Hi,
when looking for detected call argument type incompatibilities I
stumbled over a call to builtin_memcpy which originally was a call to
builtin_memset but simplify_builtin_call changed it to the former
without setting the gimple statement fntype. That's probably not a big
deal but since I know about it I thought I might as well make the
statement consistent with the following.
Bootstrapped and tested on x86-64-linux. OK for trunk?
Thanks,
Martin

* tree-ssa-forwprop.c (simplify_builtin_call): Set gimple call
fntype when switching to calling memcpy instead of memset.
