</p> <p> For instance, some architectures provide a "fused multiply and add" (FMA) instruction that computes <code>x*y + z</code> without rounding the intermediate result <code>x*y</code>. These examples show when a Go implementation can use that instruction: </p> <pre> // FMA allowed for computing r, because x*y is not explicitly rounded: r = x*y + z r = z; r += x*y

Instead, the compiler operates on a kind of semi-abstract instruction set, and instruction selection occurs partly after code generation. The assembler works on the semi-abstract form, so when you see an instruction like <code>MOV</code> what the toolchain actually generates for that operation might not be a move instruction at all, perhaps a clear or load. Or it might correspond exactly to the machine instruction with that name.
