Hi,
Thanks for your reply. It said how to fix it as follows
Here is a trivial patch:
--- gcc-3.2.3/gcc/config/msp430/msp430.c 2007-08-28

dummy += 6;
OUT_INSN (len, "clr\t%B0", operands);
OUT_INSN (len, "clr\t%C0", operands);
OUT_INSN (len, "clr\t%D0", operands);
- if (GET_CODE (operands[0]) == REG)
+ if ((GET_CODE (operands[0]) == REG) && len)
*len -= 3;
if (len)
*len = dummy;
But Where am i supposed to find this msp430.c file. I have searched this
entire directory. But It didn't pop up. Thanks.
Regarsd,
