Inhibiting the specialiser?

[Simon Peyton Jones]

Did you try -fno-specialise?

Is there a GHC flag for inhibiting the specializer (but not all optimizations)? I'm seeing huge output from the Specialise phase killed at 4GB and growing. The output starts as follows:

Result size of Specialise
  = {terms: 29,639, types: 10,921,552, coercions: 4,425,185}

Sounds like a lot to me. Is it?. I get this behavior with -O2 and with -O.
