      configure: Make sphinx-build version test work on recent versions · 533d3451
      Jens Petersen authored
      On Fedora: `/usr/libexec/sphinx-build --version` outputs `sphinx-build
      1.7.2`.  In bindir we actually have sphinx-build-2 and sphinx-build-3
      (python2 and python3 versions), which output `sphinx-build-2 1.7.2` and
      `sphinx-build-3 1.7.2` respectively.  Dunno what version others are
      using but at least this change should works for most versions I suppose.

      Add HeapView functionality · ec22f7dd
      patrickdoc authored
      This pulls parts of Joachim Breitner's ghc-heap-view library inside GHC.
      The bits added are the C hooks into the RTS and a basic Haskell wrapper
      to these C hooks. The main reason for these to be added to GHC proper
      is that the code needs to be kept in sync with the closure types
      defined by the RTS. It is expected that the version of HeapView shipped
      with GHC will always work with that version of GHC and that extra
      functionality can be layered on top with a library like ghc-heap-view
      distributed via Hackage.

      Remove MAX_PATH restrictions from RTS, I/O manager and various utilities · 4de585a5
      Tamar Christina authored
      Summary:
      This shims out fopen and sopen so that they use modern APIs under the hood
      along with namespaced paths.
      
      This lifts the MAX_PATH restrictions from Haskell programs and makes the new
      limit ~32k.
      
      There are only some slight caveats that have been documented.
      
      Some utilities have not been upgraded such as lndir, since all these things are
      different cabal packages I have been forced to copy the source in different places
      which is less than ideal. But it's the only way to keep sdist working.

      Adds rts/rts.cabal.in file · 5dea62fb
      Moritz Angermann authored
      This is in preparation for cabalification of the `rts`. To be actually
      able to parse this file, a rather recent Cabal is required. One after
      commit 357d49d of haskell/cabal. The relevant PR to support the new
      `asm-sources` and `cmm-sources` is haskell/cabal/pull/4857.
      
      Not that this does *not* allow cabal to build the RTS. It does however
      provide enough information such that cabal can `copy` and `register`
      the package properly in the package database, if all the build
      artifacts have been build properly.
      
      As such it does not require any custom handling of the `rts` package.
      As the rts as well as all the other packages built by the GHC built
      system are built outside of cabal anyway.

      Clean up opt and llc · 22733532
      Moritz Angermann authored
      The LLVM backend shells out to LLVMs `opt` and `llc` tools. This clean
      up introduces a shared data structure to carry the arguments we pass to
      each tool so that corresponding flags are next to each other. It drops
      the hard coded data layouts in favor of using `-mtriple` and have LLVM
      infer them. Furthermore we add `clang` as a proper tool, so we don't
      rely on assuming that `clang` is called `clang` on the `PATH` when using
      `clang` as the assembler.  Finally this diff also changes the type of
      `optLevel` from `Int` to `Word`, as we do not have negative optimization
      levels.

      Add gen-dll as replacement for dll-split · 5f6a8204
      Tamar Christina authored
      Summary:
      This tool can be used to generate dll's for any list of object files
      given to it. It will then repartition them automatically to fit within
      a dll and generates as many dll's as needed to do this. Cyclic dependencies
      between these generated dlls are handle automatically so there is no need
      to tell it how to partition.
      
      It is also a lot more general than `dll-split` as it is able to split any
      package not just `libGHC`. It also uses a trick using GNU style import libraries
      to hide the splitting from the rest of the pipeline. Which means come linking time
      you don't need to know which dll contains what symbol or how many split dlls were
      created.
      
      The import libraries are by default created with libtool. However since libtool is BFD
      based it is very slow. So if present and detected by configure the `genlib` tool
      from the msys2 project is used. This makes a difference of about ~45 minutes when compiling.
      
      To install `genlib` run `pacman -Sy mingw-w64-$(uname -m)-tools-git`.

      Enable building Cabal with parsec · 36fe21aa
      Herbert Valerio Riedel authored
      Cabal's parser has been rewritten in terms of Parsec (which is not
      enabled yet in Cabal-2.0 by default, but can be enabled by a cabal
      flag). The plan for Cabal is to drop support for the non-parsec parser,
      so we need to prepare GHC to cope with new situation.
      
      However, this means that lib:Cabal requires three new library
      dependency submodules,
      
       - parsec
       - text
       - mtl
      
      What complicates matters is that we need to build `ghc-cabal` early on
      during the bootstrap phase which currently needs to invoke `ghc --make`
      directly. So these additional dependencies need to be integrated into
      the monolithic `ghc --make` invocation which produces the `ghc-cabal`
      executable.

      Add -fuse-ld flag to CFLAGS during configure · 960918bd
      Ben Gamari authored
      The decisions made by configure later in the script may depend upon the
      linker used. Consequently, it is important that configure uses the same
      linker as GHC will eventually use.
      
      For instance, on Nix I found that a program requiring `libpthread` would
      link fine with only `-lrt` when linked with BFD ld. However, with gold
      we needed to explicitly provide the `-lpthread` dependency. Presumably
      the former would happily loaded any `NEEDED` libraries whereas the
      latter wants them explicitly given. Regardless, since `configure`'s
      `NEED_PTHREAD_LIB` check didn't use the `-fuse-ld` flag that GHC would
      eventually use, we inferred the wrong value, resulting in link errors
      later in the build.

      configure: Coerce gcc to use $LD instead of system default · 625143f4
      Ben Gamari authored
      The configure script will now try to coerce gcc to use the linker
      pointed to by $LD instead of the system default (typically bfd ld).
      Moreover, we now check for `ld.gold` and `ld.lld` before trying `ld`.
      
      The previous behavior can be reverted to by using the new

      On my machine gold seems to trigger an apparent infelicity in
      constructor behavior, causing T5435_asm to fail. I've opened #13883 to

      Summary:
      This patch drops the GCC driver and instead moves
      the only remaining path that we need to keep for

      It also generalizes the code that expands `$TopDir`
      so it can expand it within any location in the string
      and also changes it so `$TopDir` is expanded only
      after the words call because `$TopDir` can contains
      spaces which would be horribly broken.
