ishl (sm5 - asm)

Shift left.

ishl dest[.mask], src0[.swizzle], src1[.swizzle]

 

ItemDescription

dest

[in] Contains the results of the shift.

src0

[in] The number of bits to shift.

src1

[in] The 32-bit values to shift.

 

Remarks

This instruction performs a component-wise shift of each 32-bit value in src0 left by an unsigned integer bit count provided by the LSB 5 bits (0-31 range) in src1, inserting 0. The 32-bit per component results are placed in dest.

This instruction applies to the following shader stages:
