Thank you very much!
a dumb question...
how do I apply these patches (roughly)?

The patch is too big for this mailing list. I've uploaded a copy to:
http://sourceforge.net/projects/mspgcc4/files/Patches/msp430-r4.20100210-chipcat.patch
It's also available within the SRPM.

Yes, it is probably due to hardware multiply. I can replicate the
problem on an older install, but it's fixed with one built from
the SRPMs I posted which include a patch for hardware multiply. I
haven't had time to integrate that with the mainline developers; a
copy is attached.

I just tried to use strotl() on the msp430f5437. It
failed and I tracked the problem down to a problem with
multiply. Check this out:
register unsigned long int tmp1 = i;
unsigned long int tmp2 = i;
long int tmp3 = i;
int tmp4 = i;
printf("i %lx tmp1 %lx tmp2 %lx tmp3 %lx tmp4
%x\n",i,tmp1,tmp2,tmp3,tmp4);
tmp1 = tmp1 * base;
tmp2 = tmp2 * base;
tmp3 = tmp3 * base;
tmp4 = tmp4 * base;
printf("i %lx tmp1 %lx tmp2 %lx tmp3 %lx tmp4
%x\n",i,tmp1,tmp2,tmp3,tmp4);
i 0 tmp1 0 tmp2 0 tmp3 0 tmp4 0
i 0 tmp1 3fff3fff tmp2 3fff3fff tmp3 3fff3fff tmp4 0
Any advice how to proceed with debugging this? Is this a
problem with usage of hardwarde multiplier?
