A Compiler Writing Journey
In this Github repository, I'm documenting my journey to write a self-compiling compiler for a subset of the C language. I'm also writing out the details so that, if you want to follow along, there will be an explanation of what I did, why, and with some references back to the theory of compilers.
But not too much theory, I want this to be a practical journey.
Here are the steps I've taken so far:
- Part 0 : Introduction to the Journey
- Part 1 : Introduction to Lexical Scanning
- Part 2 : Introduction to Parsing
- Part 3 : Operator Precedence
- Part 4 : An Actual Compiler
- Part 5 : Statements
- Part 6 : Variables
- Part 7 : Comparison Operators
- Part 8 : If Statements
- Part 9 : While Loops
- Part 10 : For Loops
- Part 11 : Functions, part 1
- Part 12 : Types, part 1
- Part 13 : Functions, part 2
- Part 14 : Generating ARM Assembly Code
- Part 15 : Pointers, part 1
- Part 16 : Declaring Global Variables Properly
- Part 17 : Better Type Checking and Pointer Offsets
- Part 18 : Lvalues and Rvalues Revisited
- Part 19 : Arrays, part 1
- Part 20 : Character and String Literals
- Part 21 : More Operators
- Part 22 : Design Ideas for Local Variables and Function Calls
- Part 23 : Local Variables
- Part 24 : Function Parameters
- Part 25 : Function Calls and Arguments
- Part 26 : Function Prototypes
- Part 27 : Regression Testing and a Nice Surprise
- Part 28 : Adding More Run-time Flags
- Part 29 : A Bit of Refactoring
- Part 30 : Designing Structs, Unions and Enums
- Part 31 : Implementing Structs, Part 1
- Part 32 : Accessing Members in a Struct
- Part 33 : Implementing Unions and Member Access
- Part 34 : Enums and Typedefs
- Part 35 : The C Pre-Processor
-
Part 36
:
breakandcontinue - Part 37 : Switch Statements
- Part 38 : Dangling Else and More
- Part 39 : Variable Initialisation, part 1
- Part 40 : Global Variable Initialisation
- Part 41 : Local Variable Initialisation
- Part 42 : Type Casting and NULL
- Part 43 : Bugfixes and More Operators
- Part 44 : Constant Folding
- Part 45 : Global Variable Declarations, revisited
- Part 46 : Void Function Parameters and Scanning Changes
-
Part 47
: A Subset of
sizeof -
Part 48
: A Subset of
static - Part 49 : The Ternary Operator
- Part 50 : Mopping Up, part 1
- Part 51 : Arrays, part 2
- Part 52 : Pointers, part 2
- Part 53 : Mopping Up, part 2
- Part 54 : Spilling Registers
- Part 55 : Lazy Evaluation
- Part 56 : Local Arrays
- Part 57 : Mopping Up, part 3
- Part 58 : Fixing Pointer Increments/Decrements
- Part 59 : Why Doesn't It Work, part 1
- Part 60 : Passing the Triple Test
- Part 61 : What's Next?
- Part 62 : Code Cleanup
There isn't a schedule or timeline for the future parts, so just keep checking back here to see if I've written any more.
Copyrights
I have borrowed some of the code, and lots of ideas, from the SubC compiler written by Nils M Holm. His code is in the public domain. I think that my code is substantially different enough that I can apply a different license to my code.
Unless otherwise noted,
- all source code and scripts are (c) Warren Toomey under the GPL3 license.
- all non-source code documents (e.g. English documents, image files) are (c) Warren Toomey under the Creative Commons BY-NC-SA 4.0 license.
