| #### Note: this error code is no longer emitted by the compiler. | |
| Malformed inline assembly rejected by LLVM. | |
| Erroneous code example: | |
| ```ignore (no longer emitted) | |
| #![feature(llvm_asm)] | |
| fn main() { | |
| let rax: u64; | |
| unsafe { | |
| llvm_asm!("" :"={rax"(rax)); | |
| println!("Accumulator is: {}", rax); | |
| } | |
| } | |
| ``` | |
| LLVM checks the validity of the constraints and the assembly string passed to | |
| it. This error implies that LLVM seems something wrong with the inline | |
| assembly call. | |
| In particular, it can happen if you forgot the closing bracket of a register | |
| constraint (see issue #51430), like in the previous code example. |
