The only symbols that should need to be external are the ones for things accessable via the .hi files of the exposed modules. Though if basically every module is exposed then that would not help much. We should do this, but it wouldn't help in the case of the GHC package: as you say, every module is exposed. It would be good to have a per-module flag to say this is a hidden module, and then we could give the symbols the correct linker hint so that they don't populate the .so file's symbol table. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/5987#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

On Windows, detect if DLLs have too many symbols; trac #5987
The test isn't very pretty; it involves trawling through the
objdump -p output. I couldn't find an easier way, unfortuantely.

Don't build the ghc DLL on Windows; works around trac #5987
We also don't build DLLs for the dph-lifted-* packages as they depend
on ghc.

I discovered this when making changes in hoopl: a small change in hoopl causes recompilation of nearly every module in GHC. The reason is the way that GHC records dependencies across packages: rather than the fine-grained dependencies we get within a package, a dependency on a package module records only the ABI hash of the whole module. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/5987#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
