Comment:

 Replying to [comment:2 rwbarton]:
 > Ideally, you would output a `__builtin_prefetch` call where `rw` is 0,
 `locality` is the argument of the `MO_Prefetch_Data` constructor, and
 `addr` comes from the `args` field of the `CmmUnsafeForeignCall`. That
 looks pretty easy to do, by adding another special case for `fn_addr` and
 sending `MO_Prefetch_Data _` to `__builtin_prefetch` in
 `pprCallishMachOp_for_C`.

 Please open a new task ticket if that is still needed. Commit
 896cee02e766c687a52cd75382bcfed64a623619 should have fixed the powerpc64
 build, so I'm closing this ticket if you agree.
