      Lowercase windows imports · 4b228768
      Moritz Angermann authored
      While windows and macOS are currently on case-insensitive file
      systems, this poses no issue on those.  When cross compiling from
      linux with a case sensitive file system and mingw providing only
      lowercase headers, this in fact produces an issue.  As such we just
      lowercase the import headers, which should still work fine on a
      case insensitive file system and also enable mingw's headers to
      be usable porperly.

      Rip out object splitting · 37f257af
      Ben Gamari authored
      The splitter is an evil Perl script that processes assembler code.
      Its job can be done better by the linker's --gc-sections flag. GHC
      passes this flag to the linker whenever -split-sections is passed on
      the command line.
      This is based on @DemiMarie's D2768.

      Release console for ghci wrapper · 3ec579d5
      Tamar Christina authored
      It seems the call that caused issues with the gcc wrapper before
      was needed for the ghci wrapper in order for the child process
      to be the one handling console events.
      This code slightly refactors the wrappers to make sure only ghci
      calls FreeConsole and nothing else.

      Implement split-sections support for windows. · bd4fdc6a
      Tamar Christina authored
      Initial implementation of split-section on Windows.
      This also corrects section namings and uses the platform
      convention of `$` instead of `.` to separate sections.
      Implementation is based on @awson's patches to binutils.
      Binutils requires some extra help when compiling the libraries
      for GHCi usage. We drop the `-T` and use implicit scripts to amend
      the linker scripts instead of replacing it.
      Because of these very large GHCi object files, we need big-obj support,
      which will be added by another patch.

      Revert "Remove the Windows GCC driver." · 58c781da
      Simon Peyton Jones authored
      This reverts commit d6cecde5.
      The patch broke Simon PJ's Windows build, becuase he didn't
      have (and should not need) a separate msys2 gcc.
      Following an exchange on the ghc-devs list, Tamar wrote
        Oops, sorry, didn’t notice it because both mine and harbormaster’s
        msys2 have separate GCCs installed as well.
        I don’t see an easy fix that would also work for end user Configure
        based cabal installs. So I think I’ll have to go back to the drawing
        board for this one.
        You can just leave it reverted.

      Remove the Windows GCC driver. · d6cecde5
      Tamar Christina authored
      This patch drops the GCC driver and instead moves
      the only remaining path that we need to keep for
      backwards compatibility to the settings file.
      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.

      Fix Windows GCC driver · 4b673e80
      Tamar Christina authored
      In Windows 10 Insiders build 15019+ which will probably be released
      mainstream somewhere this year Microsoft seems to have started being
      stricter with API calls.
      The call to `FreeConsole` just after `CreateProcess` is making Windows
      treat the process
      as an interactive process. In which case it tries to use the `Desktop
      session` but fails resulting
      in the cryptic error reported.
      I don't understand why the call to `FreeConsole` was there and it
      doesn't seem to be needed,
      so removed.
      This fixes #13411

      Properly detect MinTTY when running GHCi on Windows · 6fe9b057
      Ryan Scott authored
      Before, we detecting the presence of MinTTY on Windows in a very
      imprecise way: by checking if the `_` environment variable was set. Not
      only is this easy to circumvent, but it also yields false positives on
      terminals like ConEmu.
      This changes the test to use the `GetFileInformationByHandleEx` function
      instead, which provides a far more accurate check for MinTTY's presence.
      I've tested this on PowerShell, MSYS2, Cygwin, ConEmu, and Git Bash, and
      it does the right thing on each one.
      Fixes #12958.

      Implement function-sections for Haskell code, #8405 · 4a32bf92
      olsner authored
      This adds a flag -split-sections that does similar things to
      -split-objs, but using sections in single object files instead of
      relying on the Satanic Splitter and other abominations. This is very
      similar to the GCC flags -ffunction-sections and -fdata-sections.
      The --gc-sections linker flag, which allows unused sections to actually
      be removed, is added to all link commands (if the linker supports it) so
      that space savings from having base compiled with sections can be
      Supported both in LLVM and the native code-gen, in theory for all
      architectures, but really tested on x86 only.
      In the GHC build, a new SplitSections variable enables -split-sections
      for relevant parts of the build.

      Upgrade GCC to 5.2.0 for Windows x86 and x86_64 · 7b211b4e
      Tamar Christina authored
      This patch does a few things
      - Moved GHC x86 to MinGW-w64 (Using Awson's patch)
      - Moves Both GHCs to MSYS2 toolchains
      - Completely removes the dependencies on the git tarball repo
        - Downloads only the required tarball for the architecture for
          which we are building
        - Downloads the perl tarball is missing as well
        - Fixed a few bugs in the linker to fix tests on Windows
      The links currently point to repo.msys2.org and GitHub, it might be
      more desirable to mirror them on
      http://downloads.haskell.org/~ghc/mingw/ as with the previous patch
      For more details on what the MSYS2 packages I include see #10726
      (Awson's comment). but it should contain all we need
      and no python or fortran, which makes the uncompressed tar a 1-2
      hundreds mb smaller.
      The `GCC 5.2.0` in the package supports `libgcc` as a shared library,
      this is a problem since
      when compiling with -shared the produced dll now has a dependency on
      To solve this the flag `-static-libgcc` is now being used for all GCC
      calls on windows.

      the baseline.

      Rename _closure to _static_closure, apply naming consistently. · 35672072
      Edward Z. Yang authored
      In preparation for indirecting all references to closures,
      we rename _closure to _static_closure to ensure any old code
      will get an undefined symbol error.  In order to reference
      a closure foobar_closure (which is now undefined), you should instead
      use STATIC_CLOSURE(foobar).  For convenience, a number of these
      old identifiers are macro'd.
      Across C-- and C (Windows and otherwise), there were differing
      conventions on whether or not foobar_closure or &foobar_closure
      was the address of the closure.  Now, all foobar_closure references
      are addresses, and no & is necessary.
      CHARLIKE/INTLIKE were not changed, simply alpha-renamed.
