hi all,
(1) while compiling from the CVS, i've encountered this problem:
config/msp430/libgcc.S: Assembler messages:

make[2]: *** [libgcc/./_cmpdi2.o] Error 1
i'm using the gcc-3.3 branch (of MSPGCC) and gcc-3.2.2 source, but
gcc-3.2 source gives the same error. since i have actually compiled it
successfully once, i am wondering if any CVS commit has produced the
error.
(2) which branch is actually the latest? the only thing i know for sure
is that gcc-3.1 is not being maintained
(3) i am also wondering why createlinks_gcc.py has hardcoded the branch
to gcc-3.0.
(4) the script createlinks_gcc.py actually does not work for me. i have
looked at the source code, understood it and modified it to the essense
of what the original createlinks_gcc.py is purported to achieve. (see
below). logically the error should not be due to my modified version of
createlinks_gcc.py.
thank you,
yw
