Hi Axel, When do you expect to publish an updated version of gtk2hs on hackage? On Thu, Nov 3, 2011 at 1:02 PM, Eugene Kirpichov wrote:

Hi, The actual thanks for tracking this down go to Vincent Hanquez for finding that we're doing a lot of gmp calls (and for making me aware of ltrace), and to Felipe Lessa for finding that this is caused by poor code generated for cFloatConv  :) Your changes look identical to those that I made in my copy.

Heh.

Guess what! A simple {-# INLINE cFloatConv #-} helped to the same extent!

Axel, I think this change should be pretty easy to incorporate, and it probably makes sense to inline all other functions in Types.chs too.

I've added INLINE pragmas to all these odd c2hs marshalling functions. Could you pull and check if I've done it correctly?

Thanks for tracking this down!

Axel

Would you like me to send the trivial darcs patch or the gtk2hs team will take care of this?

Hi Eugene,

did you try using the SPECIALIZE pragma? It is part of the Haskell 98 and Haskell 2010 specifications.

I don't think it's going to make any difference, as the core already have an specialized poor version.  See my first e-mail.
