re PR debug/83547 ((statement-frontiers) error: void value not ignored as it ought to be)
PR debug/83547
* tree-iterator.c (alloc_stmt_list): Start with cleared
TREE_SIDE_EFFECTS regardless whether a new STATEMENT_LIST is allocated
or old one reused.
c/
* c-typeck.c (c_finish_stmt_expr): Ignore !TREE_SIDE_EFFECTS as
indicator of ({ }), instead skip all trailing DEBUG_BEGIN_STMTs first,
and consider empty ones if there are no other stmts. For
-Wunused-value walk all statements before the one only followed by
DEBUG_BEGIN_STMTs.
testsuite/
* gcc.c-torture/compile/pr83547.c: New test.
