24 | For the RS/6000, we need separate modes when unsigned (logical) comparisons | |
25 | are being done and we need a separate mode for floating-point. We also | |
26 | use a mode for the case when we are comparing the results of two | |
27 | comparisons, as then only the EQ bit is valid in the register. */ | |
