Well, somehow, my name got picked out of the hat to assist someone with
a problem porting gcc to a Bull DPX/2.

Sadly, I know little about gcc and the person who updated us recently
is away.

Below is the information I have been given, you may respond either
directly to me, to this list, or to the person with the problem, whose
name is Graham Alwood and whose address is 100065.1661@compuserve.com

== Given information starts here==
Below is the .s file produced with xgcc when it was trying to compile
the first object in the libgcc2.a library. This was done using gas.

gcc was configured with:
./configure dpx2 --with-gnu-as --with-gnu-ld

Here is the .s file that was produced:

	.file	"libgcc2.c"
gcc2_compiled.:
___gnu_compiled_c:
.text
	.even
.globl ___muldi3
___muldi3:
	link a6,#0
	moveml #0x3e00,sp@-
	movel a6@(8),d3
	movel a6@(12),d4
	movel a6@(16),d5
	movel a6@(20),d6
	movel d4,d0
#APP
	mulul d6,d1:d0
#NO_APP
	movel d0,a1
	movel d1,a0
	movel a0,d0
	movel a1,d1
	movel d4,d2
	mulsl d5,d2
	mulsl d6,d3
	addl d3,d2
	movel a0,d0
	addl d2,d0
	moveml a6@(-20),#0x7c
	unlk a6
	rts

I have included the output from the compiler from where libgcc1.a
is built to where the errors occur in libgcc2.a.

I hope this is of some help.

Thanks again, Graham Allwood.
