Description
--------------------------------------------------------------------------
This is my simple compiler. It performs lexical, grammar analysis, and then 
emit the assembly code, dump the code into plain text. At last, the 
assembly code is sended to assembly compiler "as" to generate object file.
The linker 'ld' link obj file to executable file. 
Basically, I finish the front-end and code-generation work. The executable 
file generation is handled by system software. Because to output the 
instruction to binary form and arrange the output file according to ELF 
ABI rule is a trivial thing. I omitted that. :-(


Language rule
--------------------------------------------------------------------------
The language can use/define variable, use conditional statement, define 
and call function, even though it has a lot of contraints.

To simplify the problem, I make a lots of contraints and assumptions. You
may think it's unreasonable and weird. Well, it's just a piece of work 
for fun. :-)

In fold example/, there are several simple samples to show the language's 
grammar and function.




Other things
--------------------------------------------------------------------------
I previously planed to build a complete, independent compiler. But as  the
process going on, I was busy with other affairs and found a lot of trivial
thing to build the compiler by oneself. Finally it was born like this. 

I am keen on the compiler techniques, operating system knowledge and other
low level computer science related things. Glad to communicate with peers
in these fields.
