|
- 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.

- 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.
