<pre>The documentation of `llvm.bswap` in the LangRef:
<a href="https://llvm.org/docs/LangRef.html#llvm-bswap-intrinsics">https://llvm.org/docs/LangRef.html#llvm-bswap-intrinsics</a>
Seems to convey that it only works on integers:
<span class="quote">> You can use bswap on any integer type that is an even number of bytes (i.e. BitWidth % 16 == 0).</span >
But it also works on vectors as rkruppe mentions here:
