/*
Provides a shared context for creating translation units.
It provides two options:
- excludeDeclarationsFromPCH: When non-zero, allows enumeration of "local"
declarations (when loading any new translation units). A "local" declaration
is one that belongs in the translation unit itself and not in a precompiled
header that was used by the translation unit. If zero, all declarations
will be enumerated.
Here is an example:
\code
// excludeDeclsFromPCH = 1, displayDiagnostics=1
Idx = clang_createIndex(1, 1);
// IndexTest.pch was produced with the following command:
// "clang -x c IndexTest.h -emit-ast -o IndexTest.pch"
TU = clang_createTranslationUnit(Idx, "IndexTest.pch");
// This will load all the symbols from 'IndexTest.pch'
clang_visitChildren(clang_getTranslationUnitCursor(TU),
TranslationUnitVisitor, 0);
clang_disposeTranslationUnit(TU);
// This will load all the symbols from 'IndexTest.c', excluding symbols
// from 'IndexTest.pch'.
char *args[] = { "-Xclang", "-include-pch=IndexTest.pch" };
TU = clang_createTranslationUnitFromSourceFile(Idx, "IndexTest.c", 2, args,
0, 0);
clang_visitChildren(clang_getTranslationUnitCursor(TU),
TranslationUnitVisitor, 0);
clang_disposeTranslationUnit(TU);
\endcode
This process of creating the 'pch', loading it separately, and using it (via
-include-pch) allows 'excludeDeclsFromPCH' to remove redundant callbacks
(which gives the indexer the same performance benefit as the compiler).
