FMINQV Floating-point minimum recursive reduction of quadword vector segments Floating-point minimum of the same element numbers from each 128-bit source vector segment using a recursive pairwise reduction, placing each result into the corresponding element number of the 128-bit SIMD&FP 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.
