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.
| Intrinsic | Compiles to |
|---|---|
_mm_shuffle_epi32
__m128i _mm_shuffle_epi32(__m128i a, const int imm) |
|
_mm_mask_shuffle_epi32
__m128i _mm_mask_shuffle_epi32(__m128i W, __mmask8 U, __m128i A, const int I) |
|
_mm_maskz_shuffle_epi32
__m128i _mm_maskz_shuffle_epi32(__mmask8 U, __m128i A, const int I) |
|
_mm256_shuffle_epi32
__m256i _mm256_shuffle_epi32(__m256i a, const int imm) |
Clang's comment names VPSHUFB, the byte shuffle; this intrinsic shuffles doublewords by an immediate, and Clang emits VPSHUFD. |
_mm256_mask_shuffle_epi32
__m256i _mm256_mask_shuffle_epi32(__m256i W, __mmask8 U, __m256i A, const int I) |
|
_mm256_maskz_shuffle_epi32
__m256i _mm256_maskz_shuffle_epi32(__mmask8 U, __m256i A, const int I) |
|
_mm512_shuffle_epi32
__m512i _mm512_shuffle_epi32(__m512i A, const int I) |
|
_mm512_mask_shuffle_epi32
__m512i _mm512_mask_shuffle_epi32(__m512i W, __mmask16 U, __m512i A, const int I) |
|
_mm512_maskz_shuffle_epi32
__m512i _mm512_maskz_shuffle_epi32(__mmask16 U, __m512i A, const int I) |

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.
