--- Comment #2 from Dan Olson <gorox@comcast.net> ---
I would think yes, D symbols emitted to the object file on OS X should have extra underscore.  And .mangleof should produce the symbol without the extra underscore as it does today.

extern(C++) has opposite problem.  The extra underscore is present in object file (correct) but is also present in .mangleof symbol.  It should be stripped from the .mangleof symbol.  Note: ldc merge-2.067 does this now which caused test compilable/test7030.d to fail, which is how I got here.  I think LDC is correct.

-- demo --
void dfun(int);
extern(C++) void cxxfun(int);
extern (C) void cfun(int);

pragma(msg, dfun.mangleof);
pragma(msg, cxxfun.mangleof);
pragma(msg, cfun.mangleof);

dmd 2.067 produces:
_D10showmangle4dfunFiZv
__Z6cxxfuni
cfun

where obj file has these symbols:
                 U _D10showmangle4dfunFiZv
                 U __Z6cxxfuni
                 U _cfun

https://github.com/dlang/dmd/commit/db2976599db44f2163986ba9cb541afd7cfa8471 fix Issue 8207 - extern(D) symbols should include another underscore

    1. Removed ABI name fiddling from the front-end.
    2. Removed `Target.prefixName` and C++ tests for matching `__Z`.
    3. Prepend prefixes for C++ and D symbols in the backend only
       for the targets that require it (Win32, OSX).
    4. Removed `RTLSYM__DINVARIANT` runtime library symbol, name is now
       the same on all targets.
    5. Correctly set C++ mangling on `LINK.cpp` symbols, before they
       were all being set as D mangled symbols.
    6. Use System mangling as synonym for do not modify symbol.
    7. Added workaround for `extern(D) ___tls_get_addr`.
