llvm dev - Aug 2018 - Put ToolInvoker Output Into a String

Hello!

    So I am running clang programmatically using clang::tooling::ToolInvocation,
however I dont want anything to touch the disk. I am able to read from a virtual
file using clang::tooling::ToolInvocation::mapVirtualFile , however I dont know
how to output to a virtual file or just to an std::string or char* , I tried
passing -o out.S -ivfsoverlay out.S but it still writes to disk and as far as I
can tell does not write to the memory I created.

If this isn't the right place for this post or if I need to clarify
something please let me know!

Thank you

I think you want to be sending questions about clang and clang-related tooling
questions to the cfe-dev@ mailing list instead.

Thank you, I will re-post there!
