-Itanium Name Demangler Library
-==============================
-
-Introduction
-------------
-
-This directory contains the generic itanium name demangler library. The main
-purpose of the library is to demangle C++ symbols, i.e. convert the string
-"_Z1fv" into "f()". You can also use the CRTP base ManglingParser to perform
-some simple analysis on the mangled name, or (in LLVM) use the opaque
-ItaniumPartialDemangler to query the demangled AST.
-
-Why are there multiple copies of the this library in the source tree?
----------------------------------------------------------------------
-
-This directory is mirrored between libcxxabi/demangle and
-llvm/include/llvm/Demangle. The simple reason for this is that both projects
-need to demangle symbols, but neither can depend on each other. libcxxabi needs
-the demangler to implement __cxa_demangle, which is part of the itanium ABI
-spec. LLVM needs a copy for a bunch of places, but doesn't want to use the
-system's __cxa_demangle because it a) might not be available (i.e., on Windows),
-and b) probably isn't that up-to-date on the latest language features.
-
-The copy of the demangler in LLVM has some extra stuff that aren't needed in
-libcxxabi (ie, the MSVC demangler, ItaniumPartialDemangler), which depend on the
-shared generic components. Despite these differences, we want to keep the "core"
-generic demangling library identical between both copies to simplify development
-and testing.
-
-If you're working on the generic library, then do the work first in libcxxabi,
-then run the cp-to-llvm.sh script in src/demangle. This script takes as an
-argument the path to llvm, and re-copies the changes you made to libcxxabi over.
-Note that this script just blindly overwrites all changes to the generic library
-in llvm, so be careful.
-
-Because the core demangler needs to work in libcxxabi, everything needs to be
-declared in an anonymous namespace (see DEMANGLE_NAMESPACE_BEGIN), and you can't
-introduce any code that depends on the libcxx dylib.
-
-Hopefully, when LLVM becomes a monorepo, we can de-duplicate this code, and have
-both LLVM and libcxxabi depend on a shared demangler library.
-
-Testing
--------
-
-The tests are split up between libcxxabi/test/{unit,}test_demangle.cpp, and
-llvm/unittest/Demangle. The llvm directory should only get tests for stuff not
-included in the core library. In the future though, we should probably move all
-the tests to LLVM.
-
-It is also a really good idea to run libFuzzer after non-trivial changes, see
-libcxxabi/fuzz/cxa_demangle_fuzzer.cpp and https://llvm.org/docs/LibFuzzer.html.
