Invalid LHS Of Assignment

[MahadMuhammad]

• Fixing this issue, help [E0070] invalid left-hand side of assignment #2390 to emit more user friendly error code and error emission similiar to rustc.
• You can view the same on compiler-explorer

I tried code:

#![allow(unused)]
const SOME_CONST: i32 = 12;

fn some_function() {
    SOME_CONST = 15; // error: a constant value cannot be changed!

}

fn main(){
    some_function();
}

---

I expected to see this happen:

• Emit error message, similiar to rustc .i.e.,
  • invalid left-hand side of assignment
• Error message emitted by rustc:

error[E0070]: invalid left-hand side of assignment
 --> <source>:6:16
  |
6 |     SOME_CONST = 15; // error: a constant value cannot be changed!
  |     ---------- ^
  |     |
  |     cannot assign to this expression

error: aborting due to previous error

For more information about this error, try `rustc --explain E0070`.

Instead, this happened:

• COmpiled Successfully.
• This is the output of gccrs:

Compiler returned: 0
