alloc_stmt_list()

tree alloc_stmt_list ( void )

extern

References ggc_alloc(), make_node(), stmt_list_cache, TREE_SET_CODE, TREE_SIDE_EFFECTS, TREE_TYPE, vec_safe_is_empty(), and void_type_node.

Referenced by append_to_statement_list_1(), copy_statement_list(), and create_task_copyfn().

append_to_statement_list()

void append_to_statement_list ( tree t, tree * list_p )

extern

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.   

References append_to_statement_list_1(), ggc_alloc(), TREE_CODE, and TREE_SIDE_EFFECTS.

append_to_statement_list_force()

void append_to_statement_list_force ( tree t, tree * list_p )

extern

Similar, but the statement is always added, regardless of side effects.   

References append_to_statement_list_1(), and NULL_TREE.

Referenced by gimplify_omp_affinity(), gimplify_omp_depend(), and gimplify_omp_for().

expr_first()

tree expr_first ( tree expr )

extern

Return the first expression in a sequence of COMPOUND_EXPRs, or in
a STATEMENT_LIST, disregarding DEBUG_BEGIN_STMTs, recursing into a
STATEMENT_LIST if that's the first non-DEBUG_BEGIN_STMT.   

References expr, expr_first(), ggc_alloc(), NULL_TREE, STATEMENT_LIST_HEAD, TREE_CODE, and TREE_OPERAND.

Referenced by expr_first().

expr_last()

tree expr_last ( tree expr )

extern

Return the last expression in a sequence of COMPOUND_EXPRs, or in a
STATEMENT_LIST, disregarding DEBUG_BEGIN_STMTs, recursing into a
STATEMENT_LIST if that's the last non-DEBUG_BEGIN_STMT.   

References expr, expr_last(), ggc_alloc(), NULL_TREE, STATEMENT_LIST_TAIL, TREE_CODE, and TREE_OPERAND.

Referenced by block_may_fallthru(), expr_last(), shortcut_cond_expr(), and tree_invalid_nonnegative_warnv_p().

expr_single()

tree expr_single ( tree expr )

extern

If EXPR is a STATEMENT_LIST containing just DEBUG_BEGIN_STMTs and
a single other stmt, return that other stmt (recursively).
If it is a STATEMENT_LIST containing no non-DEBUG_BEGIN_STMTs or
multiple, return NULL_TREE.
Otherwise return EXPR.

void free_stmt_list ( tree t )

extern

Referenced by tsi_link_after(), and tsi_link_before().

tsi_delink()

void tsi_delink ( tree_stmt_iterator * i )

extern

Remove a stmt from the tree list.  The iterator is updated to point to
the next stmt.
