--- Comment #9 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > Anyhow, if we do not want to clear those sizepos we could do > a walk_tree () looking for non-streamable parts and if found > reset it to plain PLACEHOLDER_EXPR. Note that I am also looking > for a fix suitable for GCC 8 (for the original referenced bug > motivating the change). Note that CONTAINS_PLACEHOLDER_P already does a recursive tree walking.
