/* To-do flags for calls to update_ssa. */
/* Update the SSA form inserting PHI nodes for newly exposed symbols
and virtual names marked for updating. When updating real names,
only insert PHI nodes for a real name O_j in blocks reached by all
the new and old definitions for O_j. If the iterated dominance
frontier for O_j is not pruned, we may end up inserting PHI nodes
in blocks that have one or more edges with no incoming definition
for O_j. This would lead to uninitialized warnings for O_j's
symbol. */
#define TODO_update_ssa (1 << 7)

themselves or passes that need only to patch use-def and def-def
chains for virtuals (e.g., DCE). */

IDF is done. This is used by passes that need the PHI nodes for
O_j even if it means that some arguments will come from the default
definition of O_j's symbol (e.g., pass_linear_transform).
WARNING: If you need to use this flag, chances are that your pass
may be doing something wrong. Inserting PHI nodes for an old name
where not all edges carry a new replacement may lead to silent
codegen errors or spurious uninitialized warnings. */

the updating of virtual names to the generic updater. Since FUD
