[Gm2] latest git commit

[Gaius Mulley]

Hello,

here is the latest set of git commits to master, two bugs fixed
in the areas of ISO LENGTH and pim4 MOD DIV (for negative operands).

2017-06-08

  * Fixed pim4 and iso DIV and MOD bug reported by Ernst Bokkelkamp
    <address@hidden>, Benjamin Kowarsch and Xin Wang.
  * gm2/gm2-compiler/M2GenGCC.mod:  CodeDivM2, CodeModM2,
    FoldDivM2, FoldModM2, FoldDivCeil, CodeDivCeil, FoldModCeil
    CodeModCeil (New procedures).
  * gm2/gm2-compiler/M2Options.def:  GetISO, GetPIM, GetPIM2,
    GetPIM3, GetPIM4, GetPositiveModFloor (New procedure function
    definitions).
  * gm2/gm2-gcc/m2options.h:  define/export functions
    GetISO, GetPIM, GetPIM2, GetPIM3, GetPIM4, GetPositiveModFloor.
  * gm2/gm2-compiler/M2Options.mod: ensure that the default pim4
    setting is turned off if pim2, pim3 is selected.  GetISO, GetPIM,
    GetPIM2, GetPIM3, GetPIM4, GetPositiveModFloor (New procedure
    functions).
  * gm2/gm2-compiler/M2Quads.def:  DivM2Op, ModM2Op, DivCeilOp
    ModCeilOp (New quad operators).
  * gm2/gm2-compiler/M2Quads.mod:  removed unnecessary prototypes.
    MakeOp returns ModM2Op or DivM2Op for a modulus or div operator.
    Added new quad operators to the case statement selections.
  * gm2/gm2-gcc/m2expr.c:  include m2options.h.  BuildDivCeil,
    BuildModCeil, BuildDivM2, BuildModM2 (New functions).
    Much gnu coding standard reformatting has occurred.
  * gm2/gm2-gcc/m2expr.def:  define BuildDivM2, BuildModM2,
    BuildDivCeil, BuildModCeil.
  * gm2/gm2-gcc/m2expr.h:  define BuildDivM2, BuildModM2,
    BuildDivCeil, BuildModCeil.
  * gm2/mc/mcError.mod:  corrected dates.

2017-06-06

  * gm2/gm2-compiler/M2GenGCC.mod: (CodeLengthFunction) Call
    InternalError if op1 is a constant.
    (FoldLengthFunction) if op1 is a constant fold the
    result and remove the quadruple.
  * gm2/gm2-compiler/M2Quads.mod:  (BuildLengthFunction)
    check to see if parameter to length is a constant
    if so then use StandardFunctionOp otherwise
    call M2RTS_Length.  Fixes a bug reported by
    Ernst Bokkelkamp <address@hidden>.
  * gm2/gm2-compiler/SymbolTable.mod:  correct end procedure
    name PutConstIntoTypeTree.
  * gm2/gm2-gcc/m2expr.c:  many gnu coding standard changes.
  * gm2/mc/mcStream.mod:  (createTemporaryFile) create a per
    process temporary file name.
  * (mc) regenerated.
