I want to develop a C compiler.

You know, GCC is very big, It is hard to read its code.

TCC is very good, but no book talks about it, it is hard to understand it.

LCC also opens source, and there is a book talk about it,(A Retargetable C Compiler: Design and Implementation) , but it needs $55.99 in amazon.com.

I can not find the book in my city, maybe i must buy it in amazon.com.

but i want to know how is LCC.

I want to know how does a compiler work.
and improve my assemble language.

Would you look at the Linux source to figure out how an OS works?

Would that teach you how an OS could work?

Same for compilers. Don't look at the source, look at the books that those people read. Google "dragon book compiler". or click here.

Also have good look at Writh's books and articles . I learned a lot from him and also the tiger Book

gee 55$ for a book . Its too much , I guess hacking the source is the cheaper way out .

If the source code is well written and commented well , then you might be able to do way without the books . I learned about XNA programming this way , the books were way too expensive so downlded the books source code from the site and figured out the contents of the books without actually reading them .

However the authour here seems to be very smart , there are no comments in the source code .But the source is quite readable , i think its possible to understand the entire thing with some exertion from your side.

Many of my college books are past the $50 (even past €50).

Good thing the book I have on compiler stuff is from my university (pdfs, be free! )

Hi,
However here in India , low price Asian Editons are available , so the cost is around only 10$ or less . I also buy second hand books , which are much cheaper . My rooms is therefore flooded with books .

The code says exactly what its doing more accurately than a bunch of comments, i dont like a bunch of misdocumented comments cluttering up my crystal clear source code.

I bought the dragon book in internet yesterday.(english second edition)

Engish is a foreign language for me, mybe it is a little difficult to read it.

who developped a compiler before, Would you like to talk about it , and give me some advices.

That sums up the value of comments , code written by you might be crystal clear to you , but not necesserily for someone else .

...and your code is only clear on the how, but not on what or why.

thats why my bootloader looks more like a book than a piece of code
If you have interest check it out here: http://code.google.com/p/the-kos/source ... t/boot.asm

Going back on-topic...
I plan on writing an compiler down the road, I've the dragon book but never got the time to fully read it
Knowing the LCC has a book and is well documented, i might be trying to look at its code when time comes

Ive used Gold parser (http://www.devincook.com/goldparser/) to create a C# sort of compiler and assembler before. Someone in IRC recently turned me on to ANTLR (http://www.antlr.org) I've not used it but it looks promising. Those groups would be a better place for info on compilers.

HI,

To the best of my knowledge most chinese people speak english well,
,...,& sorry to say that,most valuable books around computer science written in english ,so you need to improve your english skills
