      Deserialize all function TypeReps · 19ca2cab
      David Feuer authored
      Previously, we could only deserialize `TypeRep (a -> b)` if
      both `a` and `b` had kind `Type`. Now, we do it regardless of
      their runtime representations.

      Name TypeRep constructor fields · 3c8e55ce
      David Feuer authored
      Give `TypeRep` constructor fields names, and use them when pattern
      matching and constructing values. This is a bit verbose, but makes
      it obvious which field means what.

      llvmGen: Pass vector arguments in vector registers by default · 15f788f5
      Ben Gamari authored
      Earlier this year Edward Kmett requested [1] that we enable passing of
      vector values in vector registers by default. The GHC calling convention
      changes have been in LLVM for a number of years now so let's just flip
      the switch.

      CmmSink: Use a IntSet instead of a list · 43537568
      alexbiehl authored
      CmmProcs which have *lots* of local variables take a considerable
      amount of time in CmmSink. This was noticed by @tdammers in #7258
      while compiling files with large records (~200-400 fields).

      rts/PrimOps.cmm: add declaration for heapOverflow closure · 51321cf2
      Sergei Trofimovich authored
      Before the change UNREG ghc build failed as:
      ```
        rts_dist_HC rts/dist/build/PrimOps.o
      /tmp/ghc2370_0/ghc_4.hc: In function 'stg_newByteArrayzh':
      
      /tmp/ghc2370_0/ghc_4.hc:26:13: error:
           error: 'base_GHCziIOziException_heapOverflow_closure'
               undeclared (first use in this function)
           R1.w = (W_)&base_GHCziIOziException_heapOverflow_closure;
                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

      26 | R1.w = (W_)&base_GHCziIOziException_heapOverflow_closure;
         |             ^
      ```
      
      It's an UNREG-specific failure because C backend always requires
      declarations to be known.
      
      Added missing declaration.

      Ben Gamari authored
      Unfortunately this (ironically) ended up breaking bindist testing since
      we didn't have a package-data.mk. Unfortunately there is no easy way to
      fix this.
      
      This reverts commit 1e9f90af.
