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

Shifts values in the given integer vector left by shift bits. Zeroes are shifted in for unsigned vectors, sign bits is shifted in for signed vectors. 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
