I sent a patch to gcc-2.7.2 to add support i960Jx targets (including the
i960RP). I goofed. Find the latest version included below, and also
available at <ftp://ftp.picturel.com/pub/source/i960gcc-gcc-2.7.2.patch>

The spec that calls the assembler did not pass the -AJX flag, like it
should, and does with this patch. Sorry.

----

This patch adds to gcc-2.7.2 support for the i960Jx series targets,
including the i960rp. In practice, the compiler itself is already
able to handle these targets, but the patch adds the -mjx flags
to the driver so that default flags are set correctly for the processor
at hand.

This patch also changes the default processor type to -ka instead of
-mkb. This is necessary to allow a non-numerics libgcc.a to be built
and -mja, -mjd and -mrp would not work without this change.

To apply this patch, cd to gcc-2.7.2 and execute ``patch -p1 < file''
where file is this input file.

	* config/i960/i960.h: Add specification for -Jx types
	* config/i960/t-960bare: include multilib support for Jx types.
