[cfe-users] Compile from source code string
I wanna use regular functionality of clang but instead of passing path to the source I want to pass string as source code. Yes, it's preferably a code that uses clang api and not just call to clang with source that was put into input, as source files are usually big. Googled that, but not really successfully. No good source of info about that or code that's outdated. Would really appreciate any help. ___ cfe-users mailing list cfe-users@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users

If it's possible, then of course LibClang as it's backward compatible, but
I know that it's restricted in functionality, so if LibClang don't give
such freedom, then LibTooling.

Thanks for the advice! This should work on unix, but what's about other
systems? That's why I wanted to go with code, because I target at least
Linux, Macos and Windows, and with code solution it'll be no different to
support all of them as well as it'll be bit more secure, I think.

Re: [cfe-users] Compile from source code string
Right now I'm in process of trying this approach:
Copy the code from cc1_main, write my own SourceManager and set it to
CompilerInstance with setSourceManager().
