| /* Add any extra modes needed to represent the condition code. |
| |
| 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). */ |
