Bug ID: 78782 Summary: [x86] _mm_loadu_si64 intrinsic missing Product: gcc Version: 6.2.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: thiago at kde dot org Target Milestone: --- See this copy of the Intel manual: https://hjlebbink.github.io/x86doc/html/MOVQ.html (note the typo in the _mm_move_epi64 intrinsic). Clang addition: https://reviews.llvm.org/D21504 However, Microsoft's compiler seems not to have it either. Seems like the functionality can be achieved by way of _mm_loadl_epi64.
