Hi Steve,
Can you explain what differences you find? The CVS patches for mspgcc
for 3.2.3 include some changes to 3.2.3 to make it compile with GCC >=
4.0.0. Are those the differences you are seeing?
If I copy the files from mspgcc/gcc/gcc-3.3 ... into a gcc-3.2.3
directory and compare the differences in
diff -rNU 5 gcc-3.2.3-orig/config.sub gcc-3.2.3/config.sub

The differences in config.sub are not needed as it has (somehow) the
line required for msp430, using the orignal file from gcc-3.2.3 compiles
for the msp430 no problem.

The differences in gcc/config.gcc are a few, but the only line that is
needed is the msp430-*.*) ;;
Interestingly there are two enteries in the case statement for
msp430-*-* (and avr-*-*) and only one is needed.
The changes to make gcc-3.2.3 compile with gcc-4.x don't seem to be
there, this is the changes to include/obstack.h I assume, I was thinking
of putting this file onto the CVS server? which is where I started to
wonder about forking another file into the mspgcc from gcc-3.2.3.
I noticed you have started updating the patches for GCC 3.3. I think
this is pointless. We never obtained good results with 3.3, which is why
we stopped updating it for new devices.
I would agree, I had the patch and assumes I would have to do similar to
gcc-4.0.2 when I got a bit closer, so I fixed it and put it in. I would
agree it produces larger code than 3.2.3. gcc-3.3 has the C++ changes if
anyone wants them, although I have the c++ changes in gcc-3.2.3 also.
