Compiler construction tools
Compiler construction tools were introduced to aid in the development of compilers. These tools include scanner generators, parser generators, syntax-directed translation engines, and automatic code generators. Scanner generators produce lexical analyzers based on regular expressions to recognize tokens. Parser generators take context-free grammars as input to produce syntax analyzers. Syntax-directed translation engines associate translations with parse trees to generate intermediate code. Automatic code generators take intermediate code as input and output machine language. These tools help automate and simplify the compiler development process.
Techniques & applications of Compiler
A compiler is a program that translates a program written in a source language into an equivalent program in a target language. It has two major phases: analysis and synthesis. The analysis phase creates an intermediate representation using tools like a lexical analyzer, syntax analyzer, and semantic analyzer. The synthesis phase creates the target program from this representation using tools like an intermediate code generator, code optimizer, and code generator. Techniques used in compiler design like lexical analysis, parsing, and code generation have applications in other areas like text editors, databases, and natural language processing.
Phases of compiler
The document describes the main phases of compilation: lexical analysis, syntax analysis, semantic analysis, intermediate code generation, code optimization, and code generation. Lexical analysis converts the source code into tokens. Syntax analysis groups the tokens into a parse tree. Semantic analysis checks that the program is semantically correct. Intermediate code generation outputs machine-independent code. Code optimization improves the intermediate code. Finally, code generation converts the optimized code into machine-dependent target code.
Compiler design
The document defines and describes compilers and their key phases and components. A compiler translates a high-level language into machine-level language. It has two main phases - analysis and synthesis. The analysis phase performs lexical, syntax and semantic analysis to generate an intermediate representation. The synthesis phase generates code from this representation, including intermediate code, optimization, and final code generation. Compilers have a front-end, middle-end and back-end. The output can be for native or cross platforms, or target a virtual machine. Compiler correctness and related techniques like assemblers are also discussed.
Error detection recovery
The document discusses error detection and recovery in compilers. It describes how compilers should detect various types of errors and attempt to recover from them to continue processing the program. It covers lexical, syntactic and semantic errors and different strategies compilers can use for error recovery like insertion, deletion or replacement of tokens. It also discusses properties of good error reporting and handling shift-reduce conflicts.
Phases of-compiler
The document discusses the phases of a compiler and how a program is processed. It explains that a source program goes through multiple phases including lexical analysis, syntax analysis, semantic analysis, intermediate code generation, optimization, and code generation to produce target machine code. The compiler performs analysis and synthesis to process the source code in 6 main phases and generate executable code from the input source code.

Compiler Construction Course - Introduction
The document provides an overview of compilers and interpreters. It discusses how compilers translate source code into target code like machine language while interpreters directly execute source code. It also describes the different stages of compilation from preprocessing to assembly and linking. Key points made include:
- Compilers translate entire programs at once while interpreters translate and execute one line at a time.
- Compilers generate error reports after full translation while interpreters stop at the first error.
- Compilation takes more time than interpretation but executed code runs faster.
- Some languages use hybrid approaches that interpret translated bytecode for faster execution.
- Larger programs are compiled in pieces and linked together with libraries before execution.
Compilers
A compiler is a program that translates a program written in one language into an equivalent target language. The front end checks syntax and semantics, while the back end translates the source code into assembly code. The compiler performs lexical analysis, syntax analysis, semantic analysis, code generation, optimization, and error handling. It identifies errors at compile time to help produce efficient, error-free code.

Introduction to compilers
A compiler is a computer program that translates a program written in a source language into an equivalent program in a target language. The compilation process involves scanning the source code, parsing it, performing semantic analysis, generating intermediate code, optimizing the code, and finally generating the target code. Key data structures used in compilers include symbol tables to store information about identifiers, literal tables to store constants, and parse trees to represent the syntactic structure of the program.
Chapter 1 1
The document describes the structure and process of a compiler. It discusses the major phases of a compiler including scanning, parsing, semantic analysis, code generation and optimization.

Open course(programming languages) 20150225
This document discusses programming language parsers and abstract syntax trees. It contains the following key points:
1) A parser takes a sequence of tokens as input and outputs a parse tree representing the syntactic structure according to a grammar. The tree structure is convenient for computers to interpret even if cumbersome for humans.
2) Parsers can build the parse tree either top-down or bottom-up. An abstract syntax tree then simplifies the parse tree, removing details not needed for semantic analysis.
3) Tools like Python Lex-Yacc can generate parsers from grammar rules and token definitions, allowing the construction and use of parsers and abstract syntax trees for programming languages.
The History of Programming Languages
This document is a timeline from 1960 to 2004 that highlights 50 major programming languages. It was created by Éric Lévénez and augmented by O'Reilly authors and others. For over 50 years, O'Reilly has provided technical information to developers as new languages have emerged and evolved, to help them learn something new or answer tough questions.

- What constitutes a program and the act of programming.
- The evolution of programming languages from machine language to modern high-level languages.
- Different programming paradigms such as procedural, functional, object-oriented, and event-driven programming.
- Examples of popular languages like COBOL, BASIC, FORTRAN, Pascal, C/C++.
- Key factors in evaluating programming languages like readability, reliability, and cost.
- A brief history of the C programming language.
4 evolution-of-programming-languages
The document discusses the evolution of programming languages from first to third generation languages. First generation languages were machine code using binary, while second generation introduced assembly language with mnemonic codes. Third generation languages brought features like loops and conditionals, making code easier to write but requiring compilers or interpreters to convert to machine code. Some examples of early third generation languages discussed are FORTRAN, BASIC, COBOL, and PASCAL.
Optimisation
This document discusses optimization problems and their solutions using calculus. It provides examples of finding maximum and minimum values for functions by taking the derivative and setting it equal to zero. The key steps are to identify what is being optimized (highest, longest, etc.), write an equation relating the variables, take the derivative of that equation, set the derivative equal to zero to find critical points, and then determine if those points are maxima or minima using the second derivative test or nature of the function.
Back patching
This document discusses backpatching and syntax-directed translation for boolean expressions and flow-of-control statements. It describes using three functions - Makelist, Marklist, and Backpatch - to generate code with backpatching during a single pass. Boolean expressions are translated by constructing syntax trees and associating semantic actions to record quadruple indices for later backpatching. Flow-of-control statements like IF and WHILE are handled similarly, using marker nonterminals to record quadruple numbers for backpatching statement lists.

