// 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.
|
||||
//
