VMOVHLPS missing from instruction tables?

Post by TiborGY » 2025-05-19, 14:52:54

AVX seems to have a 3 operand version of MOVHLPS. Maybe I am missing something, but I cannot find it in the instruction tables for any of the CPUs.

The 2-operand versions of vector instructions and the 3-operand versions with V prefix have the same figures. They are not listed separately for reasons of space.
