◆ gen_split()

static void gen_split ( md_rtx_info * info )

static

Similar but scan a define_split.

References md_rtx_info::def, i, max_insns_per_split, walk_insn_part(), XVECEXP, and XVECLEN.

Referenced by main().

◆ main()

int main	(	int	argc,
		const char **	argv )

◆ walk_insn_part()

static void walk_insn_part	(	rtx	part,
		int	recog_p,
		int	non_pc_set_src )

static

RECOG_P will be nonzero if this pattern was seen in a context where it will
be used to recognize, rather than just generate an insn.

NON_PC_SET_SRC will be nonzero if this pattern was seen in a SET_SRC
of a SET whose destination is not (pc).
