Shifts values in the given integer vector left by shift bits. Zero bits are shifted in.
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
