#13282: Introduce fast path through simplifier for static bindings -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: feature | Status: new request | Priority: normal | Milestone: Component: Compiler | Version: 8.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Compile-time Unknown/Multiple | performance bug Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- It's not uncommon for early simplifier runs to float out a large number of "static data" bindings from a user program to the top-level. Here we will consider a top-level binding to be "static" if its RHS consists of a data constructor applied to zero or more other static bindings. This floating is quite helpful as static top-levels are represented easily as static code in object code. It also opens an interesting possibility: we know (with a few potential caveats discussed later) no further simplification of these bindings is possible. However, the simplifier currently does not take advantage of this latter fact: currently the simplifier will dutifully rebuild all bindings on every iteration. This work is wasted effort. I think it would be helpful to track the "static-ness" of top-level bindings and teach the simplifier and various analyses to ignore bindings so-marked. Also, there is one caveat here: it is currently possible for users to write rules whose LHSs are headed by a data constructor. This means that further simplification of the bindings which we deemed above as "static" **is** possible. There are two ways of dealing with this, a. Forbidding data cons in the head of a RULE's LHS b. Check the rule-base for matching rules matching a datacon as "static" -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13282> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #13299: Typecheck multiple modules at the same time

#13299: Typecheck multiple modules at the same time -------------------------------------+------------------------------------- Reporter: ezyang | Owner: (none) Type: feature | Status: new request | Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 (Type checker) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- angerman asked me to outline how one might go about fixing #1409 (mutually recursive modules without hs-boot). Here is the most recent plan based on #10681 and discussion with SPJ. **The general approach.** Traditionally, users write hs-boot files, which compile to hi-boot files that are subsequently used for compilation. The approach that SPJ and I would like to take is to replace this step with a new one that generates hi-boot files from hs files. Everything else otherwise stays the same. **More details.** Let's suppose we have A.hs and B.hs which import each other, A imports B using a `SOURCE` import, but no B.hs-boot is defined. We ask GHC to typecheck A.hs and B.hs together to produce hi-boot files for each of the modules. To implement this, we need both a new major mode for this operation (similar to `ghc -c`); and GhcMake needs to be adjusted to call this step on every SCC in the import graph, when one or more modules in the import graph do not have an hs-boot file. This part of the implementation is a bit annoying and was what thwarted me when I've made some stabs at this issue in the past. Probably the easiest thing to do initially is to fix up GhcMake to call your new frontend (you'll put it in `HscMain`) on every SCC. An easy way to check progress here is to get `ghc --make` to print out SCCs before it starts compiling them. GHC needs to learn how to typecheck multiple modules at the same time. Let's talk a little bit about how typechecking works today: by the time we are at `HscMain` we generally have a `ModSummary` per source module to be compiled. You pass the ModSummary to something like `tcRnModule` and you get back out a `TcGblEnv` containing the results of typechecking. Look at `hscIncrementalCompile`: if you're compiling a module proper, we desugar and optimize it properly (`finish`) and then create an interface for it; if we're only typechecking (`finishTypecheckOnly`) we go straight to generating the interface file after checking. All of these functions assume, of course, that only one module is being typechecked at a time. So you must break this assumption. This comes in multiple steps. First, the actual typechecking, `tcRnModule` needs to be adjusted. Notice `tcRnModule` takes a single `HsParsedModule`; now you need to feed it multiple parsed modules. You probably want a new function for this? What should this function look like? Trace further into `initTc`: notice that the `TcGblEnv` structure assumes that there is only one module being compiled at a time `tcg_mod` (and other modules). So this assumption needs to be broken. Now, trace into the main body of typechecking `tcRnModuleTcRnM`. Normally the way we go about doing things is we rename imports, and then we rename and typecheck declarations. Clearly each of your parsed modules needs to have their imports resolved separately; furthermore, they might import each other. This needs to be made to work. I think this will have to be totally reimplemented, because you are going to have to deal with cases like: {{{ module A(T) where import B(T) module B(T) where import A(T) }}} This is obviously nonsense and your algorithm needs to identify this and kill it. Once you've done this you should have a separate `tcg_rdr_env` for each of the parsed modules. `tcRnImports` sets up a pile of other variables in `TcGblEnv` too (see bottom) and I'm not sure what should be done with those. Now we need to rename and typecheck the top-level declarations. Renaming of imported entities should proceed straightforwardly because you set up the GlobalRdrEnv correctly, but you need to give the correct module to each of the top-level declarations. Maybe assume no Template Haskell for now because I have no idea how that's supposed to work. The crux of the matter, though, is that once you've renamed all of the declarations, you now need to compute SCCs over ALL of the modules, because how else are you going to typecheck two mutually recursive declarations over two modules. At this point the one-module assumption of TcGblEnv shouldn't be a problem anymore because when we're dealing with renamed source everything knows its name. There's a little bit more about the export list (`tcRnExports`) but you've probably already handled this to handle the recursive imports correctly. Finally, what you'll get out in the end is a big pile of types from DIFFERENT modules `tcg_type_env` (and all of the other things: instances, etc. Though, I guess if an instance is defined in one module of a recursive module loop, it should be in scope everywhere?!) So now in the final stage, serializing to interface files, we need to disentangle everything and put the declarations for each module into a separate interface file per module. Maybe best to have kept them separate to begin with. To conclude, adding support for typechecking multiple modules at once will probably involve rewriting large swathes of the renamer and top-level typechecking driver, but everything past that should basically be unchanged. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13299> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #13737: Have typechecking produce HsType Typechecked instead of Type

#13737: Have typechecking produce HsType Typechecked instead of Type -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Right now, there is an unfortunate lack of parallelism between expressions and types. When an expression is typechecked, it is transformed from `HsExpr Name` to `HsExpr TcId`. When a type is typechecked, it is transformed from `HsType Name` to `Type`. This arrangement has served us well enough for some time, but it has several drawbacks: - Validity checking is really meant to be done over user-written syntax. This bit when implementing #11715, when validity checking couldn't tell the difference between `Int => Int` (bad) and `Int -> Int` (good). There may be other opportunities for simplification by having the user-written syntax available. - The situation above extends to type-level declarations. That is, an `HsDecl Name` for a datatype goes straight to a `TyCon`, instead of to a typechecked form of source. This is problematic because it means that all of typechecking must happen ''twice''. The first is to figure out the kind of the `TyCon` (the is the `kc` pass); the actual result is discarded. Then, typechecking is repeated with the known `TyCon` kind; this pass should always succeed and is more like desugaring than typechecking. But all the constraint generation and solving happens again. - This second pass uses knot-tied `TyCon`s, leading to `Note [Type- checking inside the knot]` in !TsHsType. If we have a form of types in `HsSyn` that occurs ''after'' typechecking, we can fix the above problems, leading both to a runtime improvement (no double-checking type declarations) and code simplification (no more typechecking in the knot). This is a significant refactor, and it should proceed in at least two stages: one for just plain types, and one for type declarations. Note that we can't produce `HsType TcTyVar`, because `Name`s in `HsType Name` sometimes become `TyCon`s and sometimes become `TcTyVar`s. We really need `HsType (TyCon + TcTyVar)` or some such. But perhaps it would be better to wait until after refactoring with respect to the Trees That Grow paper. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13737> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

For example: "stopping thread ### (making a foreign call to function YYYY) So we could see which function and how much time is spent on that call. If creation of threads because of in-bound foreign calls (callbacks) have which callbacks are created for it will be very useful, too. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13529> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

This is because they are not marked as INLINABLE in the library itself. It'll be great if such functions in base are marked as INLINABLE so optimizator/inliner to generate more efficient code. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13689> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
