Line 268: − All functions now have the above u32 at -4, therefore funcptr calls now have to start at the actual funcptr start. However, this doesn't apply to calls done during functions' exit: these directly br to the funcptr_addr without extra validation.+ + +
→Web-applets
blr instructions no longer exist: when funcptrs are called, new functions are now called instead which handles the call. The u32 at funcptr_addr-4 must match 0xe7ffdefe, otherwise it will branch to undefined instruction 0x0000dead. Otherwise, it will jump to the funcptr_addr.

Almost all functions now have the above u32 at -4, therefore funcptr calls now have to start at the actual funcptr start. However, this doesn't apply to calls done during functions' exit: these directly br to the funcptr_addr without extra validation.
The above applies to all NSOs in ExeFs.
