GM2 Release 0.42

GM2 Release 0.41

native sparc port passes make gm2.paranoid and make check-gm2
native i386 port passes make gm2.paranoid and make check-gm2
fixed bug in M2GenGCC.mod, coerced constant set parameter values to correct set type.
fixed bug in M2GenGCC.mod when assigning constant to an ISO WORD

GM2 release 0.40
brought GM2 up to date with gcc-3.3.1
many, many bug fixes and no patch is now required in the garbage collection of gcc-3.3.1
major recoding of M2Code and the order that quadruples are coded into GCC trees. This in turn fixes a very serious nested procedure bug.
many internal rewrites resulting in cleaner code.
fixed a number of uninitialized variables using valgrind.
builds under Redhat 9.0 and Suse
added the LONGCARD data type.
fixed subrange declarations so that they can be prefixed by a qualident.
fixed variant record for ISO syntax, implemented ISO BITSETs.
fixed importing of an enumerated element.
enabled SIZE to be invoked from constant expressions.
LENGTH is now mapped onto M2RTS.Length if the parameter is not a constant at compile time.

compiler is now fully PIM compliant. Work is underway on implementing the ISO Modula-2 semantics (and are invoked by the language dialect switch -Wiso)
standard procedures can be called inside constant expressions.
finished all PIM standard procedures
fixed bugs when exporting derived types based on enumerated types
introduced examples/pthread
fixed bug in constant set arithmetic
fixed automatic export of unqualified identifiers from a DEFINITION MODULE FOR "C"
gm2/examples/vga.def generated by h2def
better support for gdb from ARRAY OF CHAR
some portability features of p2c fixed, so that p2c builds cleanly under Apple Darwin
introduced a tool, h2def, to aid production of DEFINITION MODULE FOR "C" modules from C header files.
applied many optimisation fixes.
fixed source code line numbering in debugging information.
added MathLib0 module, added svga example.
fixed many floating point bugs.
added access to thirty one gcc built-in functions.

GM2 Release 0.33

implemented large sets.
implemented ISO compliant sets.
when gm2 is invoked with -gstabs a patched gdb will display set contents. This also works well with SET OF CHAR.
definition modules no longer have to explicitly export identifiers.
gdb has been patched to understand gm2 large sets, down it here: gdb-5.2.1+gm2.tar.gz.

GM2 Release 0.32

the Makefile.in’s have been modified to understand VPATH. Thus adhering to the convention of building outside the source tree. Particularly useful when building gm2 for different architectures as only one source tree is required.
gm2 can be built as a native or as a cross compiler (and has been cross targeted to the strongarm).
the sources to gm2 should now be grafted onto the gcc- source tree.

it now understands DEFINITION MODULE FOR "C" and will handle C varargs. Printf can now be used in modula-2 programs.
-Wmakeall is now available and allows a user to request all defendant modules be compiled and linked. Internally gm2 builds a makefile and runs make on it.
it now uses a machine generated parser and a flex built lexical analyser.
the C preprocessor can be invoked and it processes both definition and implementation modules.
error reporting understands preprocessed Modula-2 source.
the bootstrap tool p2c has been tidied up and in turn this has allowed the compiler to be implemented using opaque types.
the new string module String is used throughout. String lengths are now dynamic.
improved the build procedure. (Removed recursive makes and symbolic links)
