9.14.4 i860 Opcodes

All of the Intel i860XR and i860XP machine instructions are supported. Please see either i860 Microprocessor Programmer's Reference Manual or i860 Microprocessor Architecture for more information. Other instruction support (pseudo-instructions)

For compatibility with some other i860 assemblers, a number of pseudo-instructions are supported. While these are supported, they are a very undesirable feature that should be avoided – in particular, when they result in an expansion to multiple actual i860 instructions. Below are the pseudo-instructions that result in expansions.
