Cardinality

Simon Peyton Jones
I don't know how to account for that.  Make sure you are compiling everything with -dcore-lint.  I guess you are on a Mac?  I'm using 64-bit Linux.  Is it definitely ok with the old demand analyser?

Note for others: this is nofib/imaginary/integrate.

I run nofib and at some point I get the following output:

==nofib== integrate: time to run integrate follows...

If I remove integrate from the nofib Makefile, the rest of the benchmarks works just fine.

no, I don't.  That's odd.  How does it manifest for you?

Thank you.

I ran nofib myself too, and it seems to be fine, except that issue with imaginary/integrate.
Did you have that error when running nofib as well?

Hi Simon.

I tried to build from the `new-demand-to-merge` branch recently, and I got the following Lint error when building libraries/base/GHC/Event/Array.hs by a stage-1 compiler:

*** Core Lint errors : in result of Common sub-expression ***
<no location info>: Warning:
    In a case alternative: (GHC.ForeignPtr.ForeignPtr fo_s3mr :: GHC.Prim.Addr#,
                                                      ds1_s3mq :: GHC.ForeignPtr.ForeignPtrContents)
    Occurrence of a dead Id wild_s3ms

Any ideas, how it could be fixed, so I could integrate your changes into the cardinality branch and run the experiments?

Kind regards,
Ilya

Great, thank you.

Please, let me know when it's in the stable state, so I could implement the optimisation making use of single-used thunks (and it would not interfere with your changes).

Kind regards,
Ilya

I've been working on the code.  Will commit shortly.  Integrate seems ok, happily.
