Compares src2 and src1 values and sets AC register condition code according
Description:
to comparison results. When logical AND of condition code and mask part of
opcode is not zero, the processor branches to instruction specified with targ;
otherwise, the processor goes to next instruction.
targ can be no farther than -2
the Intel i960 processor assembler, targ must be a label which specifies target
instruction's IP.
Functions these instructions perform can be duplicated with a
followed by a branch-if instruction, as described in
"COMPARE" (pg.
