Does g++ have option to disable function name commingle. When I compile
like:

g++ -S Test.cpp

the file Test.s has function name commingled. For example, function name
foo becomes like __foo79emskd8. Is there any options which output function
name as original instead of commingled name? Thanks in advance.

I think you mean "name mangling".

Try asking in a g++ newsgroup.

Try including the declaration and definition of your function(s) in
an extern "C" block:
extern "C" {
void foo(int i);
}
This will disable the name-mangling of C++ for compatibility with C.

This is as far as you can get with portable C++.

Maybe the FAQ can help:
http://www.parashift.com/c++-faq-lit...c-and-cpp.html

In general, you want to prefix the function with:
extern "C" void foo() // etc.

However, even with C functions, some compilers will prefix the
exported name with an underscore.

But it won't do what he asked for, which is use the original function
name. It mangles the name by prepending an underscore.

It will on many platforms, although this detail is outside the
scope of the standard, right?

And as I indicated next in what you omitted to quote:[color=blue]
> This is as far as you can get with portable C++[/color]
inviting the OP to look for a platform-specific solution if
he needs to go "further" in removing any remaining decoration.

So, Pete, I'm not sure in what way your reply here was intended
to be informative. But in my opinion this is one of many posts of
yours that could have used being written in a less arrogant tone.

Sorry,
Ivan
