Introduction


This is a one-week workshop aimed at teachers in various colleges. This workshop is organized under the aegis of the GCC Resource Center of the Department of Computer Science and Engineering of IIT Bombay.

Proposed Pedagogy

Modern  day  compilers  are,   to  a  large  extent,  automatically generated  rather  than  hand-crafted.   This workshop  will  provide hands-on  experience  in  building  compilers through  the  use  of  compiler generation tools.  While the tools for generating compile front-ends, lex  and yacc, are now standard  textbook material, the workshop  will also  include  the use  of  a tools  called iburg  for generating back-ends. The main objective of this workshop is to teach how to build a compiler incrementally such that:

  • Each steps supports new source language features rather than a new phase in the compiler. In other words, each steps results in a complete working compiler which generates code which can be executed. We begin with a very small language consisting merely of expression.
  • Tools like  lex, yacc (or flex, bison), and iburg are used before the theory behind scanning, parsing, and instruction selection is covered.

The basic motivation behind this approach is to be able to strike a good balance between theory and practice and make the theory follow the practice instead of the other way round which is what happens in traditional courses.
Our choice of source language is loosely based on C while the target machine is MIPS as defined by the spim simulator (some sample spim programs collected from various resources available on the net). I

In  general, the  delivery plan  for  the workshop  will consists  of several rounds of:

  • Lectures to  introduce (certain aspects)  of the tools.
  • Laboratory exercises  to use the tools to implement a language with a given set of features.
  • Lectures that will utilize the experience gained in the laboratory exercises to provide the theoretical basis of compiler construction.
Pre-requisites


Participant should have taught some topics in compilers (such as, macroprocessors, linkers and loaders, scanning and parsing, semantic analysis).
Good knowledge of C and familiarity with Unix/Linux is a must.


Workshop Content

Theory
Practice
  1. Scanning. Expressing tokens through regular expressions, converting regular expressions to DFA, generating scanners from specifications, structure of generated scanners, efficient representation of scanning tables.
  2. Parsing. Expressing syntactic structure through grammars. LR parsing theory, generating parsers from specifications.
  3. Static Semantics. Using attributes for (i) type checking (ii)  calculating variable offsets (iii) Generating abstract syntax trees.
  4. Runtime Environments. Activation records, function prologues and epilogues for allocation and deallocation of activation records.
  5. Code Generation. Optimal code generation for expression trees. Generating code generators from specifications. Simple register allocation.
  6. Introduction to GCC. The compiler generation framework. Retargetability model. Inspecting intermediate represenations of program.
Using  the  compiler generation  tools lex, yacc , and iburg for generating MIPS code accepted by the spim simulator for the following language features:
  1. Constant expressions
  2. Expressions involving variables
  3. Assignment statements
  4. Array references
  5. Declarations
  6. Function calls

These experiments will be preceded by lab exercises on writing simple interpreters.
