| #### Note: this error code is no longer emitted by the compiler. |
| |
| Cannot convert inline assembly operand to a single LLVM value. |
| |
| Erroneous code example: |
| |
| ```ignore (no longer emitted) |
| #![feature(llvm_asm)] |
| |
| fn main() { |
| unsafe { |
| llvm_asm!("" :: "r"("")); // error! |
| } |
| } |
| ``` |
| |
| This error usually happens when trying to pass in a value to an input inline |
| assembly operand that is actually a pair of values. In particular, this can |
| happen when trying to pass in a slice, for instance a `&str`. In Rust, these |
| values are represented internally as a pair of values, the pointer and its |
| length. When passed as an input operand, this pair of values can not be |
| coerced into a register and thus we must fail with an error. |
