cminor is a c-like language which supports most of the C language features except for pointer, and adopts a slight different declaration syntax.
Here is the specification of cminor: http://www3.nd.edu/~dthain/courses/cse40243/fall2015/cminor.html

To clean up the directory, run:
$ make clean

To generate cminor:
$ make

Having a cminor executable, you can do the following actions:
Print a a cminor program beautifully:
$ ./cminor -print good1.cminor
or 
$ ./cminor -parse good1.cminor

Resolve variables in a cminor program:
$ ./cminor -resolve good1.cminor

Type check of a cminor program:
$ ./cminor -typecheck good1.cminor

Generate the assembly code for a cminor program:
$ ./cminor -codegen good1.cminor

Test Cases:
`parser_test` includes 10 good test cases and 10 bad test cases.
`typecheck_test` includes 10 good test cases and 10 bad test cases.
`codegen_test` includes 20 good test cases.
To run the test cases under these three test dirs, you need to first generate cminor in the current dir. 
The cminor under each test dir is a symlink pointing to the cminor in the current dir.
