ieq (sm4 - asm)

  • Article

Component-wise vector integer equality comparison.

ieq dest[.mask], src0[.swizzle], src1[.swizzle]
Item Description
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
