unable to find a register to spill in class

["Nemanja Popov" <nemanja dot popov at micronasnit dot com>]

Hi All,

I'm pretty new in porting and understunding GCC. I am trying to port gcc 
4.02 to the DLX procesor by using dlx port for gcc 2.7.3.

Now I have the following problem:


. -I../../gcc -I../../gcc/. -I../../gcc/../include -I../../gcc/../libcpp/include 
 -DL_muldi3 -c ../../gcc/libgcc2.c -o libgcc/./_muldi3.o
../../gcc/libgcc2.c: In function â__muldi3â:
../../gcc/libgcc2.c:535: error: unable to find a register to spill in class 
GR_REGS
../../gcc/libgcc2.c:535: error: this is the insn:
(insn 6 15 9 0 ../../gcc/libgcc2.c:526 (set (reg/f:SI 82 [ D.1307 ])
       (mem/f/i:SI (reg/f:SI 30 r30) [6 D.1307+0 S4 A32])) 40 
{movsi_general} (nil)
   (expr_list:REG_EQUIV (mem/f/i:SI (reg/f:SI 30 r30) [6 D.1307+0 S4 A32])
       (nil)))
../../gcc/libgcc2.c:535: confused by earlier errors, bailing out


I'm stucked here for almost a week. If you need more data please let me know 
and I'll send them to this list.
I was trying with -da optionn but I'don't understand .greg file format.

Thanks,
Nemanja
