llvm-mirror/test/Transforms/InstCombine/ptr-int-cast.ll
Chris Lattner aabd3eeeff canonicalize inttoptr and ptrtoint instructions which cast pointers
to/from integer types that are not intptr_t to convert to intptr_t
then do an integer conversion to the dest type.  This exposes the
cast to the optimizer.
