vec_cmpeq
Purpose
Returns a vector containing the results of comparing each set of corresponding elements of the given vectors for equality.
This function emulates the operation on long long vectors.
Syntax
d=vec_cmpeq(a, b)Result and argument types
The following tables describe the types of the returned value and the function arguments.
| d | a | b |
|---|---|---|
| vector bool char | vector bool char | vector bool char |
| vector signed char | vector signed char | |
| vector unsigned char | vector unsigned char | |
| vector bool short | vector bool short | vector bool short |
| vector signed short | vector signed short | |
| vector unsigned short | vector unsigned short | |
| vector bool int | vector bool int | vector bool int |
| vector signed int | vector signed int | |
| vector unsigned int | vector unsigned int | |
| vector float | vector float | |
| vector bool long long | vector bool long long | vector bool long long |
| vector double | vector double |
When you call this built-in function, the following types are valid only when -qarch is set to target POWER8® processors.
| d | a | b |
|---|---|---|
| vector bool long long | vector signed long long | vector signed long long |
| vector unsigned long long | vector unsigned long long |
Result value
For each element of the result, the value of each bit is 1 if the corresponding elements of a and b are equal. Otherwise, the value of each bit is 0.
