Show HN: Compile for Arm at native speeds in an emulated system (opens in new tab)

re: x86 make and shell, it probably won’t work well here because once a process tree goes to x86 land, qemu cannot see it and it can’t “natively” run an arm binary.

Essentially we can only hook execve when emulating - when we run a native binary we no longer have any insight into any execve call it may make. (Though with some additional work I suppose one could also use LD_PRELOAD to hook execve)

This is why binfmt_misc and registering the interpreter with the kernel would be superior, if not for kernel level access requirement
