When you create a parser via ANTLR you specify the output language of the resulting recursive descent parser, at the moment there exists no C++ output template to my knowledge, thus you would have to generate the parser as C code for which a template exists. The runtime support should be there, at least partially but it won't u...

We are looking for an open source C++ parser other than g++ if possible. Clang would be great but its C++ support is still some way away and we need something that works or nearly works now. Does anyone have any experience with ANTLR for parsing C++ and for extending their C++ parser? Any other feedback on ANTLR in general would be welcome too.

Hi, I've not got any experience using ANTLR to parse C++, however, you will find that there only exists a C code generator for ANTLR and NOT a C++ one.

Has anyone written a grammar for LLVM for ANTLR. I mean an ANTLR grammar that parses LLVM instructions. Is an LLVM grammar available for any other parsing tool? Surinder

Thanks, You need a lot more than a traditional parser to parse c++, you have to do full template instantiation, partial template specialization etc just to be able t...

For a LL(1) parser, it might be a little bit difficult to parse complex grammar like C++, but it might work. ANTLR worked great when other codes were written in Java, but it was a little bit painful when using other languages like python. I worked on it two years ago. I guess they might have some improvement now. Haohui On 07/11/2009 02:40 PM, Vikram S. Adve wrote: > We are looking for an open source C++...

Right, I understand that. I was hoping there was such an implementation using ANTLR since it looks like a fairly mature project. I'm not sure how stable or mature Elsa is (but comments to clarify that would be appreciated.). E.g., a quick scan of their Web page shows the comment that they only have a partial type checker. It also says their template instantiation is i...

...very limited if not to say non-existent. I would very much appreciate any hint on what I'm doing wrong. Both makefiles also change the compiler and linker flags after including the Makefile.common if that's of any relevance: CXXFLAGS += -I/usr/local/include LDFLAGS += -L/usr/local/lib -lantlr3c I'm using llvm 2.5 and building with gcc 3.4.5, gnu make 3.81 on, may Stallman forgive me, windows xp using mingw/msys. LLVM itself compiled without problems though so I'm quite sure it's just me doing something wrong rather than my setup. thanks, Stefan

Hi, I am a complete newbie to LLVM. I have an ANTLR parser, that outputs an AST. I want to comvert this AST to a LLVM IR, Can someone point me some relevant documentation/examples/ etc. on how to go about doing this?

Howdy, I just finished a book called Language Implementation Patterns but I ran out of room at 400 pages before I could squeeze in an LLVM example. I left a link in the book to the ANTLR wiki so I can slap something together: http://www.antlr.org/wiki/display/ANTLR3/LLVM The code is good but the description was slapped together I'm afraid (i.e., don't take it as an example of the book quality. ha!). The example is cool because the same generator can emit LLVM IR or C cod...
