      a good deal of salutory renaming · fd8d0411
      nr@eecs.harvard.edu authored
      I've renamed a number of type and data constructors within Cmm so that
      the names used in the compiler may more closely reflect the C--
      specification 2.1.  I've done a bit of other renaming as well.
      Highlights:
      
        CmmFormal and CmmActual now bear a CmmKind (which for now is a
                                                    MachHint as before)
        CmmFormals = [CmmFormal] and CmmActuals = [CmmActual]
        
        suitable changes have been made to both code and nonterminals in the
        Cmm parser (which is as yet untested)
      
        For reasons I don't understand, parts of the code generator use a
        sequence of 'formal parameters' with no C-- kinds.  For these we now
        have the types
          type CmmFormalWithoutKind   = LocalReg
          type CmmFormalsWithoutKinds = [CmmFormalWithoutKind]
      
        A great many appearances of (Tau, MachHint) have been simplified to
        the appropriate CmmFormal or CmmActual, though I'm sure there are
        more opportunities.
      
        Kind and its data constructors are now renamed to
           data GCKind = GCKindPtr | GCKindNonPtr 
        to avoid confusion with the Kind used in the type checker and with CmmKind.
      
      Finally, in a somewhat unrelated bit (and in honor of Simon PJ, who
      thought of the name), the Whalley/Davidson 'transaction limit' is now
      called 'OptimizationFuel' with the net effect that there are no longer
      two unrelated uses of the abbreviation 'tx'.

      fix for Simple9 · d22b4d8c

      No longer include non-indexed arguments

      By including non-indexed (additional) arguments,
      the lookup always fails.

      Fix zonking in mkExports · 08ea4e6d
      simonpj@microsoft.com authored
      I'd missed zonk, so that an error message for missing type signature

      Ian Lynagh authored
      They are now the same as hardtop/FPTOOLS_TOP_ABS, so use those instead.
      
      Also removed some substitutions of / for \, as we now use a Haskell
      program to find the top path, and it only makes paths with /s in.

      Cure space leak in coloring register allocator · b7f448a4
      Ben.Lippmeier@anu.edu.au authored
      We now do a deep seq on the graph after it is 'built', but before coloring.
      Without this, the colorer will just force bits of it and the heap will
      fill up with half evaluated pieces of graph from previous build/spill
      stages and zillions of apply thunks.

      FIX #1465, error messages could sometimes say things like "A.T doesn't match A.T" · 42181975
      Simon Marlow authored
      This turned out to be a black hole, however we believe we now have a
      plan that does the right thing and shouldn't need to change again.
      Error messages will only ever refer to a name in an unambiguous way,
      falling back to <package>:<module>.<name> if no unambiguous shorter
      variant can be found.  See HscTypes.mkPrintUnqualified for the
      details.
      
      Earlier hacks to work around this problem have been removed (TcSimplify).

      Improve GraphColor.colorScan · 1dd44153
      Ben.Lippmeier@anu.edu.au authored
      Testing whether a node in the conflict graph is trivially 
      colorable (triv) is still a somewhat expensive operation.
      
      When we find a triv node during scanning, even though we remove
      it and its edges from the graph, this is unlikely to to make the
      nodes we've just scanned become triv - so there's not much point
      re-scanning them right away.
      
      Scanning now takes place in passes. We scan the whole graph for
      triv nodes and remove all the ones found in a batch before rescanning
      old nodes.
      
      Register allocation for SHA1.lhs now takes (just) 40% of total
      compile time with -O2 -fregs-graph on x86
