[cfe-dev] add a language to clang

[regis portalez]

Hi, 

 

I’m willing to add a new language in clang. 

 

I’d like to know what are the best practices before starting the actual
implementation. 

I’m already (kind of) familiar with clang/llvm, but I don’t want to waste an
excessive amount of time in trying lousy options. 

I synchronized clang on my local repository, and I read that
http://llvm.org/docs/tutorial/LangImpl1.html. 

 

I’d like to get feedbacks from people who actually did that kind of work,
and know which are the pitfalls. 

 

To make it short, these are my questions: 

-          Branching strategy : what is the best way? Should I branch the
whole llvm repository? 

-          Code writing: Should I start writing code directly, targeting a
small subset of the target language and iterate from that? Should I instead
think a lot about my stuff and consider writing code once I’m sure I’ll be
able to compile the entire language?

-          Commit : considering I’ve written a really good clang extension,
and I want that to make it public. How can I merge to the trunk?

 

Many thanks,
