RFC: "Native -XCPP" Proposal

glasgow-user - Wed, 05/06/2015 - 12:08pm
Hello *, As you may be aware, GHC's `{-# LANGUAGE CPP #-}` language extension currently relies on the system's C-compiler bundled `cpp` program to provide a "traditional mode" c-preprocessor. This has caused several problems in the past, since parsing Haskell code with a preprocessor mode designed for use with C's tokenizer has caused already quite some problems[1] in the past. I'd like to see GHC 7.12 adopt an implemntation of `-XCPP` that does not rely on the shaky system-`cpp` foundation. To this end I've created a wiki page https://ghc.haskell.org/trac/ghc/wiki/Proposal/NativeCpp to describe the actual problems in more detail, and a couple of possible ways forward. Ideally, we'd simply integrate `cpphs` into GHC (i.e. "plan 2"). However, due to `cpp`s non-BSD3 license this should be discussed and debated since affects the overall-license of the GHC code-base, which may or may not be a problem to GHC's user-base (and that's what I hope this discussion will help to find out). So please go ahead and

Looking for retainers of PINNED objects

glasgow-user - Wed, 04/29/2015 - 5:37am
Hi all, I'm profiling a fairly large program which seems to have a space leak. The heap profiling (-hc) shows that PINNED objects are accumulated over time. In order to check the retainers of the objects, I ran the retainer profiling. Unfortunately it didn't output anything with -hr -hcPINNED. Also, this is just a guess though, the retainer profiling without any filters (I mean just -hr) doesn't seem to include PINNED objects at all. Is there a way to check what retains the PINNED objects?

What’s the story with this? I tried to follow the instructions here: https://ghc.haskell.org/trac/ghc/wiki/SIMD <https://ghc.haskell.org/trac/ghc/wiki/SIMD> but I get Dominic Steinitz dominic< at >steinitz.org http://idontgetoutmuch.wordpress.com _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users< at >haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/glasgow-haskell-users

New gtk2hs 0.12.4 release

gtk2hs - Wed, 11/21/2012 - 12:56pm

Thanks to John Lato and Duncan Coutts for the latest bugfix release! The latest packages should be buildable on GHC 7.6, and the cairo package should behave a bit nicer in ghci on Windows. Thanks to all!
