Function Documentation

tree alloc_stmt_list ( void  )

References memset().

Referenced by append_to_statement_list_1().

void append_to_statement_list ( ) 
   Add T to the end of the list container pointed to by LIST_P.
   If T is an expression with no effects, it is ignored.

Referenced by tsan_pass().

static void append_to_statement_list_1 ( )
static 
   A subroutine of append_to_statement_list{,_force}.  T is not NULL.

References alloc_stmt_list().

void append_to_statement_list_force ( ) 
   Similar, but the statement is always added, regardless of side effects.

References tree_stmt_iterator::container.

tree expr_first ( ) 
   Return the first expression in a sequence of COMPOUND_EXPRs,
   or in a STATEMENT_LIST.
tree expr_last ( ) 
   Return the last expression in a sequence of COMPOUND_EXPRs,
   or in a STATEMENT_LIST.
void free_stmt_list ( )

Referenced by tsi_link_before().

void tsi_delink ( ) 
   Remove a stmt from the tree list.  The iterator is updated to point to
   the next stmt.
void tsi_link_after ( ) 
   Links a statement, or a chain of statements, after the current stmt.  
     Die on looping.  
         Empty statement lists need no work.  
     Link it into the list.  
     Update the iterator, if requested.
void tsi_link_before ( ) 
   Links a statement, or a chain of statements, before the current stmt.  
     Die on looping.  
         Empty statement lists need no work.  
     Link it into the list.  
     Update the iterator, if requested.