Programming languages
The document summarizes different types of programming languages:
- Machine languages and assembly languages were early languages that mapped directly to computer hardware. They were inefficient for programmers.
- High-level languages like procedural languages made programming easier by using English-like syntax but were less efficient. Problem-oriented languages focused on solving specific problems.
- Compilers convert an entire program to machine code while interpreters convert each statement, making compilers generally more efficient once converted.
Syntax
Syntax defines the grammatical rules of a programming language. There are three levels of syntax: lexical, concrete, and abstract. Lexical syntax defines tokens like literals and identifiers. Concrete syntax defines the actual representation using tokens. Abstract syntax describes a program's information without implementation details. Backus-Naur Form (BNF) uses rewriting rules to specify a grammar. BNF grammars can be ambiguous. Extended BNF simplifies recursive rules. Syntax analysis transforms a program into an abstract syntax tree used for semantic analysis and code generation.
Chapter Seven(2)
The document discusses runtime environments and memory management techniques for programming languages. It covers stack-based vs dynamic environments, parameter passing mechanisms like pass by value and reference, and garbage collection algorithms. Dynamic memory allocation uses a heap structure with malloc and free functions. Object-oriented languages require special runtime support for objects, inheritance etc. Fully dynamic environments are needed for functional languages that allow nested functions.
The dag representation of basic blocks
The document discusses directed acyclic graphs (DAGs) and how they can be used to represent basic blocks of code. It describes how a DAG is constructed from three-address statements, with nodes labeled by variables, operators, or unique identifiers. Interior nodes represent computed values and leaves represent variables or constants. The DAG construction process creates nodes and links them based on the statements. DAGs are useful for detecting common subexpressions, determining which variables are used in a block, and which statements compute values used outside the block. Array accesses, pointers, and procedure calls require additional rules when constructing DAGs to properly capture dependencies.
Compiler Optimization Presentation
Compiler optimization transforms programs to equivalent programs that use fewer resources by applying techniques like:
1) Combining multiple simple operations like increments into a single optimized operation
2) Evaluating constant expressions at compile-time rather than run-time
3) Eliminating redundant computations and storing values in registers rather than memory when possible
4) Optimizing loops, conditionals, and expressions to minimize computations
Compiler optimization aims to minimize program execution time, memory usage, and power consumption by transforming programs in various ways before producing executable code. Some key techniques include instruction combining, constant folding, common subexpression elimination, strength reduction, dead code elimination, and loop optimizations. This improves program efficiency and performance.

Lecture 16 17 code-generation
The document discusses code generation which involves mapping intermediate code to machine code. It describes three key issues in code generator design: instruction selection which determines the best machine instructions to use, register allocation which assigns variables to registers, and evaluation order which determines the order of instructions. The document outlines three algorithms for code generation that involve partitioning code into basic blocks, performing intra-block optimizations, and code selection and assignment.
History of programming
The document provides background information on programming languages and their history. It discusses early pioneers in computer programming such as Ada Lovelace, Herman Hollerith, and Konrad Zuse. It outlines the development of many popular modern programming languages such as Fortran, COBOL, BASIC, Pascal, C, C++, Java, PHP, JavaScript, Python, Ruby, and others, describing their key features and common uses. Ada Lovelace is noted as creating the first computer program in 1843 for Charles Babbage's analytical engine.
Run time administration
1. Static allocation assigns storage locations to data objects at compile time. Stack allocation uses a stack to dynamically allocate memory for procedure activations and local variables at runtime. Heap allocation allocates memory for dynamic data structures from a heap region at runtime.
2. Access to non-local names can use lexical scoping by following access links or displays, or dynamic scoping by searching the stack.
3. Blocks can be nested and treated as parameterless procedures, with memory allocated on the stack when entered and deallocated on exit.
4. The activation record stores information for a procedure execution, including local data, saved registers, parameters, return values, and links to enclosing activations.

Chapter#01 cc
This document provides an overview of compiler design and the different phases involved in compiling a program. It begins with defining a compiler as a program that translates code written in one programming language into another target language to be executed by a computer. The major phases of a compiler are then described as the analysis phase (front-end) which breaks down and analyzes the source code, and the synthesis phase (back-end) which generates the target code. Key phases in the front-end include lexical analysis, syntax analysis, and semantic analysis, while the back-end includes code optimization and code generation. Different types of compilers such as single-pass, two-pass, and multi-pass compilers are also introduced based on how many times

COMPILER CONSTRUCTION KU 1.pptx
This document provides an introduction to compilers and their construction. It defines a compiler as a program that translates a source program into target machine code. The compilation process involves several phases including lexical analysis, syntax analysis, semantic analysis, code optimization, and code generation. An interpreter directly executes source code without compilation. The document also discusses compiler tools and intermediate representations used in the compilation process.
How a Compiler Works ?
A compiler works in several stages to translate a program from a source language to an output language. It performs lexical analysis to break the source code into tokens, syntactical analysis to check syntax is correct, semantic analysis to ensure code makes logical sense, and optionally generates intermediate code before final code generation and optimization to produce the target program.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
