      Only pretty-print binders in closed type families with -fprint-explicit-foralls · da792e47
      Ryan Scott authored
      Previously, we were unconditionally pretty-printing all type variable
      binders when pretty-printing closed type families (e.g., in the output
      of `:info` in GHCi). This threw me for a loop, so let's guard this behind
      the `-fprint-explicit-foralls` flag.

      Add backup url and sync support for Win32 tarball script · 71c3cea6
      Tamar Christina authored
      This imports @bgamari's sync script into the mirror script
      and adds a backup url for packages.
      The idea is that the URLs won't need updating when updating
      the tarballs from now on.
      It will first try haskell.org,
      failing that it'll try repo.msys2.org
      Test Plan: try new command `mk/get-win32-tarballs.sh sync`

      PPC NCG: Implement callish prim ops · 89a3241f
      Peter Trommler authored
      Provide PowerPC optimised implementations of callish prim ops.
      The generic implementation of quotient remainder prim ops uses
      a division and a remainder operation. There is no remainder on
      PowerPC and so we need to implement remainder "by hand" which
      results in a duplication of the divide operation when using the
      generic code.
      Avoid this duplication by implementing the prim op in the native
      code generator.
      Use PowerPC's instructions for long multiplication.
      Addition and subtraction
      Use PowerPC add/subtract with carry/overflow instructions
      MO_Clz and MO_Ctz
      Use PowerPC's CNTLZ instruction and implement count trailing
      zeros using count leading zeros
      Implement an algorithm given by Henry Warren in "Hacker's Delight"
      using PowerPC divide instruction. TODO: Use long division instructions
      when available (POWER7 and later).
      Test Plan: validate on AIX and 32-bit Linux

      This replaces the --with-* configure flags with the usual autoconf

      Revert "Remove special casing of Windows in generic files" · 66108864
      Ben Gamari authored
      This commit didn't consider the fact that binary distributions on Windows must
      have relative toolchain paths. This caused #13560.
      This reverts commit 48385cb2 (except for a
      helpful comment).

      Don't setProgramDynFlags on every :load · 914842e5
      Simon Marlow authored
      setProgramDynFlags invalidates the whole module graph, forcing
      everything to be re-summarised (including preprocessing) on every
      Looks like this was a bad regression in 8.0, but we didn't notice
      because there was no test for it.  Now there is!

      * validate
      * new unit test
