[antlr-interest] Question: ANTLR and LLVM ... + Clang

[Ruslan Zasukhin]

Hi Guys,

Thank you very much for answers.

Okay, so about LLVM is clear ... It is compillers - code generation.

But exists yet  Clang --  C/C++/ObjC frontend

And I think Clang can be compared to ANTLR.
Right?

When one should prefer Clang vs ANTLR or reverse?
Your opinions?

Antlr is: lexer, parser, ast walker. LLVM - low level virtual machine
e.g. can generate and interpret it's bytecode and can generate
optimized cpu instructions also supports JIT. They have nothing in
common but they can be used to create a compiler. Pretty good one i
have to say.

Yes they can. However you still need to write some code. Also llvm is
C++ framework. There are some bindings though.

llvm doesn't provide what antlr provides.
