[cfe-dev] Help with clang AST matchers: find semicolon after a decl statement

[Frederico Araujo]

I found the problem!

I forgot to update my make file to link against the ARCMigrate library.
I realized that after adding -I$(LLVM_SRC_PATH)/tools/clang/lib/ARCMigrate
to my CLANG_INCLUDES, I also had to add -lclangARCMigrate to my CLANG_LIBS,
which solved the problem.
I wonder why Transforms.h isn't included in clang's tools build directory?

So, in conclusion, answering my first question, the following code can be
used to find the location just after the semicolon:

*SourceLocation SemiLoc =
clang::arcmt::trans::findSemiAfterLocation(D->getLocEnd(),
D->getASTContext());*

Regards,
Fred
