Inline asm doesn't complain about invalid clobbers #71362
Description
To reproduce
Try compiling the following program:
#![feature(asm)]
fn main() {
unsafe {
asm!("" : : : "whatever");
}
}Expected result
It should fail with an error
unknown register name ‘whatever’ in ‘asm’
Like how gcc and clang do in inline asm in C.
Actual result
It compiles without an error.
