did anyone ever debug a c/c++ compiler?
Please support our C++ advertiser: Intel Parallel Studio Home

Is there any open source c/c++ compilers what can be debugged easily? I wanna know more info about the common knowladge about c/c++ compilers.
I am from China. I love computer science!

There are plenty of open source C/C++ compilers. They are fairly complex bits of code, so the notion of "debugged easily" depends on your notion of what is "easy". However, the information on how they work is well documented.
If you want to debug compilers, and you have skills with that, offer your services to the development team of one of the open source compilers.

The key parts of most compilers are written in C itself, or in ASM.
The open compilers are well documented, but compilers are generally very complex indeed.

Bullshit.

The first compilers were written in assembly language as building a self-hosting compiler is a bootstrapping problem
Since the 1970s it has become common practice to implement a compiler in the language it compiles and C has historically been a popular choice of implementation language.

You can write the lion's share of a compiler in any language you please. The only real restriction would be the code generator, where you need a language that can write to your target format.

i didnt say that you couldnt, i said "most compilers" which is true.
