gcc vs g++ and linking with as

[Dave Hansen]

This is the name mangling that g++ uses to resolve overloaded functions.
To prevent this, declare the assembly functions as extern "C" in the
C++ code.  For example:

   extern "C" asm_fn();

HTH.  Regards,

Not using stdlib  (-nostdlib)

We have some code in assembler, and some in C.
Compiling with as,gcc and linking with ld works fine.
Compiling with as,g++ and linking with ld does not work,
  undefined symbols for those things written in assembler.

The .o files output from g++ compilation have exported symbols that
end in '__Fv' whereas the assembler output .o files don't have
'__Fv' on the symbols.  Is that the problem?  Is there
some way to make it work?  What is __Fv?


An alternative might be to put the assembly code in
C/C++ wrapper functions.  Any hints/comments that
would be appreciated also.
