vec_sra
Purpose
Performs an algebraic right shift for each element of a vector.
Syntax
d=vec_sra(a, b)Result and argument types
The following table describes the types of the returned value and the function arguments.
| d | a | b |
|---|---|---|
| vector signed char | vector signed char | vector unsigned char |
| vector unsigned char | vector unsigned char | vector unsigned char |
| vector signed short | vector signed short | vector unsigned short |
| vector unsigned short | vector unsigned short | vector unsigned short |
| vector signed int | vector signed int | vector unsigned int |
| vector unsigned int | vector unsigned int | vector unsigned int |
| vector signed long long | vector signed long long | vector unsigned long long |
| vector unsigned long long | vector unsigned long long | vector unsigned long long |
Result value
Each element of the result vector is the result of algebraically right shifting the corresponding element of a by the number of bits specified by the value of the corresponding element of b, modulo the number of bits in the element. The bits that are shifted out are replaced by copies of the most significant bit of the element of a.
