/* Translating out of SSA sometimes requires inserting copies and
|
|
constant initializations on edges to eliminate PHI nodes.
|
|
|
|
In some cases those copies and constant initializations are
|
|
redundant because the target already has the value on the
|
|
RHS of the assignment.
|
|
|
|
We previously tried to catch these cases after translating
|
|
out of SSA form. However, that code often missed cases. Worse
|
|
yet, the cases it missed were also often missed by the RTL
|
|
optimizers. Thus the resulting code had redundant instructions.
|
|
|
|
This pass attempts to detect these situations before translating
|
|
out of SSA form.
|
|
|
|
The key concept that this pass is built upon is that these
|
|
redundant copies and constant initializations often occur
|
|
due to constant/copy propagating equivalences resulting from
|
|
COND_EXPRs and SWITCH_EXPRs.
|
|
|
|
We want to do those propagations as they can sometimes allow
|
|
the SSA optimizers to do a better job. However, in the cases
|
|
where such propagations do not result in further optimization,
|
|
we would like to "undo" the propagation to avoid the redundant
|
|
copies and constant initializations.
|
|
|
|
This pass works by first associating equivalences with edges in
|
|
the CFG. For example, the edge leading from a SWITCH_EXPR to
|
|
its associated CASE_LABEL will have an equivalency between
|
|
SWITCH_COND and the value in the case label.
|
|
|
|
Once we have found the edge equivalences, we proceed to walk
|
|
the CFG in dominator order. As we traverse edges we record
|
|
equivalences associated with those edges we traverse.
|
|
|
|
When we encounter a PHI node, we walk its arguments to see if we
|
|
have an equivalence for the PHI argument. If so, then we replace
|
|
the argument.
|
|
|
|
Equivalences are looked up based on their value (think of it as
|
|
the RHS of an assignment). A value may be an SSA_NAME or an
|
|
invariant. We may have several SSA_NAMEs with the same value,
|
|
so with each value we have a list of SSA_NAMEs that have the
|
|
same value. */
|
|
|
|
/* As we enter each block we record the value for any edge equivalency
|
|
leading to this block. If no such edge equivalency exists, then we

record NULL. These equivalences are live until we leave the dominator

subtree rooted at the block where we record the equivalency. */
