* How-to

    1. `make`

----------------------------

## Usage

* Command line parameters for jcc


    `jcc [options]  [input_file2] [input_file3] ...`


    Options:

    * `--dump-html `


        Output the token stream and AST to a HTML file to view

    * `--lex`


        Do the tokenize(lexical analysis) stage only

    * `--parse`


        Do the parse(syntax analysis) stage only

    * `--llvm`


        Do the compile stage only. (Generate the llvm assembly file)

    * `-S`


        Do the compile stage only. (Generate the target assembly file)

    * `-c`


        Do the assemble stage only. (Generate the object file)

    * `-o `


        Specifiy the output filename

	* `-fno-builtin`


		Don't include the standard library automatically. Mainly used to compile standard library itself.

* Built-in tests


    You can just run `make test`, it will compile the test cases in `tests` directory using option `jcc --dump-html tests/xxx.html --llvm -o tests/xxx.ll tests/xxx.jas` and then run `clang` to compile and link the `.ll` file against jascal libs' implementations (such as `lib/io.impl.ll`)


    For eash test case, it will generate an `xxx` file which is the executable binary file of the source file, and an `xxx.html` file which could be opened in browser to see the token stream and the AST of the source file

	Additionally, if there is any test data for a test case (named `tests/xxx-testx.in` and `tests/xxx-testx.out`), the tester will automatically run the executable file and feed the `.in` file to it, then get the output and compare it with `.out` file. There will be a time limit which is set to 2 seconds. The comparison will ignore blank line. A `[TEST] xxx.in -> xxx ...pass` will be printed if the output match the `.out` file.
