void add_c_test	(	const char *	,
		int
	)

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

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

The entry point for initializing the reader.

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 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.
