Forms

Every encoding of VPMOVM2Q that Intel XED knows, one row per XED instruction form (iform). How to read the notation.

Intrinsics

The C intrinsics of Clang 23.1.2 that compile to VPMOVM2Q, each with the form it compiles to and the Clang options it needs. The forms come from compiling every intrinsic and decoding the result with Intel XED; all intrinsics A–Z explains the method.

CPUID and processors

Each form belongs to an XED ISA set. A form can be used when the processor reports every CPUID bit of one of its ISA set's alternatives.

CPUID requirements and processors of the XED ISA sets above. Alternatives are separated by “or”; processors follow XED’s chip model, which covers AMD processors up to Zen 2.
