# Intermediate code generation

- To access named parameters and local variables inside a procedure, IR should
  be able to reference them. During the generation the needed information (e.g.
  offsets or registers) can be extracted from the symbol table and saved in the
  operands.

# ELF generation

- Don't ignore relocations where the symbol is not defined in the symbol table.
  Report an error about an undefined symbol.

# Name analysis

- Format error messages.
- Return non-zero error code on errors.

# Register allocation

- Each temporary variales gets a tn register where n is the variable index. If
  there more variables the allocation will fail with out of bounds runtime
  error. Implement spill over.

# Other

- Type analysis.
