We have a CCNZ mode which is used for implicit comparisons with zero when arithmetic instructions set the condition code. Only the N and Z flags are valid in this mode, which means that only the =,!= and <,>= operators can be used in conjunction with it. We also have a CCCmode which is used by the arithmetic instructions when they explicitly set the C flag (unsigned overflow) and by the bit-test instruction. Only the =,!= and unsigned <,>= operators can be used in conjunction with it. We also have a CCVmode which is used by the arithmetic instructions when they explicitly set the V flag (signed overflow). Only the =,!= operators can be used in conjunction with it. We also have two modes to indicate that the condition code is set by the the floating-point unit. One for comparisons which generate an exception if the result is unordered (CCFPEmode) and one for comparisons which never generate such an exception (CCFPmode). */ CC_MODE (CCNZ); CC_MODE (CCC); CC_MODE (CCV); CC_MODE (CCFP); CC_MODE (CCFPE);
