Constructor & Destructor Documentation

gtpin::IargSimdMask::IargSimdMask	(	bool	ignoreCeMask,
		uint32_t	execMask,
		const GtPredicate &	predicate = GtPredicate()
	)		[inline]

Construct HLI argument that evaluates the mask of effective SIMD channels at the instrumentation point ceMask = ignoreCeMask ? 0xffffffff : ChannelEnableReg() simdMask = ceMask & DispatchMaskReg() & execMask & Mask(predicate)

Parameters:

[in]	ignoreCeMask	Flag that indicates whether the mask in ChannelEnableReg should be applied (false) or ignored (true) in the computation of effective SIMD channels
[in]	execMask	Execution mask to be used in the computation of effective SIMD channels. Normally, this mask is produced by the GtExecMask::Bits() function.
[in]	predicate	Predicate to be used in the computation. Invalid predicate is ignored

)

const [inline]

Create IGtIarg object that assigns this argument value to the formal parameter of type PRMT.

Note:

The array of GRF registers is passed by pointer

Parameters:

PRMT	Type of the formal parameter of the function

Returns:

New IGtIarg object of type GtIargType::SIMD_MASK

Precondition:

PRMT is a pointer type
