It seems that conda provides LLVM 23.1. So our conda related CI jobs are failing:

Since LLVM 23 added
-Wunused-templateto-Wall, some code requires modification. It also exposed an issue inCastImplaboutDateandTimestampdata type. https://releases.llvm.org/23.1.0/tools/clang/docs/ReleaseNotes.htmlI am investigating a tricky issue in
cpp/src/gandiva/llvm_generator_test.cc. Under macOS debug build, LLVM 23 is no longer generating vectorized code, causing theTEST_F(TestLLVMGenerator, TestAdd)test to fail. https://releases.llvm.org/23.1.0/docs/ReleaseNotes.html#changes-to-the-llvm-irGH-51245: [C++][Compute][Gandiva] Add support for LLVM 23.1 (#51266)
