gnu: Add ghc-4. * gnu/packages/patches/ghc-4.patch: New file * gnu/local.mk (dist_patch_DATA): Add it. * gnu/packages/haskell.scm (ghc-4): New variable.
2022-01-28 12:34:32 -05:00
The GHC 4 runtime system was written before GCC 3.5 deprecated lvalue casts.
The runtime system's sources are littered with these casts, so early versions
of this patch were dedicated to rewriting those statements to a standards
compliant form. Unfortunately, this led to subtle breakage, so instead we
build with GCC 2.95.
Problematic for newer versions of GCC is also the assembly in the bundled
sources of GMP 2.0.2, which spans multiple lines without escaping line breaks.
TODO: We aren't yet using anything under ghc/compiler, so the patches there
aren't needed at this time. The intent was to ensure that the compiler
sources can be used even when they are interpreted by Hugs.
TODO: There are some more problems with the Haskell sources. Some files have
too many commas (both at the end of the line and at the beginning of the next
line). Others use a trailing hash, which Hugs doesn't understand.
TODO: Hugs doesn't understand "unsafe" in hslib/lang/Storable.lhs
