FMINNMQV

Floating-point minimum number recursive reduction of quadword vector segments

This instruction calculates a floating-point minimum number of the same element numbers from each 128-bit source vector segment using a recursive pairwise reduction, and places each result into the corresponding element number of the 128-bit SIMD&FP destination register. Inactive elements in the source vector are treated as the default NaN.

Regardless of the value of FPCR.AH, the behavior is as follows:

• Negative zero compares less than positive zero.
• If one value is numeric and the other is a quiet NaN, the result is the numeric value.
• When FPCR.DN is 0, if either value is a signaling NaN or if both values are NaNs, the result is a quiet NaN.
• When FPCR.DN is 1, if either value is a signaling NaN or if both values are NaNs, the result is Default NaN.
