Subject:     Drop original H8/300 support.  This should generate identical code for the remain... 
X-Git-Tag: upstream/12.2.0~16770
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=27c1afd533722e0dbc90562618a136653339cc49;p=platform%2Fupstream%2Fgcc.git

Drop original H8/300 support.  This should generate identical code for the remaining subtargets.  Defaults to H8/300H codegen

	* config/h8300/constraints.md (L and N): Simplify now that we're not
	longer supporting the original H8/300 chip.
	* config/h8300/elf.h (LINK_SPEC): Likewise.  Default to H8/300H.
	* config/h8300/h8300.c (shift_alg_qi): Drop H8/300 support.
	(shift_alg_hi, shift_alg_si): Similarly.
	(h8300_option_overrides): Similarly.  Default to H8/300H.  If
	compiling for H8/S, then turn off H8/300H.  Do not update the
	shift_alg tables for H8/300 port.
	(h8300_emit_stack_adjustment): Remove support for H8/300.  Simplify
	where possible.
	(push, split_adds_subs, h8300_rtx_costs): Likewise.
	(h8300_print_operand, compute_mov_length): Likewise.
	(output_plussi, compute_plussi_length): Likewise.
	(compute_plussi_cc, output_logical_op): Likewise.
	(compute_logical_op_length, compute_logical_op_cc): Likewise.
	(get_shift_alg, h8300_shift_needs_scratch): Likewise.
	(output_a_shift, compute_a_shift_length): Likewise.
	(output_a_rotate, compute_a_rotate_length): Likewise.
	(output_simode_bld, h8300_hard_regno_mode_ok): Likewise.
	(h8300_modes_tieable_p, h8300_return_in_memory): Likewise.
	* config/h8300/h8300.h (TARGET_CPU_CPP_BUILTINS): Likewise.
	(attr_cpu, TARGET_H8300): Remove.
	(TARGET_DEFAULT): Update.
	(UNITS_PER_WORD, PARM_BOUNDARY): Simplify where possible.
	(BIGGEST_ALIGNMENT, STACK_BOUNDARY): Likewise.
	(CONSTANT_ADDRESS_P, MOVE_MAX, Pmode): Likewise.
	(SIZE_TYPE, POINTER_SIZE, ASM_WORD_OP): Likewise.
	* config/h8300/h8300.md: Simplify patterns throughout.
	* config/h8300/t-h8300: Update multilib configuration.
