vec_sldw
Purpose
Shift Left Double by Word Immediate
Returns a vector by concatenating a and b, and then left-shifting the result vector by multiples of 4 bytes. c specifies the offset for the shifting operation.
Syntax
d=vec_sldw(a, b, c)Result and argument types
The following table describes the types of the returned value and the function arguments.
| d | a | b | c |

| vector float | vector float | vector float | |
| vector double | vector double | vector double |
Result value
After left-shifting the concatenated a and b by multiples of 4 bytes specified by c, the function takes the four leftmost 4-byte values and forms the result vector.
