template<unsigned N, class E1> Ret<N, _DETAIL_> shift_l( const Vec1<N,E1>& a, unsigned shift );
template<unsigned shift, unsigned N, class E1> Ret<N, _DETAIL_> shift_l( const Vec1<N,E1>& a );

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

a	-	integer vector
shift	-	the number of bits to shift

Return value

A vector expression evaluating to a << shift.

Equivalent operation

r0 = a0 << shift
...
rN = aN << shift
