Info on Lex/yacc Objective-c grammar

I am thinking, as a way to learn the use of lex/yacc,  to write a simple
profiler for objective-c programs, and I need the lex/yacc grammar for
objective-c language. I searched with googgle, but I found only the
grammar for old objective-C for Mac.
Has anyone the grammar for "standard" objective-c language, where
standard means "all platforms"?
Surely the fsf used it to build the objc part of gcc.
Regards.

GIYF!* I did a search for Objective-C grammar, and the top several hits all
looked quite promising.

Besides, I think you are labouring under a misapprehension about the
history of Objective-C. If I recall correctly, Objective-C was
originally popularised by NextSTEP (though they did *not* originate
it), and NeXT/Apple have been the driving forces in the evolution (or
even the continued existence) of Objective-C. There isn't a "standard"
Objective-C, as such. In fact, since Objective-C 2.0 is driven by
Apple, I would say that their grammar is as definitive as anyone's.

What do you mean by "all platforms"? The language itself is portable
to "all platforms". I have an Objective-C compiler on my FreeBSD
boxes, my Linux boxes, and (back when I had one) my Solaris boxes. The
libraries Apple ships are for Mac OS X, but the compiler is still the
same FSF GCC based compiler.
