[cfe-dev] Questions about Clang's API

[Zhang via cfe-dev]

Hi:
I'm relatively new to the libClang API. Below are a few questions I have:
- I'm currently using ClangTool's ::buildASTs to construct AST from CompilationDatabase. Is there any API to do this in parallel to speed up this process?
- From previous step I can obtain an array of ASTUnit. AFAIK I should then get the ASTContext of this ASTUnit then call ASTContext::getTranslationUnitDecl() , my question is what is the next step to run my RecursiveASTVisitor on it?
- My third question is that is Clang's APIs generally thread-safe? As in can I safely do step 2 across multiple threads given that I dont share ASTContext among threads?
