# Compiler optimisations!

- [ ] [HARD] Immediate operations for values that support it (up to +/- u16::max for addi and subi respectively) 
  - this requires significant complexity in code generation as we need to traverse down the tree when we come across these operations to prevent additional register allocations.

- [ ] [EASY] Add multiply and divide operations to code generation
- [ ] [MEDIUM] proper prefix/postfix inc/dec implementation. slightly more complex as we need to check for a variable and modify it in place
- [ ] [EASY] Investigate logical and operator not compiling - either a lexer or parser issue.
- [x] [MEDIUM] Get shift operations working correctly.
