--- Comment #9 from Stam Markianos-Wright <stammark at gcc dot gnu.org> --- > Clearly Helium+Linux on Godbolt is a bit confused Yea, I agree -- it still shouldn't be an unintuitive front-end type clash error, though! I've posted another patch: https://gcc.gnu.org/pipermail/gcc-patches/2022-December/607675.html (see there for what the error was --- interestingly it was coming from `__ARM_mve_coerce3` and it didn't directly have anything to do with the float types)
