Bug ID: 91342 Summary: Incorrect parameter type for AVX512 streaming intrinsics. Product: gcc Version: 9.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: a-yee at u dot northwestern.edu Target Milestone: --- According to Intel's docs, all 4 of the AVX512 streaming instructions take void pointers. void _mm512_stream_ps (void* mem_addr, __m512 a) void _mm512_stream_pd (void* mem_addr, __m512d a) void _mm512_stream_si512 (void* mem_addr, __m512i a) __m512i _mm512_stream_load_si512 (void const* mem_addr) But GCC's implementation takes typed pointers. https://godbolt.org/z/Dkte12
