      Implement the Strict language extension · 46a03fbe
      Adam Sandberg Eriksson authored
      Add a new language extension `-XStrict` which turns all bindings strict
      as if the programmer had written a `!` before it. This also upgrades
      ordinary Haskell to allow recursive and polymorphic strict bindings.
      See the wiki[1] and the Note [Desugar Strict binds] in DsBinds for
      specification and implementation details.

      Fix bootstrapping with GHC 7.10.1 · 54884220
      Ben Gamari authored
      Relying on CallStack being in GLASGOW_HASKELL >= 710 breaks
      bootstrappability with 7.10.1
      7.10.2 added the CallStack mechanism, and GHC already relies on this
      while being built. Unfortunately, it is enabled with "GLASGOW_HASKELL
      >= 710", which also applies to GHC 7.10.1, which does not have
      CallStack, and fails building the stage-1 compiler because the symbol
      is not found.
      This patch makes the CPP directive more strict, requiring **more than**
      7.10 instead of **at least**.

      Make 'error' include the CCS call stack when profiled · 8988be85
      Simon Marlow authored
      The idea here is that this gives a more detailed stack trace in two
      1. With `-prof` and `-fprof-auto`
      2. In GHCi (see #11047)
      Example, with an error inserted in nofib/shootout/binary-trees:
      $ ./Main 3
      Main: z
      CallStack (from ImplicitParams):
        error, called at Main.hs:67:29 in main:Main
      CallStack (from -prof):
        Main.check' (Main.hs:(67,1)-(68,82))
        Main.check (Main.hs:63:1-21)
        Main.stretch (Main.hs:32:35-57)
        Main.main.c (Main.hs:32:9-57)
        Main.main (Main.hs:(27,1)-(43,42))
        Main.CAF (<entire-module>)
      This doesn't quite obsolete +RTS -xc, which also attempts to display
      more information in the case when the error is in a CAF, but I'm
      exploring other solutions to that.
      Includes submodule updates.

      APIAnnotations:add Locations in hsSyn for layout · 2290c8bd
      Alan Zimmerman authored
      At the moment ghc-exactprint, which uses the GHC API Annotations to
      provide a framework for roundtripping Haskell source code with optional
      AST edits, has to implement a horrible workaround to manage the points
      where layout needs to be captured.
      These are
      To provide a more natural representation, the contents subject to layout

      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.
      Test Plan: validate with both settings of SplitSections
