#10613: Mechanism for checking that we only enter single-entry thunks once -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.10.1 Component: Compiler | Operating System: Unknown/Multiple Keywords: | Type of failure: Other Architecture: | Blocked By: Unknown/Multiple | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- During this week's GHC call it came up that it would be nice to have a linting mechanism for verifying that we only enter single-entry thunks once, as currently this invariant appears to be completely unchecked. Currently we do not record whether a thunk is intended to be single-entry when we emit its code. Moreover, I don't believe there is any room for this left in the info table to record this fact. There are two ways I can think of accomodating this, * stealing a bit from the thunk type field * add a flags field to `StgDebugInfo` such that the lint requires the `debug` way As far as implementing the check itself, I think it should be rather straightforward. When we enter a thunk we simply want to check whether it is single-entry. If it is then we replace it with a special type of `BLACKHOLE`-like thunk which crashes the program (or merely emits a warning) on entry. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10613> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Trying to build GHC on sparc64 currently crashes with a SIGBUS (unaligned access). This is because sparc64 uses the C backend (only 32-bit sparc has native code gen), but is unaware that it can't perform unaligned accesses. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/12793> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Secondly, it says: "If you want to write your own good consumers or producers, look at the Prelude definitions of the above functions to see how to do so." However if you go to https://hackage.haskell.org/package/base-4.9.0.0/docs/Prelude.html and look at the source code for length you end up at https://hackage.haskell.org/package/base-4.9.0.0/docs/src/Data.Foldable.htm… which is not a good consumer. I think the User's Guide should be changed to replace "Prelude" with "https://hackage.haskell.org/package/base-4.9.0.0/docs/src/GHC.List.html". -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13000> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#11425: The GHC API doesn't provide a good hscTarget option for tooling -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: feature | Status: new request | Priority: high | Milestone: 8.2.1 Component: GHC API | Version: 7.10.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Tools like ghc-mod typically just want `TypecheckedModule`s. Sadly, the GHC API currently doesn't provide a good way to get at these in all cases (see this [https://github.com/DanielG/ghc-mod/issues/205|ghc-mod ticket]). Each of the options we offer are cursed with their own limitations (largely quoting from the ghc-mod ticket), == HscNothing == At first glance this looks like what you would want. But... * Pros * Doesn't generate code of any sort and is therefore rather lightweight * Cons * It lacks support for Template Haskell * Has trouble with `foreign export`s * [https://github.com/DanielG/ghc-mod/pull/145|Fails} to issue pattern match checker warnings == HscInterpreted == Okay, so `HscNothing` doesn't work. Maybe `HscInterpreted` is better? * Pros * Supports Template Haskell * Cons * Can't deal with unboxed tuples (#1257) * Slower as we need to produce unnecessary bytecode * Large memory footprint * Also can't deal with `foreign export`s == HscAsm == * Pros * Supports all compilable code * Cons * Slow * Produces `.o` files This is quite unfortunate. It seems like we need something in between `HscNothing` and `HscInterpreted` which is willing to use the interpreter to evaluate Template Haskell splices when necessary, but doesn't produce bytecode. Unfortunately it's unclear what to do about `foreign export` (but arguably most tools would be fine with some approximate representation). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11425> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
