Hello Richard, David and the GCC Steering Committee,
Firstly thank you for the release of gcc-12.1 and secondly thank you
for taking the time to review the Modula-2 front end and for valuable
review feedback over the years. I hope you have all managed to have a
break after the 12.1 release.
Here for reference are the previous patch emails and reviews

Sure I'll try and group the subsequent email patches into the following
categories:
1. all GCC files which have been patched.
2. the top level /gm2tools contents.
3. the top level /libgm2 contents.
4. the glue code (between Modula-2 and GCC) contained in /gcc/m2/gm2-gcc.
(these have not been reviewed before). These will be posted in
3 sub parts.
5. all the driver code /gcc/m2.
6. /gcc/m2/Make-lang.in
(not been reviewed before)
7. /gcc/doc/gm2.texi
(not been reviewed before)
The full source code is available via:
$ git clone git://gcc.gnu.org/git/gcc.git gcc-git-devel-modula2
$ cd gcc-git-devel-modula2
$ git checkout devel/modula-2
currently it is being merged every 1-3 days or so. One of the
recommendations after the last review was to maintain this branch.
Over the last year the changes include many bug porting fixes, removal
of compiler build warnings, migrating the code base to C++, improving
accuracy/detail of compiler error messages and improving error recovery.
It builds on gnu/linux/amd64, gnu/linux/aarch64, gnu/linux/sparc64,
solaris/sparc64, gnu/linux/i386, gnu/linux/ppc64le, gnu/linux/power7
(and probably others). Also built with profiled lto on amd64 and
aarch64.

and now FreeBSD 13 i586 providing a patch was applied for C++.
[Interestingly csinl, ctanl and friends are missing on FreeBSD 13
which cause all runtime tests to fail].
(Test results posted to gcc-testresults).
On amd64-gnu-linux it builds as a cross compiler for aarch64.

I've built GCC from the master branch enabled c,c++,fortran,go,d
and then built GCC from devel/modula-2 enabled c,c++,fortran,go,d,m2
and no further regressions were seen.
Anyway I suspect this email is long enough for now - feel free to ask
questions, 9 patches posted to the gcc-patches list. Let me know if you
require the patch set and/or new files in a different format,
regards,
Gaius
