I'm getting this Framework failures: . ./perf/should_run/all.T [] (name 'stats_num_field' is not defined) I think it comes from this: commit fb669f51b3f2cae79511ac3d1c43939d951b1f69 Author: Tobias Decking <Tobias.Decking(a)gmail.com> Date: Thu Dec 6 15:32:18 2018 -0500 Add fusion rules for the zipWith functions in base (#15263) Simon

Cmm Memory Model (Understanding #15449)
by Travis Whitaker 07 Dec '18

07 Dec '18

Hello GHC Devs, I'm trying to get my head around ticket #15449 ( https://ghc.haskell.org/trac/ghc/ticket/15449) This gist of things is that GHC generates incorrect aarch64 code that causes memory corruption in multithreaded programs run on out-of-order machines. User trommler discovered that similar issues are present on PowerPC, and indeed ARMv7 and PowerPC support the same types of load/store reorderings. The LLVM code emitted by GHC may be incorrect with respect to LLVM's memory model, but this isn't a problem on architectures with minimal reordering like x86. I had initially thought that GHC simply wasn't emitting the appropriate LLVM fences; there's an elephant-gun-approach here ( https://github.com/TravisWhitaker/ghc/commits/ghc843-wip/T15449) that guards each atomic operation with a full barrier. I still believe that GHC is omitting necessary LLVM fences, but this change is insufficient to fix the behavior of the test case (which is simply GHC itself compiling a test package with '-jN', N > 1). It seems there's a long and foggy history of the Cmm memory model. Edward Yang discusses this a bit in his post here ( http://blog.ezyang.com/2014/01/so-you-want-to-add-a-new-concurrency-primiti…) and issues similar to #15449 have plagued GHC in the past, like #12469 ( https://ghc.haskell.org/trac/ghc/ticket/12469) Worryingly, GHC only has MO_WriteBarrier, whereas PowerPC and ARMv7 really need read, write, and full memory barriers. On ARM an instruction memory barrier might be required as well, but I don't know enough about STG/Cmm to say for sure, and it'd likely be LLVM's responsibility to emit that anyway. I'm hoping that someone with more tribal knowledge than I might be able to give me some pointers with regards to the following areas: - Does STG itself have anything like a memory model? My intuition says 'definitely not', but given that STG expressions may contain Cmm operations (via StgCmmPrim), there may be STG-to-STG transformations that need to care about the target machine's memory model. - With respect to Cmm, what reorderings does GHC perform? What are the relevant parts of the compiler to begin studying? - Are the LLVM atomics that GHC emits correct with respect to the LLVM memory model? As it stands now LLVM fences are only emitted for MO_WriteBarrier. Without fences accompanying the atomics, it seems the LLVM compiler could float dependent loads/stores past atomic operations. - Why is MO_WriteBarrier the only provided memory barrier? My hunch is that it's because this is the only sort of barrier required on x86, which only allows loads to be reordered with older stores, but perhaps I'm missing something? Is it plausible that Cmm simply needs additional barrier primitives to target these weaker memory models? Conversely, is there some property of Cmm that let's us get away without read barriers at all? Naturally, if I've got any of this wrong or are otherwise barking up the wrong tree, please let me know. Thanks for all your efforts! Travis Whitaker

RE: Windows test failures

At the end of the first test run it would have given a list of tests that failed and a line saying TEST=".... List of tests..." Copy that line and at the root of the checkout do make TEST="....

No threads? I have been trying to clean up the testsuite and there should be only 3 failing tests, two plugin tests with bad stdout and T10672_x64 which I am looking into. I have however noticed that the testsuite has become increasingly unstable under threads for some reason. I also haven't run trunk yet since last week so they could be new.. But rerunning the fails with no threads should give a better idea.

Guidelines for respectful communication
by Simon Peyton Jones 06 Dec '18

06 Dec '18

Friends As many of you will know, I have been concerned for several years about the standards of discourse in the Haskell community. I think things have improved since the period that drove me to write my Respect email<https://mail.haskell.org/pipermail/haskell/2016-September/024995.html>, but it's far from secure. We discussed this at a meeting of the GHC Steering Committee<https://github.com/ghc-proposals/ghc-proposals> at ICFP in September, and many of us have had related discussions since. Arising out of that conversation, the GHC Steering Committee has decided to adopt these Guidelines for respectful communication<https://github.com/ghc-proposals/ghc-proposals/blob/master/GRC.rst> We are not trying to impose these guidelines on members of the Haskell community generally. Rather, we are adopting them for ourselves, as a signal that we seek high standards of discourse in the Haskell community, and are willing to publicly hold ourselves to that standard, in the hope that others may choose to follow suit. We are calling them "guidelines for respectful communication" rather than a "code of conduct", because we want to encourage good communication, rather than focus on bad behaviour. Richard Stallman's recent post<https://lwn.net/Articles/769167/> about the new GNU Kind Communication Guidelines<https://gnu.org/philosophy/kind-communication.html> expresses the same idea. Meanwhile, the Stack community is taking a similar approach<https://www.snoyman.com/blog/2018/11/proposal-stack-coc>. Our guidelines are not set in stone; you can comment here<https://github.com/ghc-proposals/ghc-proposals/commit/373044b5a78519071b9a2…>. Perhaps they can evolve so that other Haskell committees (or even individuals) feel able to adopt them. The Haskell community is such a rich collection of intelligent, passionate, and committed people. Thank you -- I love you all! Simon

Cabal not updated after rebase?

Re: [Haskell] Treatment of unknown pragmas
by Artem Pelenitsyn 02 Dec '18

02 Dec '18

Hello Daniel, Annotations API was discussed earlier in this thread. Main points against are: Neil: Significant compilation performance penalty and extra recompilation. ANN pragmas is what HLint currently uses. Brandon: The problem with ANN is it's part of the plugins API, and as such does things like compiling the expression into the program in case a plugin generates code using its value, plus things like recompilation checking end up assuming plugins are in use and doing extra checking. Using it as a compile-time pragma is actually fairly weird from that standpoint. -- Best, Artem On Sat, 27 Oct 2018 at 22:12 Daniel Wagner <dmwit(a)dmwit.com> wrote: > I don't have a really strong opinion, but... isn't this (attaching > string-y data to source constructs) pretty much exactly what GHC's > annotation pragma is for? > ~d > > On Tue, Oct 16, 2018 at 3:14 PM Ben Gamari <ben(a)smart-cactus.org> wrote: > >> Vladislav Zavialov <vlad.z.4096(a)gmail.com> writes: >> >> > What about introducing -fno-warn-pragma=XXX?

typePrimRep invariants
by Csaba Hruska 01 Dec '18

01 Dec '18

Hi, I'd like to export the PrimRep of every binder and data con from Haskell modules. I have a modified GHC 8.6 which serializes the PrimRep for every binder during the compilation. It uses the *typePrimRep* function. When my customised GHC compiles the base library it always thows the following error for the *libraries/base/GHC/Err.hs* <https://github.com/grin-tech/ghc-grin/blob/master/ghc-8.6.2/libraries/base/…> module. 1. Does that mean that there is hidden requirement for typePrimRep input? 2. If so what are the restrictions? 3. Can you see anything in the Err module source code that could not be a proper input for typePrimRep function?
