--- Comment #9 from Rainer Schuetze <r.sagita...@gmx.de> --- > Support was added in binutils 2.25 I've build this version, but noticed that it doesn't demangle full text files, just the arguments given on the command line. Instead, it reports "Internal error: no symbol alphabet for current style". That has an easy fix, though. As cxxfilt will very likely never support compressed symbols aswell as MS mangled symbols, I've compiled my own version supporting all 3 manglings (D/gcc/cl) including compression. Disassembly with demangled symbols is now enabled if the global option "Demangle symbols in linker messages/disassembly" is checked. Try it in https://github.com/D-Programming-Language/visuald/releases/tag/v0.3.42-beta2 --
