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. -- Conal _______________________________________________ Glasgow-haskell-users mailing list [hidden email] http://mail.haskell.org/cgi-bin/mailman/listinfo/glasgow-haskell-users |
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. -harendra On 15 September 2017 at 07:15, Conal Elliott <[hidden email]> wrote:

Did you try -fno-specialise? From: Glasgow-haskell-users [mailto:[hidden email]]

Thanks. I somehow didn't notice that flag. On Fri, Sep 15, 2017 at 3:23 AM, Simon Peyton Jones <[hidden email]> wrote:
