That would be a saner runtime check to do but it's a balance as RISU is a fairly specialist tool which kind of assumes people know what they are doing. The current check is on SVE_MAGIC in the header files which does mean a binary compiled on an SVE headered system is now carrying about a much larger register dump even when run without the --test-sve flag. Whether it makes sense to be more flexible is a call I'll leave up to Peter. > > [...] > > Cheers > ---Dave -- Alex Bennée
