[cfe-dev] Keeping AST data for includes

[Vladimir Kirillov]

Hello, cfe-dev!

While processing big source code trees with ASTFrontendAction and custom
ASTConsumer, same include files are getting hit and parsed all over and
over again.
Is there any technique (except precompiled header) to prevent such
actions? Like keeping header-related AST data and referencing it within
next files' AST?


Thanks!
