Use error_operand_p. (decl_constant_value): Adjust caller. * c-fold.c (c_fully_fold_internal): If in_init, pass true to decl_constant_value_1 as IN_INIT. Otherwise, punt if decl_constant_value returns initializer that has BLKmode or array type. (c_fully_fold_internal) <case COMPONENT_REF>: Fold if !lval. * gcc.dg/pr83801.c: New test.
