Introduction: 
  This repository maintains the coding tasks of "Compiler Principles", FZU, 2017 Fall.
  The basic of this repository is a compiler for Pascal language. We make some efforts
  on accommodating to the additional requirements of this experiment, including:

Lexer: 
  * 1.Analysing specific integer number, such as Oct, Bin, Hex.
  * 2.Warning if an integer is bigger than 2^31;
  * 3.Analysing type "string".

Grammatical Analysis: 
  * Based on the subset of "grammar.txt", create the SLR(1) analyse table;
  * Output the error to assigned log file;
  * Print the processing messages during analysing statements, including the 
    contents of stack and applied actions.
  * Append: 
    * Grammar of "Grammatical Analysis": grammar/parser_tasks/grammar.txt
    * Test data: slr1_tests/given_example.pas

IR Generating: 
  * Based on the subset of "grammar.txt", create the SLR(1) analyse table;
  * Output the error to assigned log file;
  * Print the processing messages during analysing statements, including the 
    contents of stack and applied actions;
  * Write the SDD of given grammar;
  * Generate the corresponding TAC(Three Address Code) based on SDD.
  * Append: 
    * Grammar of "IR Generating": grammar/ir_tasks/grammar.txt
    * Test data: ir_tests/example.pas

Running our demonstration: 
  * See ROADMAP for details.
