Input

The input processed by your compiler will be in a file specified on the command line. You will also receive a value signifying which mode your compiler should be run in. The command to run your compiler will take this form:

scalc <mode> <input_file_path> <output_file_path>

Mode can be one of these four values:

• riscv

• x86

• arm

• interpreter

You should open the file input_file_path and parse it. The input file will be a valid scalc file.
