Issue ID: 24426
Summary: ddemangle.exe appears to not demangle any mangled
symbols
Product: D
Version: D2
Hardware: x86_64
OS: Windows
Status: NEW
Severity: normal
Priority: P1
Component: tools
Assignee: nobody at puremagic.com
Reporter: sturtivant at gmail.com
ddemangle.exe supplied with DMD64 Windows does not appear to do what it says it
should do. e.g.
```
>echo ?complicated@@YAHH at Z
?complicated@@YAHH at Z
>echo ?complicated@@YAHH at Z | ddemangle
?complicated@@YAHH at Z
>undname ?complicated@@YAHH at Z
Microsoft (R) C++ Name Undecorator
Copyright (C) Microsoft Corporation. All rights reserved.
Undecoration of :- "?complicated@@YAHH at Z"
is :- "int __cdecl complicated(int)"
```
Even with file input, ddemangle appears to do nothing but echo the input.
(Input file simply echoed.)
```
