Error code E0781
The C-cmse-nonsecure-call
ABI can only be used with function pointers.
Erroneous code example:
#![allow(unused)] #![feature(abi_c_cmse_nonsecure_call)] fn main() { pub extern "C-cmse-nonsecure-call" fn test() {} }
The C-cmse-nonsecure-call
ABI should be used by casting function pointers to
specific addresses.
