The Glasgow Haskell Compiler is a state-of-the-art, open source, compiler and
interactive environment for the functional language Haskell. Highlights:
* Supports the entire Haskell 2010 language plus a wide variety of
extensions.
* Has particularly good support for concurrency and parallelism, including
support for Software Transactional Memory (STM).
* Generates fast code, particularly for concurrent programs.
* Works on several platforms including FreeBSD, Windows, Mac, Linux, most
varieties of Unix, and several different processor architectures.
* Has extensive optimisation capabilities, including inter-module optimisation.
* Compiles Haskell code either directly to native code or using LLVM as a
back-end. It can also generate C code as an intermediate target for porting
to new platforms. The interactive environment compiles Haskell to bytecode,
and supports execution of mixed bytecode/compiled programs.
* Profiling is supported, both by time/allocation and various kinds of heap
profiling.
* Comes with several libraries, and thousands more are available on Hackage.
===> The following configuration options are available for ghc-9.4.6:
DOCS=on: Install HTML documentation
DYNAMIC=on: Add support for dynamic linking
GMP=on: Use GNU Multi-precision Library from Ports
PROFILE=on: Add support for performance profiling
====> Bootsrap using installed ghc
BOOT=off: Use installed GHC for bootstrapping
===> Use 'make config' to modify these settings
lang/ghc92: Reroll Hadrian bootstrap for real this time.
Fixes: c8d0965f210b5176103c0b8a81da352c9ae9e696
(cherry picked from commit c75f100932223d3a349490b70a29567156fa7667)
lang/ghc*: Add unconditional BUILD_DEPENDS on libgmp.
Rerolled bootstraps are now using GMP-backed Integer's, so make sure we can
run them on the build stage.
