[Gm2] latest cvs changes

[Gaius Mulley]

Hi,

here are the latest CVS changes (fixes to FOR loop checking, and
a fix to large set SHIFTs).


   * gm2/gm2-libs/SYSTEM.mod:  fixed an off by one bug in
     ShiftLeft and ShiftRight.
   * gm2.paranoid builds on LP64
   * gm2/patches/gcc/4.1.2/01.gaius_patch_gcc:  removed
     m2pp.o from being linked in with cc1 and cc1dummy.
   * gm2/gm2-compiler/M2GenGCC.mod:  (CodeEndFile) remove
     PopScope again as the quadruple coding ordering needs to
     be fixed before this code will work.  The CodeStartDefFile,
     CodeStartModFile, CodeEndFile need to be placed at the start
     and end of the module and collected in the CodeScope.
     Renamed CompilingMainModule to CompilingMainModuleStack.
   * gm2/gm2-compiler/M2Quads.mod:  (doConvert) New function.
     BuildForToByDo call doConvert to convert expressions e1 and
     e2 before they are used to calculate the iteration final
     value.  Fixes a bug reported by James Cox
     <address@hidden>.
     (testsuite/gm2/switches/check-all/run/pass/forcheck.mod).
   * gm2/m2pp.c:  new function (m2pp_integer).  m2pp_type and
     m2pp_simple_type call m2pp_integer.
     (m2pp_simple_expression)
     corrected '-' binary operator written.
   * gm2/bnf/m2-3.bnf:  removed unused procedure
     (CollectConstructor).
   * gm2/bnf/m2-h.bnf:  fixed ConstSetOrQualidentOrFunction
     to use ConstActualParameters.

the large set shift was an off by one bug - I'd be interested to hear
if the regression test  testsuite/gm2/isolib/run/pass/shift3.mod now
passes on other architectures.

regards,
Gaius
