# Intermediate code generation

- To access named parameters 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.

# Register allocation

- Each temporary variable 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.
- The allocator puts temporary and local variables into the same registers,
  causing conflicts.

# Language

- Array support.
