Vectors of i1 are supported on IRlevel and below down to many SIMD ISAs, such as AVX512, ARM SVE (fixedvector length) and the VE target (NEC SX-Aurora TSUBASA).The RFC on cfe-dev: https://lists.llvm.org/pipermail/cfe-dev/2020-May/065434.htmlReviewed By: erichkeaneDifferential Revision: https://reviews.llvm.org/D88905 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/vector-size-conditional.cpp Wed, 16 Mar 2022 10:10:11 +0000 Simon Moll <simon.moll@emea.nec.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/vector-size-conditional.cpp#fc8d3766 [ExtVectorType] Support conditional select operator for C++.This patch implements the conditional select operator forext_vector_types in C++. It does so by using the same semantics as forC.D71463 added support for the conditional select operator for VectorTypein C++. Unfortunately the semantics between ext_vector_type in C aredifferent to VectorType in C++. Select for ext_vector_type is based onthe MSB of the condition vector, whereas for VectorType it is `!= 0`.This unfortunately means that the behavior is inconsistent betweenExtVectorType and VectorType, but I think using the C semantics forExtVectorType in C++ as well should be less surprising for users.Reviewed By: erichkeane, aaron.ballmanDifferential Revision: https://reviews.llvm.org/D98055 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/vector-size-conditional.cpp Tue, 09 Mar 2021 12:22:20 +0000 Florian Hahn <flo@fhahn.com>
