Function Documentation

compute_call_stmt_bb_frequency()

int compute_call_stmt_bb_frequency	(	tree	decl,
		basic_block	bb )

Computes the frequency of the call statement so that it can be stored in
cgraph_edge.  BB is the basic block of the call statement.

mark_load()

static bool mark_load ( gimple * stmt, tree t, tree , void * data )

static

Mark load of T.

mark_store()

static bool mark_store ( gimple * stmt, tree t, tree , void * data )

record_eh_tables()

static void record_eh_tables ( cgraph_node * node, function * fun )

static

Record all references we will introduce by producing EH tables
for NODE.

record_reference()

static tree record_reference ( tree * tp, int * walk_subtrees, void * data )

static

Walk tree and record all calls and references to functions/variables.
Called via walk_tree: TP is pointer to tree to be examined.
When DATA is non-null, record references to callgraph.

record_references_in_initializer()

void record_references_in_initializer	(	tree	decl,
		bool	only_vars )

Record references to functions and other variables present in the
initial value of DECL, a variable.
When ONLY_VARS is true, we mark needed only variables, not functions.

record_type_list()

static void record_type_list ( cgraph_node * node, tree list )

static

Record references to typeinfos in the type list LIST.
