• "Comprehensive checkers"

These programs check that your assembler can handle valid assembly language programs and produce functionally the same object file as the standard assembler. They contain comprehensive testing cases for each testing subject. Since these programs can not be made into executable object files, you need to use the following commands:
• Use the objcmp and objcmp_detail commands to compare the object code produced by your assembler and that by the standard assembler. Note that these commands are "in-house" tools as opposed to those provided by the system. You can find them in the testing_programs/ directory. The -d option compares the data sections, and the -t option compares the text sections:
% objcmp -d objectfile1.o objectfile2.o
% objcmp -t objectfile1.o objectfile2.o
% objcmp_detail -d objectfile1.o objectfile2.o
% objcmp_detail -t objectfile1.o objectfile2.o
• Use the nm command or the elfdump command with the -s option to display the symbol table in the object file
% nm objectfile.o
% elfdump -s objectfile.o
Use the elfdump command with the -r option to display the relocation information in the object file

% elfdump -r objectfile.o

Even if you do not have a complete assembler to produce an object file, for example, you only have finished pass1(),you can still use the print_passes() function provided in the print.c file to print out the content of the symbol table and the sections.
These programs weigh the majority in judging the correctness of your work

• Simple application

These programs let you try your assembler on interesting applications such as printing out the Fibonacci numbers and sorting an array of random integers using the Bubble Sort algorithm. Since these programs can be made into executable object files, you only need to use the gcc command with the -o option

% gcc -o application application.o

% application

These programs weigh 10% in judging the correctness of your work

• Error programs

These programs check if your assembler can detect and report error assembly language programs.

These programs are the extra credits.
