Guy Harris (talk | contribs) →Control flow operations: A skip is more like a forward conditional branch with a fixed offset; for predication I tend to think of the predicate as being part of the instruction itself, rather than the previous instruction. They can skip more than one instruction (the IBM 704 and successors had a "Compare Accumulator and Storage" instruction that skipped either 0, 1, or 2 instructions based on whether AC < M, AC = M, or AC > M). |
Guy Harris (talk | contribs) →Instruction types: That bit about the vector facility and 8087 instructions as coprocessor instructions should be indented and state that it's referring to coprocessor instructions, to make it clearer why it's there. They're not "early" examples; PDP-11 floating-point processor instructions date back before either fo them, for example. |
