Detailed Description

template<>
struct generic::svec< 4, bool >

Data representation and operations on a vector of 4 boolean values. This is used in predicated vector operations. Specifically the ith value of svec<4,bool> indicates whether the ith lane of a predicated vector operation is enabled or not.

Constructor & Destructor Documentation

generic::svec< 4, bool >::svec

(

)

Default constructor.

Returns

a vector of 4 undefined values.

generic::svec< 4, bool >::svec	(	uint32_t	a,
		uint32_t	b,
		uint32_t	c,
		uint32_t	d
	)

Constructor.

Parameters

[in]

a,b,c,d

boolean values

Note

a,b,c,d must be either 0 or -1

Returns

a vector of 4 mask/booleans: {a,b,c,d}.

generic::svec< 4, bool >::svec

(

uint32_t

a
