Hi,
We're assessing many proposals to add "forwarding constructors" and
forwarding functions to C++0x; and I got a question.
In standard C++, constructors cannot be recursive functions. I'm
wondering whether the multiple entry-points implementation strategy
used
by GCC depends in anyway on the absence of recursive definition.
I think people have raised this before but some targets will never
support multiple entry points.
Things like:
_extern_function:
mr r0, r3
mr r3, r4
mr r4, r0
_extern_function_1:
...
blr
is not really supported on powerpc-darwin.
You might want to look into how gfortran implements multiple
entry-points
but IIRC the ENTRY construct in Fortran is now declared as obsolete and
really should not be used so I don't understand why C++ is trying to
add this.
