+@c FIXME: This is basically a stub for i860. There is tons more information
+that I will add later (jle@cygnus.com). The assembler is still being
+written. The i860 assembler that existed previously was never finished
+and doesn't even build. Further, its not BFD_ASSEMBLER and it doesn't
+do ELF (it doesn't do anything, but you get the point).

+All of the Intel i860 machine instructions are supported.

+Some opcodes are processed beyond simply emitting a single corresponding
+instruction. For example, @samp{mov} and other instructions with larg
+displacements may be expanded into 2 or 3 instructions (FIXME: add details).
