3 """A tool for extracting a list of symbols to export
5 When exporting symbols from a dll or exe we either need to mark the symbols in
6 the source code as __declspec(dllexport) or supply a list of symbols to the
8 list of link inputs and deciding which of those symbols need to be exported.
10 We can't just export all the defined symbols, as there's a limit of 65535
11 exported symbols and in clang we go way over that, particularly in a debug
12 build. Therefore a large part of the work is pruning symbols either which can't
15 importing these symbols anyway.
26 # Define functions which extract a list of symbols from a library using several
33     process = subprocess.Popen(['dumpbin','/symbols',lib], bufsize=1,
38         # Look for external symbols that are defined in some section
50         # Look for external symbols that are defined in some section
57     process = subprocess.Popen(['llvm-readobj','-symbols',lib], bufsize=1,
120 # identifier/type mangling we can decide which symbols could possibly be
149     # Keep mangled llvm:: and clang:: function symbols. How we detect these is a
