS,
N_INPUTS and N_OUTPUTS args. All callers changed.
Similar changes as in record_asm_reg_life.
(subst_stack_regs): Move n_operands declaration into the if statement
where it's used.
Delete code that is unused due to changes in subst_asm_stack_regs.
* stmt.c (expand_asm_operands): Verify number of alternatives is in
range.
* Makefile.in (reg-stack.o): Depend on recog.h.
