--- Comment #2 from Robin Dapp <rdapp at gcc dot gnu.org> --- Another idea is to have a separate FoF pattern with a flag that specifies that it wants to set the VL. Then, in the vsetvl pass, where things actually go wrong by inserting the clobbering VLs, we could have a final round of emitting a csrr if indicated by such a flag. I'm going to experiment a bit.
