A small oddity encountered was that the arg to the intrinsics may be an lvalue without any sort of implicit cast of any kind. I solved this through the EvaluateVectorOrLValue function, which treats the lvalue as if it was in an rvalue cast, which gets me the desired vector. --- clang/docs/LanguageExtensions.rst | 5 +- clang/docs/ReleaseNotes.rst | 3 + clang/lib/AST/ExprConstant.cpp | 138 +++++++++++++++++++++++++- clang/test/Sema/constant-builtins-2.c | 61 ++++++++++++ 4 files changed, 204 insertions(+), 3 deletions(-) diff --git a/clang/docs/LanguageExtensions.rst b/clang/docs/LanguageExtensions.rst index 3bead159c8f946..3204e950f92429 100644 --- a/clang/docs/LanguageExtensions.rst +++ b/clang/docs/LanguageExtensions.rst @@ -2927,7 +2927,7 @@ Query for this feature with ``__has_builtin(__builtin_dump_struct)`` ``__builtin_shufflevector`` is used to express generic vector permutation/shuffle/swizzle operations.
