Re: GNU cc for HCX-9 and other GNU compiler stuff (M2)

There is a group (I think in Buffalo, NY) porting gcc to the Tahoe.
Keith Bostic (bostic@okeeffe.berkeley.edu) is in touch with this work
and could tell you more.


Gcc is intended to have different front end parsers. It is currently
being used to compile both c and c++, using separate front ends.
Some further work remains to make it possible to build either a gcc
or a g++ (c++ compiler) in the same source directory, but the compiler
is definitely moving in this direction.


If I was to write a "gmm" (GNU Modula-2), I'd build an M2 parser in
place of the existing "c-parse.y" module, make whatever changes
throughout the rest of the code I needed (e.g. new types of scopes or
symbol table info; new operators; etc), and get it running reliably.
By then, if RMS has rearranged C and C++ to be buildable from the same
directory, I'd restructure my sources into his format and send 'em in
to him; otherwise would send in my language-independent changes (e.g.
back end changes) for merging, and track his releases for a few months
until the restructuring is done. (That seems to be what g++ is doing.)
