[kaffe] I'm going on porting in the XScale(PXA 255) board. But, I have error message.

Hi,

It seems to me that your compiler & binutils do not like each other much.

I'd recommend configuring Kaffe to use the interpreter and jthreads for
your platform, first, as that should be easier to debug. Make sure that
you read FAQ.crosscompilation. Using libffi would also be an option,
should you encounter trouble with the sysdepCallMethod later.

Make sure that you use the cross compiler toolchain from the board vendor.

that patch looks interesting, why was it necessary?

Is there a specific reason why you're passing __XSCALE__ to the compiler?

There is no explicit stmfd instruction anywhere in Kaffe's assembler
code, afaict (might be diifferent for 1.1.4, though, I have not checked.
You can run grep yourself to see if I am right with yout checkout ;).

I believe that your compiler outputs instructions that your assembler
does not have. Check with your toolchain or board vendor to see how to
set it up properly. I'd recommend first cross-compiling and runnign the
GNU hello package, to make sure that your cross-compilation setup really
works as it should.
