CBLO (register) Compare unsigned lower than register and branch This instruction compares the unsigned values in two registers, and conditionally branches to a label at a PC-relative offset if the second value is lower than the first. This instruction provides a hint that this is not a subroutine call or return. This instruction does not affect the condition flags. CB<cc> (register) 1 1 1 0 1 0 0 0 1 0 0 0 0 CBLO <Wm>, <Wt>, <label> CBHI <Wt>, <Wm>, <label> Never 1 CBLO <Xm>, <Xt>, <label> CBHI <Xt>, <Xm>, <label> Never <Wm> Is the 32-bit name of the second general-purpose source register, encoded in the "Rm" field. <Wt> Is the 32-bit name of the general-purpose register to be tested, encoded in the "Rt" field. <label> Is the program label to be conditionally branched to. Its offset from the address of this instruction, in the range -1024 to 1020, is encoded as "imm9" times 4. <Xm> Is the 64-bit name of the second general-purpose source register, encoded in the "Rm" field. <Xt> Is the 64-bit name of the general-purpose register to be tested, encoded in the "Rt" field. 2026-03-12 12:23:09 2025-09_rel_asl1
