congenial-elucidator's Issues

`not` instruction is broken

Write target code to file

Add block numbers to variables

For #5

Strange behaviour in loops

MIPS program does not terminate properly

Local offsets are wrong for the first function in a program

Dynamically determine stack frame size

Add function definitions and function calls

Write a README

Explain the project and document the usage.
Don't forget to include changes to the original grammar and language specs (function definitions before everything, no floats etc.).

Return value of main is ignored

Block numbers messed up when no functions are defined

Add floating point support

Adding float support would require too much rework. I don't think I'll be able to deail with that in time.

Logical not operation is broken

Emits non-register operands for register operations

Implement return statement

Grammar is not LALR(1)
