...the C++ demangler, but it ended up being too slow. On that note, the demangler is a performance bottleneck for lldb. Going to the fast demangler over the system one was a big performance win. Maybe the system demangler is fast enough nowadays, but if it isn't then we can't get rid of the FastDemangler.

...As far as future plans for this file, I have a few more refactorings and performance improvements that I'd like to get through. After that, it might be interesting to try to replace the FastDemangle.cpp demangler in LLDB with this, to restore the one true demangler in the source tree. The FastDemangler.cpp is only partially completed, and calls out to ItaniumDemangle.cpp in llvm (which is a copy of cxa_demangle.cpp) if it fails to parse the symbol. Any thoughts here would be appreciated! Thanks, Erik -------------- next part -------------- commit e526dffc812b303734fbce5644f2d2ae4c4ca3dc Author...
