* Implement -jsem: parallelism controlled by semaphoressheaf2023-04-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See https://github.com/ghc-proposals/ghc-proposals/pull/540/ for a complete description for the motivation for this feature. The `-jsem` option allows a build tool to pass a semaphore to GHC which GHC can use in order to control how much parallelism it requests. GHC itself acts as a client in the GHC jobserver protocol. ``` GHC Jobserver Protocol ~~~~~~~~~~~~~~~~~~~~~~ This proposal introduces the GHC Jobserver Protocol. This protocol allows a server to dynamically invoke many instances of a client process, while restricting all of those instances to use no more than <n> capabilities. This is achieved by coordination over a system semaphore (either a POSIX semaphore [6]_ in the case of Linux and Darwin, or a Win32 semaphore [7]_ in the case of Windows platforms). There are two kinds of participants in the GHC Jobserver protocol: - The *jobserver* creates a system semaphore with a certain number of available tokens. Each time the jobserver wants to spawn a new jobclient subprocess, it **must** first acquire a single token from the semaphore, before spawning the subprocess. This token **must** be released once the subprocess terminates. Once work is finished, the jobserver **must** destroy the semaphore it created. - A *jobclient* is a subprocess spawned by the jobserver or another jobclient. Each jobclient starts with one available token (its *implicit token*, which was acquired by the parent which spawned it), and can request more tokens through the Jobserver Protocol by waiting on the semaphore. Each time a jobclient wants to spawn a new jobclient subprocess, it **must** pass on a single token to the child jobclient. This token can either be the jobclient's implicit token, or another token which the jobclient acquired from the semaphore. Each jobclient **must** release exactly as many tokens as it has acquired from the semaphore (this does not include the implicit tokens). ``` Build tools such as cabal act as jobservers in the protocol and are responsibile for correctly creating, cleaning up and managing the semaphore. Adds a new submodule (semaphore-compat) for managing and interacting with semaphores in a cross-platform way. Fixes #19349
* Merge libiserv with ghciSylvain Henry2023-02-171-1/+0
| | | | | | | | | | `libiserv` serves no purpose. As it depends on `ghci` and doesn't have more dependencies than the `ghci` package, its code could live in the `ghci` package too. This commit also moves most of the code from the `iserv` program into the `ghci` package as well so that it can be reused. This is especially useful for the implementation of TH for the JS backend (#22261, !9779).

* Bump Haskeline and add exceptions as boot libraryBen Gamari2019-11-131-0/+1

| | | | | This moves all URL references to Trac tickets to their corresponding GitLab counterparts.
* Remove `parallel` as a submoduleAlec Theriault2019-02-161-1/+0
| | | | | | | | | | | `parallel` is used in exactly one place in the GHC tree: the T2317 test. It seems almost by accident that it is a submodule; libraries needed only for tests should net be included as submodules (see `QuickCheck`, `async`, `haskell98`, `regex-compat`, `utf8-string`, `vector` and more for examples). T2317 will now get run only when `parallel` is installed instead of `parallel` being required for the testsuite to run.
* Remove random submoduleBen Gamari2018-07-141-1/+0

* vectorise: Put it out of its miseryBen Gamari2018-06-021-5/+1
| | | | | | | | | | | | | | | | | | | | | Poor DPH and its vectoriser have long been languishing; sadly it seems there is little chance that the effort will be rekindled. Every few years we discuss what to do with this mass of code and at least once we have agreed that it should be archived on a branch and removed from `master`. Here we do just that, eliminating heaps of dead code in the process. Here we drop the ParallelArrays extension, the vectoriser, and the `vector` and `primitive` submodules.

* Add 'stm' package to the global package databaseHerbert Valerio Riedel2017-09-201-1/+1
| | | | | | | | | | | | | | | | | | This is a preparation for `haskeline` picking up a dependency on `stm` real soon now. See https://github.com/judah/haskeline/pull/61 for details. If we figure out a way to not bundle the libraries depended upon by the GHCi executable in the global package database (see #8919 for the original reason why we had to start bundling terminfo/haskeline in the first place) we can get rid of `stm` again... On the bright side, we were able to avoid uploading new `stm` releases for over two years already, so it shouldn't cause too much trouble if GHC imposes a strong preference on the `stm` package's version (this most likely will mostly affect Linux distributions & similiar). While at it, this also update the stm submodule to include relaxed bounds to allow the upcoming base-4.11 version.
* Bump mtl, parsec, text submodulesRyan Scott2017-08-141-2/+2

* Enable building Cabal with parsecHerbert Valerio Riedel2017-08-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Cabal's parser has been rewritten in terms of Parsec (which is not enabled yet in Cabal-2.0 by default, but can be enabled by a cabal flag). The plan for Cabal is to drop support for the non-parsec parser, so we need to prepare GHC to cope with new situation. However, this means that lib:Cabal requires three new library dependency submodules, - parsec - text - mtl What complicates matters is that we need to build `ghc-cabal` early on during the bootstrap phase which currently needs to invoke `ghc --make` directly. So these additional dependencies need to be integrated into the monolithic `ghc --make` invocation which produces the `ghc-cabal` executable.

* Hoopl: remove dependency on Hoopl packageMichal Terepeta2017-06-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This copies the subset of Hoopl's functionality needed by GHC to `cmm/Hoopl` and removes the dependency on the Hoopl package. The main motivation for this change is the confusing/noisy interface between GHC and Hoopl: - Hoopl has `Label` which is GHC's `BlockId` but different than GHC's `CLabel` - Hoopl has `Unique` which is different than GHC's `Unique` - Hoopl has `Unique{Map,Set}` which are different than GHC's `Uniq{FM,Set}` - GHC has its own specialized copy of `Dataflow`, so `cmm/Hoopl` is needed just to filter the exposed functions (filter out some of the Hoopl's and add the GHC ones) With this change, we'll be able to simplify this significantly. It'll also be much easier to do invasive changes (Hoopl is a public package on Hackage with users that depend on the current behavior) This should introduce no changes in functionality - it merely copies the relevant code.

* libffi via submoduleMoritz Angermann2017-05-111-1/+1
| | | | | | | | | | | | | | | | | | | This is rather annoying. I'd prefer to have a stable release to use. However libffi-3.2.1 has been released November 12, 2014, and libffi-4 is TBD. See also https://github.com/libffi/libffi/issues/296 The core reason for this change is that llvm changed the supported assembly to unified syntax, which libffi-3.2.1 does not use, and hence fails to compile for arm with llvm.
