Highlights: - GHC supports the entire Haskell 2010 language plus a wide variety of extensions. - GHC has particularly good support for concurrency and parallelism, including support for Software Transactional Memory (STM). - GHC generates fast code, particularly for concurrent programs. Take a look at GHC's performance on The Computer Language Benchmarks Game. - GHC works on several platforms including Windows, Mac, Linux, most varieties of Unix, and several different processor architectures. - GHC has extensive optimisation capabilities, including inter-module optimisation. - GHC compiles Haskell code either directly to native code or using LLVM as a back-end. GHC 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. - GHC comes with several libraries, and thousands more are available on Hackage. %package compiler Summary: GHC compiler and utilities License: BSD Requires: gcc%{?_isa} Requires: %{name}-base-devel%{?_isa} = %{base_ver}-%{release} %if %{with haddock} Requires: %{name}-filesystem = %{version}-%{release} %else Obsoletes: %{name}-doc-index < %{version}-%{release} Obsoletes: %{name}-filesystem < %{version}-%{release} %endif %ifarch %{ghc_llvm_archs} %if 0%{?fedora} >= 34 Requires: llvm%{llvm_major} %else Requires: llvm = %{llvm_major} %endif %endif %description compiler The package contains the GHC compiler, tools and utilities.
