Is GCC a LALR(1) compiler?

Can anyone deny/co开发者_开发百科nfirm this??

It can't be, at least not entirely -- the C grammar doesn't fit LALR(1).

The Gcc parser is a LALR grammar file for Bison, which is a LALR parser generator. Therefore, if you want to say that, gcc is LALR.

Yes, GCC is LALR.

"The Gcc parser is a LALR grammar file for Bison, which is a LALR parser generator. Therefore, if you want to say that, gcc is LALR."

This discussion (though old) says gcc is LALR while for C++ it is a hand-written recursive descent one.

The quote above is out of date. All parser of GCC is hand written now. And I am pretty sure cpp is a lalr(k) parser.
