The OS can impose radically different constraints on the JIT. In Mankato it is impossible to derive an executable region from mmap that is at the same time writable. On MacOS it is possible, but the VM needs a capability conveyed through its Info.plist and baked in when the app bundle is signed.
doesn't PROT_EXEC imply PROT_READ? a region with write|exec would essentially be equivalent to an unprotected one.
Other linuxes for Pi4 May impose different constraints. As I only have these two variants I need your help in dealing with differing constraints on these other platforms.
I don't have a RP 4 board to test the Ubuntu aarch64 (COVID-19 lockdown constraints). Sorry :-(.
