Shifts values in the given integer vector right by shift bits. Zeroes are shifted in for unsigned vectors, sign bits is shifted in for signed vectors.
The number of bits to shift must be between 0 and e_bits - 1 inclusive, where e_bits is the number of bits in the element type.
The implementation behaves as if the following set of overloads is provided:
Ret

Vec1
|
|---|---|
| int8 | int8 |
| uint8 | uint8 |
| int16 | int16 |
| uint16 | uint16 |
| int32 | int32 |
| uint32 | uint32 |
| int64 | int64 |
| uint64 | uint64 |
The return type is a vector expression.
Parameters[edit]
| a | - | integer vector |
| shift | - | the number of bits to shift |
Return value[edit]
A vector expression evaluating to a >> shift.
Equivalent operation[edit]
r0 = a0 >> shift ... rN = aN >> shift
