Hi all,
I have noticed that profiling in ghc-2.03 in combination with
-O or -O2 is not possible because of some problems at the
linking stage. Also it turns out that profiling combined with
tracing results in programs which don't output any trace at all.
Are the problems related to profiling an optimization resolved
in ghc-2.04? I have programs which havilly depend of
optimization. Without it, I have to say nasty things like
+RTS -H100M -K1M -hC -RTS. Whereas normally a heap of 16M
suffices.
Hi,
the problems you ran into with 2.03 have been resolved, although not
much testing of these bits was done before 2.04 went out the door.
Re: tracing when profiling, this is unknown to me - do you have an
example program that reproduces the behaviour?
