Import ghc-8.4.4
GHC: The Glasgow Haskell Compiler.
The Glasgow Haskell Compiler is a robust, fully-featured, optimising
compiler for the functional programming language Haskell 98
(http://www.haskell.org). GHC compiles Haskell to either native code
or C. It implements numerous experimental language extensions to
Haskell, including concurrency, a foreign language interface, several
type-system extensions, exceptions, and so on. GHC comes with a
generational garbage collector, a space and time profiler, and a
comprehensive set of libraries.
This package provides the 8.4.x release series, which is the last
version that can bootstrap with 8.0.2. It will probably be removed
once we make a separate package for GHC 8.8.x and get enough bootstrap
kits for it.

+GHC requires itself to build, and unfortunately the only way to get a
+working GHC for a foreign target is to do a cross-compilation.
+
+In order to build a bootkit for a new platform, you need to manually
+set up a cross-building C compiler and binutils, libc, libterminfo,
+and libiconv for the target. Then you can follow instructions in
+https://gitlab.haskell.org/ghc/ghc/wikis/building/cross-compiling
+
+Once you get a working GHC for the target platform, install it
+somewhere in your PATH, run "cd lang/ghc84; make clean; make bootstrap"
+on the target platform and you'll have a bootkit for the target.
+
+--
+
+GHC in fact has never supported bootstrapping only with a C compiler.
+Prior to GHC 7, it had a thing called "HC source", which was a set of
+C source files compiled from Haskell source, but it wasn't actually
+cross-platform. It was because HC files were generated with many
+assumptions about the platform, such as the layout of libc structs,
+the size of off_t and time_t, byte-order, word size, etc.

+Suppress linker warnings about compatibility syscall wrappers by using
+"capi" instead of "ccall". In Haskell FFI, "ccall" is actually an
+interface to C ABI rather than C API. That is, GHC generates direct
+references to the symbol even if it's actually defined as a cpp macro
+or something like that, because GHC knows nothing about those macros
+in foreign headers. Hence the following warnings:
+
+ .../libHStime-1.4.0.1.a(CTimeval.o): In function `s1Kp_info':
+ (.text+0x2f): warning: warning: reference to compatibility
+ gettimeofday(); include <sys/time.h> to generate correct reference
+
+In other words, you can safely use "ccall" only when you are sure the
+symbol you want to import is actually a symbol in the ABI sense, which
+is not always the case for the POSIX API.
