Results in CR[CRn], where n= BF. 282
cmpi BF, 0, RA, IM Compare (RA) to EXTS(IM), signed.
Results in CR[CRn], where n= BF. 283
cmpl BF, 0, RA, RB Compare (RA) to (RB), unsigned.
Results in CR[CRn], where n= BF. 284
cmpli BF, 0, RA, IM Compare (RA) to (160 || IM), unsigned.
Results in CR[CRn], where n= BF. 285
