Hello
Sorry for the uninformative subject, but I've got no less than 3
questions about profiling in ghc. Here we go
1) Can I profile my program if I don't have all the libraries it depends
on compiled with profiling?
ghc says it can't find profiling variants of this and that module in
other packages, when I try ghc -prof.
I managed to build all the dependencies with profiling, but that being a
necessity doesn't look good to me. Maybe there's a way to avoid that?
Moreover, as far as I could tell functions from those packages didn't
appear in the call graph after +RTS -p profiling.
2) Can I exclude a function from profiling? That probably means not
assigning a cost centre to it.
Typical case, I think. Database connect function is rather heavyweight
(regarding time) compared to the rest of the code, and it takes up to
98% of time. So the rest of the picture is less informative than it
could be.
3) Isn't it possible to have -p profiling data of the interrupted
(ctrl-c) program?
Thanks a lot!
