#ident preprocessor directive is ignored ?

Clang Frontend
#1

Hi folks!

The #ident preprocessor directive seems to be missing (actually it seems to be /ignored/) - is it a known behavior ?

Ie. the following program:

#ident "$$Description: ident-test $$"
int main(void) { return 0; }

Produces a binary without the given RCS string:

$ ident ident-test-clang
ident-test-clang:

[ Yes, I admit that the venerable RCS strings are a bit outdated, but there is no other standard way AFAIK to include useful meta-data in libraries, such as version/build information. ]

Cheers,
Xavier

Clang parses #ident and then throws the results away. It's never been important enough to anyone to actually pass this information through.
