Return a bitmap indexed by ipa_reference_var_uid for the static variables
that are *not* read during the execution of the function FN.  Returns
NULL if no data is available.

◆ ipa_reference_get_written_global()

bitmap ipa_reference_get_written_global ( struct cgraph_node * fn )

Return a bitmap indexed by ipa_reference_var_uid for the static variables
that are *not* written during the execution of the function FN.  Note
that variables written may or may not be read during the function
call.  Returns NULL if no data is available.

◆ ipa_reference_var_uid()

int ipa_reference_var_uid ( tree t )

Return ID used by ipa-reference bitmaps.  -1 if failed.
