I think it's a very special case and generally indirect calls should be avoided

(they are slower, have a cost on the branch target buffer, have an extra

dependency, increase register lifetime, etc.).



If profitable for a target the target should be un-propagated/CSEd late

during RTL optimizations.



Well, just my 2 cents.
