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