Hi Gaius,

with your changes all my code is compiling. Still I have to fix some linker 
problems before I start debugging....

Many thanks, Georg

Hello,

here are the latest changes made to gm2 on the trunk.  In summary
there are bug fixes to allow:

  (i)   'a' to be passed as an actual parameter to a formal parameter
         ARRAY [0..19] OF CHAR.  Also allows smaller constant
         strings to be passed which are nul padded.
  (ii)   assignment of record, and array types to LOC, BYTE, WORD
         providing that the sizes match.
  (iii)  valgrind to execute cc1gm2 without complaining about
         uninitialised values.  Read missing initialisations added.

regards,
Gaius


* gm2/examples/pge/examples/exampleBoxes.py:  much more debugging
  added.
* gm2/examples/pge/pge.py:  more debugging added.  Also correct
  lack of initialiser bugs.  Many diagnostics added.
* gm2/examples/pge/pgeif.def:  added ValueOutOfRange exception.
* gm2/examples/pge/pgeif.i:  added skip_until procedure.
* gm2/examples/pge/pgeif.mod:  (check_range) New function
  procedure.  get_xpos, get_ypos, box, poly3, poly4, poly5
  and poly6 all use check_range to check parameter values.
* gm2/examples/pge/twoDsim.mod:  added more trace information
  and test for object deletion.
* gm2/gm2-compiler/M2Base.mod:  added two more metatypes, rec
  and array.  Check for these meta types and add their
  characteristics into the assignment and expression matrices.
  This allows ARRAY and RECORD of the correct size to be compatible
  with WORD, BYTE, LOC etc.
* gm2/gm2-compiler/M2GCCDeclare.mod:  use BuiltinsLocation during
  the construction of the base types.
* gm2/gm2-compiler/M2GenGCC.mod:  added internal debugging.
  (CodeIndirectCall) skip type aliases for the return type.
* gm2/gm2-compiler/M2Scope.mod:  added internal debugging.
* gm2/gm2-compiler/SymbolTable.mod:  added missing initialisation
  for ScopeQuad.  This allows cc1gm2 to be run without errors by
  valgrind.
* gm2/gm2-gcc/m2convert.c:  convert_char_to_array (New function).
  convert_string_to_array (New function).  BuildConvert changed
  to detect whether a const lit char or string is required to be
  converted into a fixed string length.  This fixes a bug reported.
* gm2/gm2-gcc/m2statement.c:  tidied up code and fixed bug in
  (BuildReturnValueCode).  This fixes a bug exposed by
  testsuite/gm2/pim/pass/typeequiv.mod.
* gm2/gm2-gcc/m2type.c:  (BuildArrayStringConstructor) now adds
  multiple nuls to the end of a string if length exceeds string.
* gm2/gm2-libs/MemUtils.def:  tidied up formatting.
* gm2/p2c/p2c-src/src/pexpr.c:  fixed bug so that constant strings
  have a LOW indice of 0 not 1.
* gm2/pim/pass/typeequiv.mod:  corrected date.
* gm2/pim/pass/typeequiv2.mod:  corrected date.
* gm2/pim/pass/typeequiv3.mod:  corrected date.

* gm2/examples/pge/GC.mod:  (gdbif) imported to aid debugging.
  Initialised callbacks to NIL (bugfix).
* gm2/examples/pge/twoDsim.mod:  removed debugging hook.
* gm2/examples/shared/Makefile.in:  corrected dates.
* gm2/gm2-libs-iso/MemStream.mod:  assign res to opened (bugfix).
* gm2/gm2-libs/CmdArgs.def:  corrected dates.
* gm2/gm2-libs/CmdArgs.mod:  corrected dates.
* libgm2/libpim/Makefile.am:  added SCmdArgs.def to be installed.
* libgm2/libpim/Makefile.am:  added SCmdArgs.mod to be built and
  installed.

* gm2/gm2-compiler/M2GenGCC.mod:  modified debugging hooks.
* gm2/gm2-compiler/M2Quads.mod:  (BuildConvert) allow record types
  to be converted as they might fit into a generic type.
* gm2/gm2-gcc/m2convert.c:  (same_size_types)  New function.
  (converting_ISO_generic) only convert using short hand generic
  types if they are the correct size.  (const_to_ISO_aggregate_type)
  New function.
* gm2/gm2-lang.c:  (convert) simplified.

* gm2/README:  corrected README to reflect prefered method of obtaining
  tar.gz file.  Also improved the text.  Removed the build instructions
  and replaced it with a reference to the documentation.
* gm2/examples/pge/deviceIf.mod:  added DebugTrace feature.
* gm2/examples/pge/twoDsim.mod:  added DebugTrace feature.
* gm2/examples/pge/world.mod:  useGroff by default.
* gm2/gm2-compiler/M2Base.mod:  fixed bug to allow BYTE to be parameter
  compatible with any BYTE sized type (including packed RECORD).
