--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
One of the main oddities is that gsi_remove (..., true) doesn't release the
stmt DEFs but remove_phi_node (..., true) does. The latter now also releases
the stmts memory. I think that having defs released controlled independently
on the actual stmt being freed is good, so eventually remove_phi_node (...,
true); could be replaced by release_defs (phi); remove_phi_node (..., true);
and gsi_remove (..., true); made to ggc_free the actual stmt (big fallout!
possibly "fix" by having a TO_RELEASE_STMTS like we have that SSA_NAME queue
for re-use).
