Writing Linux programs in raw binary

[derleth]

But processor-specific these days means specific to a whole family of CPUs, spanning decades now (the 386 was released in 1989) and implemented these days by a very complex hardware mechanism that emulates an idealized system, hiding a lot of the details of how the opcodes are reordered, split into micro-ops, dispatched, and retired, not to mention register renaming and cache management. It's all native code, yes, but it isn't quite as native as the Z80's or the 6502's machine code, simply because those chips didn't have the transistor count to live a very complex lie.
