问题
I'm working on a parser for C. I'm trying to find a list of all of the context-free derivations for C. Ideally it would be in BNF or similar. I'm sure such a thing is out there, but googling around hasn't given me much.
Reading the source code for existing parsers/compilers has proven to be far more confusing than helpful, as most that I've found are much more ambitious and complicated than the one I'm building.
回答1:
You could always use Annex A of the C11 standard itself. The freely available draft standard will work for your purposes, at http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf .
回答2:
This is an ANSI-C grammar, updated to C11 standard. Should serve your purpose.
