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.
Note: This built-in function is valid only when you specify the -qaltivec option
and include the
altivec.h file.Syntax
d=vec_cmpeq(a, b)Result and argument types
The following table describes the types of the returned value and the function arguments.
| d | a | b |
|---|---|---|
| vector bool char | vector bool char | The same type as argument a |
| vector signed char | ||
| vector unsigned char | ||
| vector bool short | vector bool short | |
| vector signed short | ||
| vector unsigned short | ||
| vector bool int | vector bool int | |
| vector signed int | ||
| vector unsigned int | ||
| vector float | ||
| vector bool long long | vector bool long long | |
| vector signed long long | ||
| vector unsigned long long | ||
| vector double |
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.
