unsigned default_add_stmt_cost	(	void *	data,
		int	count,
		enum vect_cost_for_stmt	kind,
		struct _stmt_vec_info *	stmt_info,
		int	misalign,
		enum vect_cost_model_location	where
	)

By default, the cost model looks up the cost of the given statement kind and mode, multiplies it by the occurrence count, accumulates it into the cost specified by WHERE, and returns the cost added.

Statements in an inner loop relative to the loop being vectorized are weighted more heavily. The value here is arbitrary and could potentially be improved with analysis.

section* default_function_section	(	tree	decl,
		enum node_frequency	freq,
		bool	startup,
		bool	exit
	)

Choose named function section based on its frequency.

 Startup code should go to startup subsection unless it is
 unlikely executed (this happens especially with function splitting
 where we can split away unnecessary parts of static constructors.

 Similarly for exit.

You should have received a copy of the GNU General Public License along with GCC; see the file COPYING3. If not see http://www.gnu.org/licenses/. The migration of target macros to target hooks works as follows:

Create a target hook that uses the existing target macros to implement the same functionality.

Convert all the MI files to use the hook instead of the macro.

Repeat for a majority of the remaining target macros. This will take some time.

Tell target maintainers to start migrating.

Eventually convert the backends to override the hook instead of defining the macros. This will take some time too.

TBD when, poison the macros. Unmigrated targets will break at this point.

Note that we expect steps 1-3 to be done by the people that understand what the MI does with each macro, and step 5 to be done by the target maintainers for their respective targets.

Note that steps 1 and 2 don't have to be done together, but no target can override the new hook until step 2 is complete for it.

Once the macros are poisoned, we will revert to the old migration rules - migrate the macro, callers, and targets all at once. This comment can thus be removed at that point.

Return true if a parameter must be passed by reference. This version of the TARGET_PASS_BY_REFERENCE hook uses just MUST_PASS_IN_STACK.

tree std_gimplify_va_arg_expr	(	tree	valist,
		tree	type,
		gimple_seq *	pre_p,
		gimple_seq *	post_p
	)

The "standard" implementation of va_arg: read the value from the current (padded) address and increment by the (padded) size.

 When we align parameter on stack for caller, if the parameter
 alignment is beyond MAX_SUPPORTED_STACK_ALIGNMENT, it will be
 aligned at MAX_SUPPORTED_STACK_ALIGNMENT.  We will match callee
 here with caller.

 Hoist the valist value into a temporary for the moment.

 va_list pointer is aligned to PARM_BOUNDARY.  If argument actually
 requires greater alignment, we must perform dynamic alignment.

 If the actual alignment is less than the alignment of the type,
 adjust the type accordingly so that we don't assume strict alignment
 when dereferencing the pointer.

 Compute the rounded size of the type.

 Reduce rounded_size so it's sharable with the postqueue.

 Get AP.

     Small args are padded downward.

 Compute new value for AP.

bool targhook_float_words_big_endian ( void )

bool targhook_words_big_endian ( void )

Make some target macros useable by target-independent code.
