As per the GHC manual, it should be -fno-specialise for disabling all specialization, and -fno-cross-module-specialise for disabling only the specialization of imported INLINABLE functions. Both of these flags are "on" when using -O and -O2.

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.
