FMINV

Floating-point minimum recursive reduction to scalar

Floating-point minimum horizontally over all lanes of a vector using a recursive pairwise reduction, and place the result in the SIMD&FP scalar destination register. Inactive elements in the source vector are treated as +Infinity.

When FPCR.AH is 0, the behavior is as follows:

• Negative zero compares less than positive zero.
• When FPCR.DN is 0, if either value is a NaN, the result is a quiet NaN.
• When FPCR.DN is 1, if either value is a NaN, the result is Default NaN.

When FPCR.AH is 1, the behavior is as follows:

• If both values are zeros, regardless of the sign of either zero, the result is the second value.
• If either value is a NaN, regardless of the value of FPCR.DN, the result is the second value.
