	Hello,

	We've just got gcc-2.1 on our Sequent Balance machine, but we're
	having problems installing it. The first is a compilation problem with
	aux-output.c. The other problem is more general and appears when
	the newly built compiler is being used to compile libgcc2. It
	generates code that is objected to by the Dynix assembler.
	GCC 1.40 does not exhibit the same problem.
	Our system is:

	Host:			Sequent Balance
	OS:			DYNIX V3.0.14
	Host compiler:		GCC 1.40
	Host assembler:		Dynix as
	Configuration:		balance-dynix
				Linked `config.h' to `./config/xm-ns32k.h'.
				Linked `tm.h' to `./config/sequent.h'.
				Linked `md' to `./config/ns32k.md'.
				Linked `aux-output.c' to `./config/ns32k.c'.
				Linked `tconfig.h' to `./config/xm-ns32k.h'.

========================== BUG 1 ==========================================
	
	The file aux-output.c (./config/ns32k.c) generates a
	compilation error at line 407. See the diff output below:

407c407
< 	  fprintf (file, "0Dx%08x%08x", u.i[1], u.i[0]);
---
> 	  fprintf (file, "0Dx%08x%08x", u.i[1], u.i[0])l

========================== BUG 2 ==========================================

	The second bug occurs while libgcc2 (or any source file containing
	subroutine calls) is being compiled for _divdi3. The compiler
	seems to use an illegal addressing mode for the "bsr" instruction
	(see the assembler output for divdi3 below). Rather than:

		bsr 0(___negdi2)

	GCC 1.40 and DYNIX cc generate

		bsr ___negdi2
