I don't know if there's a good way to do that. Because debuggers need
to be able to see across multiple translation units, this is implemented
internally as constructing one giant AST that contains everything for
the entire program. LLDB has no notion of a per-module AST, so it would
be hard to make this work.
That's not how it's implemented now. The code actually iterates through
all the modules and dumps each one in turn.
result.GetOutputStream().Printf("Dumping clang ast for %" PRIu64
" modules.\n",
(uint64_t)num_modules);
for (size_t image_idx = 0; image_idx < num_modules; ++image_idx) {
if (m_interpreter.WasInterrupted())
break;
Module *m = target->GetImages().GetModulePointerAtIndex(image_idx);
SymbolFile *sf = m->GetSymbolVendor()->GetSymbolFile();
sf->DumpClangAST(result.GetOutputStream());
}
In fact, it looks like this command already supports specifying the
exact module to dump (either by basename or full path).
