[cfe-dev] manipulating @llvm.var.annotation in AST?

[Mark Brown]

Theres a direct way todo this? How can I avoid writing a AST file? When I
run

clang -cc1 -load ~/llvm/Release+Asserts/lib/libPrintFunctionNames.so -plugin
print-fns test_file.c
or
clang -cc1 -load ~/llvm/Release+Asserts/lib/libPrintFunctionNames.so -plugin
print-fns test_file.c -S -emit-llvm

I don't get any output, just my own printouts.
