Writing a simple Core evaluator, having trouble with name lookups
by Christopher Done 01 Dec '18

01 Dec '18

Hi all, I'm attempting to make a simple evaluator for GHC core, but I'm not clear on how to reliably looking up names. I'm compiling each of ghc-prim, integer-simple and base with a patched version of GHC which performs an extra output step with the Core AST to a file for each module. Later, I load those files in. So for an input Haskell file like this: module Main (main,Foo(..)) where class Foo a where foo :: a -> Int instance Foo Int where foo x = x * x instance Foo Char where foo x = 99 main = print (foo (123 :: Int)) I have an output set of bindings like this: https://gist.github.com/chrisdone/cb05a77d3fcb081a4580b5f85289674a One thing that I immediately notice is that the names of things are completely non-unique, especially in generated names. So here are two implementations of the method "foo" for the class "Foo": ( Id {idStableName = "main:Main:$cfoo", idUnique = Unique 6989586621679010917}, ...) -- Int ( Id {idStableName = "main:Main:$cfoo", idUnique = Unique 6989586621679010923}, ...) -- Char So e.g. the instance for "Foo Int" refers to the above method implementation via its Unique (6989586621679010923): ( Id {idStableName = "main:Main:$fFooInt", idUnique = Unique 8214565720323784705} , CastE (VarE (Id { idStableName = "main:Main:$cfoo" , idUnique = Unique 6989586621679010923 <---- HERE }))) At first, I thought I would use the Unique associated with every Name to make a lookup. This is completely reliable within one GHC compilation, but I've read in the docs that it's not stable across multiple invocations? What does that mean for my case? Another thing I notice is that type-class methods are not generated at the core level. I have, for example, this method call that provides it the instance dictionary, (AppE (AppE (VarE (Id { idStableName = "main:Main:foo" , idUnique = Unique 8214565720323784707 <---- MISSING })) (TypE (Typ "Int"))) (VarE (Id { idStableName = "main:Main:$fFooInt" , idUnique = Unique 8214565720323784705 }))) But the "main:Main:foo" (8214565720323784707) is not produced in the CoreProgram, it seems. My compile step is very simple: compile :: GHC.GhcMonad m => GHC.ModSummary -> m [CoreSyn.Bind GHC.Var] compile modSummary = do parsedModule <- GHC.parseModule modSummary typecheckedModule <- GHC.typecheckModule parsedModule desugared <- GHC.desugarModule typecheckedModule let binds = GHC.mg_binds (GHC.dm_core_module desugared) pure binds It simply gets the bindings and that's all from the ModGuts. mg_binds :: !CoreProgram Two questions: 1) How do I recognize class methods when I see one, like the "main:Main:foo" above? Maybe this? isClassOpId_maybe :: Id -> Maybe Class Is an "op" what GHC calls type-class methods? 2) If I compile e.g. ghc-prim and that generates a binding Name with ID 123, and then I compile base -- will the ID 123 be re-used by base for something else, or will any reference to 123 in the compiled Names for base refer ONLY to that one in ghc-prim? In other words, when GHC loads the iface for ghc-prim, does it generate a fresh set of names for everything in ghc-prim, or does it load them from file? Cheers!

perf.haskell.org functional again
by Joachim Breitner 30 Nov '18

30 Nov '18

Hi, after a system upgrade to avoid weird linker errors, and after some fixes in the nofib submodule, http://perf.haskell.org/ghc is running again. I am collecting instruction counts instead of runtime, because the latter was just too often varying too wildly. I hope this will yield less false alarms. I am also running nofib with mode=fast. This way, building GHC, running the testsuite and nofib takes a bit over one hour. I hope this can keep up with y'all's commits (when it took 2h it couldn't). Now nothing of the setup requires a quiet dedicated machine, so if there is a need, we could move these builds into the cloud or into some CI infrastructure - but no changes are immediately planned. Enjoy, Joachim

Windows test failures

Ben, Phyx, and other CI folk 'sh validate -fast' still gives a lot of failures on Window. The output is below. I would be so good to get this to zero!

Kind inference
by Simon Peyton Jones 29 Nov '18

29 Nov '18

I have been working for longer than I care to admit on a significant refactoring of kind inference. I've just pushed it. It's a pretty big patch, which Richard and I have been discussing for some weeks. It validates, and fixes at least nine troublesome open tickets. But of course I could have made a mistake. Be vigilant. My: there will almost certainly be conflicts with your visible kind application patch, especially in tcInferApps. But that function has gotten substantially simpler in my patch so I don't think it'll be hard to fix things up. Phew! Simon

llvm way only tests?
by Gabor Greif 29 Nov '18

29 Nov '18

Hi all, what is the magic incantation for running tests only when the llvm tools (e.g. `opt`) are around? I am currently declaring the test as test('T15155l', [ only_ways(llvm_ways), ], run_command, ['$MAKE -s --no-print-directory T15155l']) but it won't be included neither in the optasm builds (which is okay) nor in the llvm builds (gets skipped unexpetedly) I looked at the other test which are declared similarly, and they behave just like mine. What I am doing wrong? Thanks, Gabor

Running IO function from RTS
by lonetiger＠gmail.com 26 Nov '18

26 Nov '18

Hi all, I’m looking for a way to initiate a call from the RTS into Haskell (base function) running and evaluating an IO function using the non-threaded RTS. For the threaded RTS I can use rts_evalIO with the RTS capability, but for the non-threaded I can’t find a way that doesn’t trigger the if (cap->in_haskell) { errorBelch("schedule: re-entered unsafely.\n" " Perhaps a 'foreign import unsafe' should be 'safe'?"); stg_exit(EXIT_FAILURE); } Clause in the scheduler. Taking a look at how the non-threaded I/O manager currently works on Windows, it seems that re-uses the TSO from the blocked thread doing the I/O call to give notifications back. This approach doesn’t work for me since the new I/O manager doesn’t block doing a foreign call boundary, instead It blocks in Haskell on an MVar, and I only want to wake up very specific threads. In short, does anyone know of a way to initialize an I/O operation from the non-threaded RTS? Thanks, Tamar
