Function Documentation

void add_c_test	(	const char *	,
		int
	)

Add an entry to the table of conditions. Used by genconditions and by read-rtl.c.

void add_predicate

(

struct pred_data *

)

void add_predicate_code	(	struct pred_data *	,
		enum	rtx_code
	)

void get_pattern_stats	(	struct pattern_stats *	ranges,
		rtvec	vec
	)

bool init_rtx_reader_args	(	int	,
		char **
	)

bool init_rtx_reader_args_cb	(	int	argc,
		char **	argv,
		bool(*)(const char *)	parse_opt
	)

The entry point for initializing the reader.

 Prepare to read input.   

 Start at 1, to make 0 available for CODE_FOR_nothing.   

 Process define_cond_exec patterns.   

 Process define_subst patterns.

int maybe_eval_c_test

(

const char *

)

If the C test passed as the argument can be evaluated at compile time, return its truth value; else return -1. The test must have appeared somewhere in the machine description when genconditions was run.

		int *
	)

struct pred_data* first_predicate

int insn_elision

Set this to 0 to disable automatic elision of insn patterns which can never be used in this configuration. See genconditions.c. Must be set before calling init_md_reader.
