/*
Clang indeX abstractions. The backing store for the following API's will be
- clangs PCH file (which contains AST's, or Abstract Syntax Trees). PCH files
- are created by the following command:
+ clangs AST file (currently based on PCH). AST files are created as follows:
- "clang -S -Xclang -emit-pch <sourcefile.langsuffix> -o <sourcefile.ast>".
+ "clang -emit-ast <sourcefile.langsuffix> -o <sourcefile.ast>".
- If the ast file format ends up diverging from the pch file format, we will
- need to add a new switch (-emit-ast). For now, the contents are identical.
-
Naming Conventions: To avoid namespace pollution, data types are prefixed
with "CX" and functions are prefixed with "clang_".
