Constructor & Destructor Documentation

gtpin::GtRegRegion::GtRegRegion	(	const GtReg &	reg,
		const GtStride &	stride = `ScalarStride()`
	)		`[inline]`

Construct an integer register region with the direct addressing mode, specified origin and the striding scheme.

The region gets an unsigned integer type whose size is reg.ElementSize().

Parameters:

[in]	reg	The origin element of the register region
[in]	stride	The striding scheme of the register region

gtpin::GtRegRegion::GtRegRegion	(	const GtReg &	reg,
		const GtStride &	stride,
		GtDataType	dataType
	)		`[inline]`

Construct a register region with the direct addressing mode, specified origin, striding scheme and element type.

Parameters:

[in]	reg	The origin element of the register region
[in]	stride	The striding scheme of the register region
[in]	dataType	The type of the region's data element

gtpin::GtRegRegion::GtRegRegion	(	const GtReg &	reg,
		const GtStride &	stride,
		GtDataType	dataType,
		GtAddrMode	addrMode,
		int32_t	addrImm = `0`
	)		`[inline]`

Construct a register region with the specified addressing mode, origin, striding scheme and element type.

Parameters:

[in]	reg	In the direct addressing mode, the origin element of the register region. In the indirect addressing mode, an ARF register that addresses the origin of the register region in GRF
[in]	stride	The striding scheme of the register region
[in]	dataType	The type of the region's data element
[in]	addrMode	The addresing mode of the register region, either direct or indirect
[in]	addrImm	Address immediate offset - a signed integer, added to subregister of the indirectly addressed GRF register. Ignored in the direct addressing mode.
