| #### 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. |
