Thanks. I'll take a look.

One of the things that can be optimized is the insertion of PHI nodes. They are not strictly necessary when you do this type of replacement. Callers could have a choice. In the case of VRP, PHI nodes may provide more information at merge points, but I need to evaluate this.

Also, did you experiment whether a scheme like this can be used instead of ssa-into-ssa?


Diego.
