Bug ID: 105845
Summary: Provide a name mangling facility
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: eyalroz1 at gmx dot com
Target Milestone: ---
GCC, obviously, produces mangled names for (static-storage-duration) variables
and functions when it produces object files. However, it does not expose this
functionality to programs, i.e. it doesn't let a C++ program obtain the mangled
name of a function or variable.
I'm asking that it does offer that functionality. The specifics would probably
involve some bikeshed, but for example, it could be something like this:
* In the `abi::` namespace like `__cxa_demangle()`.
* One variant of the function would mangle a string
* Another variant of the function would mangle a C++ variable or function (and
the mangling function would be templated).

I don't think this is a bug of libstdc++.
Perhaps you may use extern "C" and __attribute__((alias("specified_name")) (can
be also spelled as [[gnu::alias("specified_name")]] since C++11 mode) as
workaround.

Well, it's not a bug, it's a feature request. But - I certainly won't bikeshed
about the choice of component.

I'm not trying to force a mangled name, I want to get the mangled name in
pre-existing code.
