demangling tree back into a mangled string.
Also, extend the demangling API in a few obvious
ways, and simplify testing for failure in the
node-returning APIs by having them simply return
null instead of a spurious Failure node.
Also, preserve slightly more information in the
demangling tree. The goal here is eventually to
always allow a perfect round-trip through the
demangler parse tree. This patch gets us close,
but we're not quite there yet.
Tests to follow.
Swift SVN r24473
The new demangler is in the "swift/SIL/Demangle.{h|cpp}" files, and in the swift::Demangle namespace, which has two public entry points:
std::string demangleSymbol(llvm::StringRef mangled);
std::string demangleType(llvm::StringRef mangled);
This was necessary to support the need for LLDB to demangle Swift symbol (and type) names
Test case is included
Swift SVN r6547
