Hi Thomas, Unfortunately, there is no support for running armv7 executables on arm64, though it would technically be possible to implement. I myself would really like to have this sort of thing but I lack the knowledge to have it. Perhaps someone feels adventurous enough to look into implementing support for this sort of thing. For historical reasons, the i386 and amd64 ports of gcc and clang have a largely shared code base and are essentially the same port. So options -m32, -m64 can be used to switch between them. The same is not possible for armv7 and arm64 which are distinct ports with little to no shared backend code. Consider using -target armv7 instead.
