+// These Sel patterns support the generation of conditional move
+// pseudo instructions.
+//
+// The nomenclature uses the components making up the pseudo and may
+// be a bit counter intuitive when compared with the end result we seek.
+// For example using a bqez in the example directly below results in the
+// conditional move being done if the tested register is not zero.
+// I considered in easier to check by keeping the pseudo consistent with
+// it's components but it could have been done differently.
+//
+// The simplest case is when can test and operand directly and do the
+// conditional move based on a simple mips16 conditional
+// branch instruction.
+// for example:
+// if $op == beqz or bnez:
+//
+// $op1 $rt, .+4
+// move $rd, $rs
+//
+// if $op == beqz, then if $rt != 0, then the conditional assignment
+// $rd = $rs is done.
+
+// if $op == bnez, then if $rt == 0, then the conditional assignment
+// $rd = $rs is done.
+//
+// So this pseudo class only has one operand, i.e. op
