Hi,
I have been trying to cross-compile gcc-4.7.0 for new target (my_cpu) and
getting following error at build time.
My build environment is:
-----------------------
Binutils for Target: binutils-2.21
Target CPU: 8-bit processor
Make Result:

Here is the snip of libgcc2.c file at line no. 549
---------------------------------------------
<snip>
__muldi3 (DWtype u, DWtype v)
{
const DWunion uu = {.ll = u};
const DWunion vv = {.ll = v};
DWunion w = {.ll = __umulsidi3 (uu.s.low, vv.s.low)};
w.s.high += ((UWtype) uu.s.low * (UWtype) vv.s.high
+ (UWtype) uu.s.high * (UWtype) vv.s.low);
return w.ll;

Any pointers to fix this issue are very much appreciated.
The problem is not in the libgcc code.
The problem is in the source of your my-cpu-gcc.
Thus, you have to debug your compiler proper to find out where and
why cc1 crashes.
