INSTRUCTION SET REFERENCE
XORPS—Bit-wise Logical Xor for Single-FP Data
Description
The XORPS instruction returns a bit-wise logical XOR between XMM1 and XMM2/Mem.
Figure 3-101. Operation of the XORPS Instruction
Operation
DEST[127-0] = DEST/m128[127-0] XOR SRC/m128[127-0]
Intel C/C++ Compiler Intrinsic Equivalent
__m128 _mm_xor_ps(__m128 a, __m128 b)
Computes bitwise EXOR (exclusive-or) of the four SP FP values of a and b.
Exceptions
General protection exception if not aligned on 16-byte boundary, regardless of segment.
