vec_max
Purpose
Returns a vector containing the maximum value from each set of corresponding elements of the given vectors.
Syntax

When you call this built-in function, the following types are valid only when -qarch is set to target POWER8® processors.
| d | a | b |
|---|---|---|
| The same type as argument a | vector signed long long | The same type as argument a |
| vector unsigned long long | ||
| vector bool long long |
Result value
The value of each element of the result is the maximum of the values of the corresponding elements of a and b.
