The equivalent I have is DO WHILE,TROT,R14,R2,B'0001' -- the last operand could be O, or it could be an UNTIL loop with NO (and any other typical condition). But we allow bare condition-code masks, too, especially for cases where the mnemonics aren't really mnemonic.
The SPMs we use also allow direct specification of the CC if you prefer numbers, etc. It will generate 15-x where 'x' is whatever you've specified.
I don't understand the use of WHILE in your example. In most languages, WHILE tests the condition *before* the first loop iteration and UNTIL tests after.
