Description
Code
I tried this code:
#![feature(abi_x86_interrupt)]
extern "x86-interrupt" fn foo() -> ! {
todo!()
}I expected to see this happen: It compiles.
Instead, this happened:
error: invalid signature for `extern "x86-interrupt"` function
--> <source>:3:36
|
3 | extern "x86-interrupt" fn foo() -> ! {
| ^
|
= note: functions with the "custom" ABI cannot have a return type
help: remove the return type
--> <source>:3:36
|
3 | extern "x86-interrupt" fn foo() -> ! {
| ^
