; In all positive tests, we should reassociate binops
|
|
; to allow more factoring folds.
|
|
|
|
; There are 5 associative integer binops *
|
|
; 13 integer binops *
|
|
; 4 operand commutes =
|
|
; 260 potential variations of this fold
|
|
; for integer binops. There are another 40 for FP.
|
|
; Mix the commutation options to provide coverage using less tests.
