I'l change the cast and investigate other vector types. I haven't tested with scalable vectors. I didn't see a generic vector type I could use and I just noticed in lldb the clang vectors had a FixedVector type so went with that. https://github.com/llvm/llvm-project/pull/84526 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
