re PR c/66618 (Failure to diagnose non-constant initializer for static object with -O1)
PR c/66618
PR c/69960
c-family/
* c-common.h (c_fully_fold): Add LVAL argument defaulted to false.
c/
* c-parser.c (c_parser_omp_atomic): Pass true as LVAL to c_fully_fold
where needed.
* c-typeck.c (build_unary_op, build_modify_expr, build_asm_expr,
handle_omp_array_sections): Likewise.
(digest_init): Don't call decl_constant_value_for_optimization.
* c-tree.h (decl_constant_value_for_optimization): Removed.
* c-fold.c (c_fold_array_ref): New function.
(c_fully_fold_internal): Add LVAL argument, propagate it through
recursive calls. For VAR_P call decl_constant_value and
unshare if not LVAL and either optimizing or IN_INIT. Remove
decl_constant_value_for_optimization calls. If IN_INIT and not LVAL,
fold ARRAY_REF with STRING_CST and INTEGER_CST operands.
(c_fully_fold): Add LVAL argument, pass it through to
c_fully_fold_internal.
(decl_constant_value_for_optimization): Removed.
cp/
* cp-gimplify.c (c_fully_fold): Add LVAL argument, call
cp_fold_maybe_rvalue instead of cp_fold_rvalue and pass it !LVAL.
testsuite/
* gcc.dg/pr69960.c: New test.
* gcc.dg/pr66618.c: New test.
* gcc.dg/pr66618-2.c: New test.
