vec_pack
Purpose
Packs information from each element of two vectors into the result vector.
Syntax
d=vec_pack(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 short | vector bool short |
| vector signed char | vector signed short | vector signed short |
| vector unsigned char | vector unsigned short | vector unsigned short |
| vector bool short | vector bool int | vector bool int |
| vector signed short | vector signed int | vector signed int |
| vector unsigned short | vector unsigned int | vector unsigned int |
| vector float | vector double | vector double |
Note: The following types are valid when the -mcpu option is set to target POWER8 processors, or higher.
| d | a | b |
|---|---|---|
| vector bool int | vector bool long long | vector bool long long |
| vector signed int | vector signed long long | vector signed long long |
| vector unsigned int | vector unsigned long long | vector unsigned long long |
Result value
The value of each element of
the result vector is taken from the low-order half of the corresponding
element of the result of concatenating a and b.
