Intrinsics

The C intrinsics of Clang 23.1.2 that compile to VPSHUFD, 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.

Clang's comment names VPSHUFB, the byte shuffle; this intrinsic shuffles doublewords by an immediate, and Clang emits VPSHUFD.

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.
