(I have heard the latter refereed to as 'bi-arch'). This is my understanding: multi-arch is a generalized form of biarch, the idea being that one gdb binary can debug multiple targets. The most common form of this is a gdb that can debug 32-bit and 64-bit binaries on the same machine, but presumably one could build a gdb that can debug e.g. x86 targets natively, and at the same time an embedded arm target. I don't know if we are quite there yet though. Most of this work involves encapsulating target specific operations into vectors that can be changed at runtime, instead of having link-time bindings of those operations. randolph
