The third project involves writing the semantic analyzer for the compiler that was begun in the previous projects. To simplify the semantic error checking, you are to remove the ability to have multiple functions from the grammar and the ability to make function calls.
In order to perform semantic analysis, the symbol table must be completed in this project. The 70 points that you will receive for the functionality portion of your grade on this project will be based on how many of the following errors that you can detect:
Test data that contains each of the following errors will be provided.
This project requires modification to the bison input file, so that it defines the semantic checks necessary to produce these errors and the inclusion of a symbol table to keep track of the declared identifiers.
Variables and parameter names have local scope. The scope rules require that all names be declared and prohibit duplicate names within the same scope. The type correspondence rules are as follows:
Like syntax errors, the compiler should display the semantic errors in the compilation listing, after the line in which they occur.
