FAMIN

Multi-vector floating-point absolute minimum

Determine the minimum absolute value from floating-point elements of the two or four second source vectors and the corresponding floating-point elements of the two or four first source vectors and destructively place the results in the corresponding elements of the two or four first source vectors.

The behavior is as follows:

• When FPCR.DN is 0, if either element is a NaN, the result is a quiet NaN.
• When FPCR.DN is 1, if either element is a NaN, the result is the Default NaN.
• Denormalized inputs and results are never flushed to zero, as if FPCR.{FZ16, FZ, FIZ} are all 0.
• Denormalized inputs never generate an Input Denormal floating-point exception.

This instruction follows SME2 floating-point numerical behaviors corresponding to instructions that place their results in one or more SVE Z vectors.

This instruction is unpredicated.

It has encodings from 2 classes: Two registers and Four registers

Two registers
(FEAT_FAMINMAX)

if !IsFeatureImplemented(FEAT_SME2) || !IsFeatureImplemented(FEAT_FAMINMAX) then UNDEFINED; if size == '00' then UNDEFINED; constant integer esize = 8 << UInt(size); constant integer dn = UInt(Zdn:'0'); constant integer m = UInt(Zm:'0'); constant integer nreg = 2;

Four registers
(FEAT_FAMINMAX)

if !IsFeatureImplemented(FEAT_SME2) || !IsFeatureImplemented(FEAT_FAMINMAX) then UNDEFINED; if size == '00' then UNDEFINED; constant integer esize = 8 << UInt(size); constant integer dn = UInt(Zdn:'00'); constant integer m = UInt(Zm:'00'); constant integer nreg = 4;
