With FP16_OVFL=1 the hardware writes an f16 result that would round to infinity as the largest finite value of that sign, unless a source operand is infinite. v_div_fixup_f16 keeps the infinity it writes for a zero denominator or an infinite numerator. Measured on RDNA2 (gfx1036) at IEEE=0 and IEEE=1 with f16 denormals kept and flushed. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> |
