Are you by any chance using inline assembler code in your source
file? This is the only explanation I have, since GCC does not
generate "r3" references in it's assembler code.
It would have been a good idea if you had included your source code
so we could see what you are doing...

I see. This is your own assembler code, not something generated from
C source code.

Don't write incorrect assembler code, or use the required header
files (like ppc_asm.tmpl).
And while we are at it: be careful not to try privileged instructions
in user space.
This is your own error, not a problem with ELDK.

Hmm...
I've seen these messages before. They were gone when I compiled using
ppc_8xx-gcc compiler of a different ELDK version.
What version of ELDK are you using? Which gcc version?
Succes,
Theo Gjaltema.

This has nothing to do with ELDK versions, or any other toolchain
issues.

It's a user only problem (using symbolic names like "r3" in inline
assember statements without incuding the proper header files to
resolve thise names).

I had that exact same problem, ESPECIALLY when pulling in a fresh kernel
tree from kernel.org.
Fixed it by defining the CROSS_COMPILE environment variable or modifying
the Makefile's CROSS_COMPILE to the correct file prefix name, in your
case, it is probaly either
# export CROSS_COMPILE=ppc_8xx- (DENK gcc 3.3.3)
or
# export CROSS_COMPILE=powerpc-linux- (GNU gcc)
Check your PATH... make sure its picking up the right version...
# whereis ppc_8xx-gcc
# ppc_8xx-gcc --version
or
# powerpc-linux-gcc --version

Ummm.... the compiler included with the ELDK is GNU gcc, too.

An expert is a person who avoids the small errors while sweeping on
