Hi,
I run into problems with operations having different types as operands
(similar to one causing string-opt failures I just fixed). These seems
to be commig from the fact that phi nodes already does have such a wrong
types after dominator optimizations because of
tree_ssa_useless_type_conversion
What is our expected behaviour here? Should simplifiers/expanders deal
with such a type differences or should we always care to re-invent the
nop?
