[Qemu-devel] [PATCH v2 3/5] target-ppc: use the softfloat min/max functions |
Date: |

Use the new softfloat float32_min() and float32_max() to implement the
vminfp and vmaxfp instructions. As a bonus we can get rid of the call to
the HANDLE_NAN2 macro, as the NaN handling is directly done at the
softfloat level.
