Symbol Tables for ALLCOT (10 marks)

Enhance your parser such that it creates symbol tables. Again, please refer to the Assignment 3 of the year 2003-2004 together with the yacc.tar.gz archive.

To make things simple, one could avoid linked lists and use only records and arrays instead. You may have a look at the file mool-3.h in the yacc.tar.gz archive.

Alternatively, you can use data-structures provided by the glibc library.

At the end of the parsing, your parser should report on the contents of the symbol-tables. Here's an example using mool.y, mool.l, mool.h linked to mool-3.y, mool-3.l, mool-3.h.

[moreno@iguanodon yacc]$ make mool.out

[moreno@iguanodon yacc]$ ./bin/mool < test/p0.mool
