 /// Implement a low-level type suitable for MachineInstr level instruction
 /// selection.
 ///
-/// This provides the CodeGen aspects of LowLevelType, such as Type conversion.
+/// For a type attached to a MachineInstr, we only care about 2 details: total
+/// size and the number of vector lanes (if any). Accordingly, there are 4
+/// possible valid type-kinds:
+///
+///    * `sN` for scalars and aggregates
+///    * `<N x sM>` for vectors, which must have at least 2 elements.
+///    * `pN` for pointers
+///
+/// Other information required for correct selection is expected to be carried
+/// by the opcode, or non-type flags. For example the distinction between G_ADD
+/// and G_FADD for int/float or fast-math flags.
