I've been looking at the objects etcetera produced by dmd, and using D's function demangle in std.demangle to decrypt some of the symbols found in such objects by nm.

http://sourceware.org/binutils/docs-2.22/binutils/nm.html

While demangle does produce a demangled version of some symbols, it does not in other cases where they nevertheless look as if they may be mangled names of some kind. I considered that perhaps they are C++ mangled names, but have been unable to get nm to unmangle them, even though it nominally knows about C++ name mangling.

Is there a better analog of demangle I can use to translate back some of these more intractable mangled names? I tried the one in core.demangle but it did no better. Or is there somewhere I could determine the demangling rules and implement them for myself? Any suggestions will be gratefully received.

Here are some examples that are not demangled by std.demangle.demangle :

_D13libd_demangle12__ModuleInfoZ
_D15TypeInfo_Struct6__vtblZ
_D3std5stdio12__ModuleInfoZ
_D3std6traits15__T8DemangleTkZ8Demangle6__initZ
_D47TypeInfo_S3std6traits15__T8DemangleTkZ8Demangle6__initZ
