void lra ( FILE * )

rtx lra_create_new_reg	(	enum machine_mode	md_mode,
		rtx	original,
		enum reg_class	rclass,
		const char *	title
	)

   Analogous to the previous function but also inherits value of
   ORIGINAL.

rtx lra_eliminate_regs	(	rtx	x,
		enum machine_mode	mem_mode,
		rtx	insn
	)

   This function is used externally in subsequent passes of GCC.  It
   always does a full elimination of X.

void lra_finish_once ( void )

   Called once per compiler to finish LRA data which are initialize
   once.

static enum reg_class lra_get_allocno_class ( )

inlinestatic

   Return the allocno reg class of REGNO.  If it is a reload pseudo,
   the pseudo should finally get hard register of the allocno
   class.

void lra_init ( void )

   Initialize LRA whenever register-related information is changed.

void lra_init_elimination ( void )

   Entry function for initialization of elimination once per
   function.

References lra_dump_file, and print_elim_table().

void lra_init_once ( void )

   Called once per compiler to initialize LRA data once.

   True if the current function is too big to use regular algorithms
   in LRA. In other words, we should use simpler and faster algorithms
   in LRA.  It also means we should not worry about generation code
   for caller saves.  The value is set up in IRA.
