# ishr (sm5 - asm)

Arithmetic shift right (sign extending).

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

Item | Description |
---|---|

[in] Contains the results of the shift. | |

[in] The number of bits to shift. | |

[in] The 32-bit values to shift. |

## Remarks

This instruction performs a component-wise arithmetic shift of each 32-bit value in *src0*
right by an unsigned integer bit count provided by the LSB 5
bits (0-31 range) in *src1*, replicating the
value of bit 31. The 32-bit per component result is placed in
*dest*.

This instruction applies to the following shader stages:

Vertex | Hull | Domain | Geometry | Pixel | Compute |
---|---|---|---|---|---|

X | X | X | X | X | X |
