Adding to kou's comment, the code you pasted are specific to the arrow compute functions. Currently no compute functions have a SSE kernel implementation so there's no need yet to check SSE in runtime. There are other places where arrow uses SSE such as in handling csv and json files. `ARROW_HAVE_SSE4_2` is used instead of `ARROW_HAVE_RUNTIME_SSE4_2` because they don't require runtime dispatching, unlike compute functions. -- This is an automated message from the Apache Git Service.
