On ARM, it turns out that comparisons with NaN can be made to do the right thing with no code penalty, by a more careful selection of condition code values in the subsequent conditional branch. The meaning of the CC bits in the PSR is subtly different when they've been copied from the floating point status register. Suggested patch is 5c-nan-cmp (works on both vfp and emulated arm7500). |
