IR generator does not handle identifiers in expressions #4
Description
Bug Report: IR Generation Does Not Handle Variable References
Description
The parser correctly builds AST nodes for identifiers (AST_VAR), but the IR generation phase does not handle them at all.
As a result, any expression that references a variable is parsed successfully but fails to generate correct IR and LLVM output.
Example Input
let x = 1;
let y = x + 2;
Current Behavior
- AST_VAR nodes are created by the parser
generate_ir_from_ast()ignores AST_VAR- IR generation produces incomplete or incorrect LLVM IR
- No error is reported
Expected Behavior
- Identifiers should be translated into IR by loading their values
- Variable declarations should store computed values
- Using an undefined variable should produce an error
