While reading the text Modern Compiler Implementation in C by Andrew Appel I came across the hierarchy of grammar given below.
The above diagram is very helpful in understanding the correlation among the various parser grammars. All the grammar above are context free grammars. From theory of computation texts, I have the following Chomsky hierarchy of grammars in my mind.
Now I wonder, how to correlate these two diagrams - a possible superposition, which shall show where exactly in the Chomsky hierarchy the parser grammars lie, and their extent with respect to the boundaries already defined by Chomsky hierarchy.
If possible, could you please as well suggest the resource from which I can develop more knowledge regarding this.
PS: After the comments and discussion in the answer by Yuval Filmus, I made an attempt to draw the situation:
Are the above diagrams which I have constructed as per my understanding correct? If they are not then could anyone please rectify it...
