Returns a value accumulated from all the lanes of this vector.
This is an associative cross-lane reduction operation which
applies the specified operation to all the lane elements.

A few reduction operations do not support arbitrary reordering
of their operands, yet are included here because of their
usefulness.

 In the case of FIRST_NONZERO, the reduction returns the value from the lowest-numbered non-zero lane. (As with MAX and MIN, floating point negative zero -0.0 is treated as a value distinct from the default value, positive zero. So a first-nonzero lane reduction might return -0.0 even in the presence of non-zero lane values.) 
 In the case of ADD and MUL, the precise result will reflect the choice of an arbitrary order of operations, which may even vary over time. For further details see the section Operations on floating point vectors.

All other reduction operations are fully commutative and
associative.  The implementation can choose any order of
processing, yet it will always produce the same result.

Params:
op – the operation used to combine lane values
Throws:
UnsupportedOperationException – if this vector does
        not support the requested operation

    public abstract float reduceLanes(VectorOperators.Associative op);

    
Returns a value accumulated from selected lanes of this vector,
controlled by a mask.
This is an associative cross-lane reduction operation which
applies the specified operation to the selected lane elements.

If no elements are selected, an operation-specific identity
value is returned.

 If the operation is ADD or FIRST_NONZERO, then the identity value is positive zero, the default float value. 
 If the operation is MUL, then the identity value is one. 
 If the operation is MAX, then the identity value is Float.NEGATIVE_INFINITY. 
 If the operation is MIN, then the identity value is Float.POSITIVE_INFINITY. 

A few reduction operations do not support arbitrary reordering
of their operands, yet are included here because of their
usefulness.

 In the case of FIRST_NONZERO, the reduction returns the value from the lowest-numbered non-zero lane. (As with MAX and MIN, floating point negative zero -0.0 is treated as a value distinct from the default value, positive zero. So a first-nonzero lane reduction might return -0.0 even in the presence of non-zero lane values.) 
 In the case of ADD and MUL, the precise result will reflect the choice of an arbitrary order of operations, which may even vary over time. For further details see the section Operations on floating point vectors.

All other reduction operations are fully commutative and
associative.  The implementation can choose any order of
processing, yet it will always produce the same result.

op – the operation used to combine lane values
m – the mask controlling lane selection

 For each vector lane, where N is the vector lane index, the lane is loaded from the array element a[f(N)], where f(N) is the index mapping expression offset + indexMap[mapOffset + N]]. 
Params:
species – species of desired vector
a – the array
offset – the offset into the array, may be negative if relative
indexes in the index map compensate to produce a value within the
array bounds
indexMap – the index map
mapOffset – the offset into the index map
Throws:
IndexOutOfBoundsException –  if mapOffset+N < 0 or if mapOffset+N >= indexMap.length, or if f(N)=offset+indexMap[mapOffset+N] is an invalid index into a, for any lane N in the vector

Loads a vector from a byte buffer starting at an offset into the byte buffer and using a mask. Lanes where the mask is unset are filled with the default value of float (positive zero). Bytes are composed into primitive lane elements according to the specified byte order. The vector is arranged into lanes according to memory ordering.

FloatBuffer eb = bb.duplicate()
    .position(offset)
    .order(bo).asFloatBuffer();
float[] ar = new float[species.length()];
for (int n = 0; n < ar.length; n++) {

 This operation is likely to be more efficient if the specified byte order is the same as
