Looks like a nice improvement @alban.bridonneau! Just had one minor comment on the tests ...



================

+define <vscale x 2 x half> @test_nxv2i16(<vscale x 2 x i16> %a) {
+; CHECK-LABEL: test_nxv2i16
----------------
Hi @alban.bridonneau, I think it's also worth adding tests for the inverse case i.e. bitcast <vscale x 2 x half> -> bitcast <vscale x 2 x i16>. The operations should also be free I think.
