C++ ABI?

C++ ABI?

[Tom Horsley]

OK, I give up! The gcc 3.2 release trumpets its compatibility with the
so-called C++ ABI, yet the http://gcc.gnu.org/gcc-3.2/c++-abi.html web page
says ABSOLUTELY NOTHING about what the C++ ABI is, who defined it, where to
get a copy of it, how to read about it, etc.

I have never managed to turn up anything in any web search for this mythical
document other than references to its existance. The document itself seems
to be shrouded in absolute secrecy.

Help! Can anyone point me to this thing? Thanks.

That page does need a link to it.

It seems nobody has dealt with this yet, so I have committed the patch
below.

OK, I've been there before, but everything I can see on that page
seems to be Itanium related. If there are pointers to architecture
neutral (or even IA32 specific) ABI info on that page,
I can't see it.

Perhaps I need to memorize everything that all the links point
at before the big picture becomes clear to me :-).

It was created for the sake of Itanium, but it is a generic standard.

Anything labeled gABI is "general ABI," anything labeled psABI is
"processor-specific" ABI.  It's a general approah, and Itanium "just happens"
to use it as its native ABI.
