Hello Tim! I had a pet inlining ticket, which exposes some frivolous blowup: https://ghc.haskell.org/trac/ghc/ticket/8901 It has been closed because nobody really knows how to proceed. Anyway, I have just got the latest stats (appending to the ticket too) $ ls -l ./libraries/time/dist-install/build/Data/Time/Format.*o -rw-r--r-- 1 ggreif lb40 482568 Jan 12 16:24 ./libraries/time/dist-install/build/Data/Time/Format.dyn_o -rw-r--r-- 1 ggreif lb40 514776 Jan 12 16:24 ./libraries/time/dist-install/build/Data/Time/Format.o $ wc -l ./libraries/time/lib/Data/Time/Format.hs 254 ./libraries/time/lib/Data/Time/Format.hs $ strip ./libraries/time/dist-install/build/Data/Time/Format.*o $ ls -l ./libraries/time/dist-install/build/Data/Time/Format.*o -rw-r--r-- 1 ggreif lb40 201512 Jan 12 17:26 ./libraries/time/dist-install/build/Data/Time/Format.dyn_o -rw-r--r-- 1 ggreif lb40 187712 Jan 12 17:26 ./libraries/time/dist-install/build/Data/Time/Format.o $ ghc -e "187712/254" 739.0236220472441 As you can see a single line of Format.hs gets compiled to 739 stripped bytes. Maybe you are inclined to put this ticket on the Wiki list too? Cheers, Gabor On 1/11/17, Tim McGilchrist wrote:

Hi Matt,

I noted this down last year as something I wanted to work on for this year. Just letting you know that I'm starting to look at some of the easier tickets in that page.

Is there a good person or place to ask questions if I get stuck on anything?

Cheers, Tim

Dear Devs,

I've spent the last day looking at the inliner. In doing so I updated the wiki page about inlining to be a lot more useful to other people wanting to understand the intricacies and problems.

https://ghc.haskell.org/trac/ghc/wiki/Inlining

This looks like the perfect place for a newcomer to start working on GHC. The inliner is quite well contained, there are lots of open tickets with well-specified aims and lots of investigatory work to be done.

So the purpose of this email is:

1. Please tag any tickets relevant to inlining/specialisation with "Inlining" 2. Any newcomers keen to get involved should read the wiki page and see if they can tackle one of the tickets there.
