lang/ghc810: import ghc-8.10.4

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 8.10.x release series.

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/ghc88; 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.

# Security
#
# The runtime system of GHC (rts) tends to conflict with PaX MPROTECT
# because it needs to generate various kinds of code at run time. The
# RTS linker, whose job is to load *static* objects at run time,
# doesn't play nice with ASLR either because it relies on
# mmap(MAP_FIXED). This means most executables produced by GHC need
# them to be disabled. Perhaps we should patch rts/sm/Storage.c so
# that it uses ffi_closure_alloc(3) on every platform, not just Linux,
# and also drop support for static library loading and switch to
# dynamic libraries entirely.  (Partially done:
# https://gitlab.haskell.org/ghc/ghc/merge_requests/2498)

NOT_PAX_ASLR_SAFE+=	lib/${PKGNAME_NOREV}/bin/${f}
.endfor
# Additional note: Now that DYNAMIC_GHC_PROGRAMS is enabled by
# default, we no longer need to disable PaX ASLR because the RTS
# linker is not used... except for ghc-iserv. The program is launched
# when ghci is started with -fexternal-interpreter without
# -dynamic. Its purpose is to run non-PIC code from a dynamically
# linked ghci, and therefore still uses RTS linker. Also note that RTS
# linker requires PaX mprotect to be disabled too. This means that
# once the merge request mentioned above is merged to the upstream, we
# can at least enable PaX mprotect and PaX ASLR for all the
# executables except ghc-iserv and ghc-iserv-prof.

Enable Cabal's rpath overriding functionality on all the platforms
known to use ELF.

When a Cabal package which defins both a library and an executable is
to be built, GHC by default embeds an rpath to the *build* directory
into the executable. This may sound like a bug in GHC but is actually
not, because GHC doesn't know the fact that the said library is going
to be installed elsewhere. To overcome this issue, Cabal has a
functionality to disable the default rpath handling of GHC and
construct the correct set of rpaths... but only on certain platforms
for some reason.

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.
