static void gen_exp	(	rtx	,
		enum	rtx_code,
		char *
	)

static

Referenced by gen_exp(), gen_expand(), gen_insn(), gen_split(), and output_add_clobbers().

static void gen_exp ( )

static

Print a C expression to construct an RTX just like X,
   substituting any operand references appearing within.

References gen_exp(), gen_rtx_scratch(), HOST_WIDE_INT_PRINT_DEC_C, len, and print_code().

static void gen_expand ( rtx )

static

static void gen_expand ( )

static

Generate the `gen_...' function for a DEFINE_EXPAND.

static void gen_insn	(	rtx	,
		int
	)

static

static void gen_insn ( )

static

Generate the `gen_...' function for a DEFINE_INSN.

		enum	rtx_code
	)

static

Referenced by gen_exp().

static void gen_rtx_scratch ( )

static

static void gen_split ( rtx )

static

static void gen_split ( )

static

Like gen_expand, but generates insns resulting from splitting SPLIT.

References fatal(), free(), gen_exp(), get_pattern_stats(), insn_code_number, insn_index_number, pattern_stats::num_operand_vars, output_peephole2_scratches(), print_md_ptr_loc(), and SET.

static void output_add_clobbers ( )

static

Write a function, `add_clobbers', that is given a PARALLEL of sufficient
   size for the insn and an INSN_CODE, and inserts the required CLOBBERs at
   the end of the vector.

References clobber_list, clobber_ent::code_number, clobber_pat::first_clobber, gen_exp(), clobber_pat::insns, clobber_pat::next, clobber_ent::next, and clobber_pat::pattern.

Referenced by main().

static void output_added_clobbers_hard_reg_p ( )

static

Write a function, `added_clobbers_hard_reg_p' that is given an insn_code
   number that will have clobbers added (as indicated by `recog') and returns
   1 if those include a clobber of a hard reg or 0 if all of them just clobber
   SCRATCH.

References clobber_list, clobber_ent::code_number, clobber_pat::has_hard_reg, clobber_pat::insns, clobber_pat::next, and clobber_ent::next.

static void output_peephole2_scratches ( rtx )

static

Referenced by gen_split().

static void output_peephole2_scratches ( )

static

Generate code to invoke find_free_register () as needed for the
   scratch registers used by the peephole2 pattern in SPLIT.

References first.

static void print_code ( RTX_CODE )
