dtrace discuss - Nov 2008 - dtrace and compiled haskell

Hi. I plan to develop a set of programs in haskell, which are to be compiled to
/native code/ (not bytecode) with the Glasgow Haskell Compiler. Is it possible
to use dtrace on compiled haskell programs?
Thanks.

If the Haskell compiler generates symbols then absolutely. If it  
doesn''t you might have some luck using the pid provider to trace  
specific addresses, but it''s going to be a bit of an uphill battle.

Sorry, I wanted to get in this earlier..

The quick way is to look at the output of ''nm'' on a compiled
executable, and see if you like the results.  You can trap external
calls to C functions, but my compiled haskell test didn''t show any
similar symbols for my pure haskell function definitions.
