+* New matrix math intrinsics have been added to LLVM
+  (see :ref:`LLVM Language Reference Manual <i_matrixintrinsics>`), together
+  with the LowerMatrixIntrinsics pass. The pass lowers matrix intrinsics
+  to a set of efficient vector instructions. The lowering pass is off

+  invocation of clang.
