ieq (sm4 - asm)

Component-wise vector integer equality comparison.

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

 

ItemDescription

dest

[in] The address of the result of the operation.

src0

[in] The value to compare with src1.

src1

[in] The value to compare with src0.

 

Remarks

This instruction performs the integer comparison (src0 == src1) for each component, and writes the result to dest.

If the comparison is true, then 0xFFFFFFFF is returned for that component. Otherwise 0x0000000 is returned

This instruction applies to the following shader stages:
