ne (sm4 - asm)

Component-wise vector floating point not-equal comparison.

ne dest[.mask], [-]src0[_abs][.swizzle], [-]src1[_abs][.swizzle]

 

ItemDescription

dest

[in] The result of the operation.

src0

[in] The components to compare to src1.

src1

[in] The components to compare to src0.

 

Remarks

This instruction performs the float 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.

Denorms are flushed before comparison with original source registers untouched.

+0 equals -0.

Comparison with NaN returns true.
