On the Qube2, gcc 2.7.2, option -s, to generate MIPS assembler
corresponding to the input C code, generates invalid assembler
by virtue of generating duplicate labels. The resultant 
assembler will not assemble, of course, due to the duplicate
labels.  The code (linux kernel's printk.c) compiles cleanly
from C to object code.

Q: How do I get valid assembler from gcc on Qube2 ?
(My ultimate goal here is to be able to get listings out
of gas.)

gcc 2.7.2 creates a duplicate label for each function label.  That is no
problem as both always have the same value.  But I assume you're talking

This is exactly the problem. The fact that the values are the same is
causing the assembler interface to GCC to fail. When gcc -S outputs a 
.s assembler file, the GNU as assembler errors out on 'duplicate label'.

Further, using the gcc -Wa,... without using -S, causes the compile to 
fail when the assembler is invoked and gives the same errors.

about a different type of label?  Can you send a piece of small piece of
source code and the assembler code generated from it to demonstrate the
problem?

Anyway, these days gcc 2.7.2 is so old these days it's not even funny.  You
really should upgrade.

I'm happy to upgrade...

What is the recommended level for kernel compiles and where can I find it.
I am required to work on 2.0.34C53_SK using Qube2 for my build platform
so I need compatibility. If I could cross compile on x86 that would be 
cool too.

Thanx much
