Conditional Instructions in Programming

A reference to a specific section or page in a book.

A list of all the topics covered in a book with page numbers for easy reference.

Unique identification numbers assigned to books to differentiate them.

Information about who owns the rights to a book, allowing others to use it with permission.

When a book is released to the public for sale.

The process of examining a book for accuracy and quality before it is published.

A comprehensive guide containing all instructions for a specific architecture, including their syntax, behavior, and potential usage.

The process of analyzing and understanding the structure and functionality of software, often to discover vulnerabilities or identify the original source code.

Techniques used to prevent or mitigate attacks by exploiting vulnerabilities in software or hardware.

Processes and techniques used to discover and exploit vulnerabilities in software or hardware, often for malicious purposes.

A set of instructions or commands that a computer processor can understand and execute.

The core logic of a computer system that controls the execution of instructions and manages data flow.

A specific type of instruction used in a computer's instruction set, often with a specific function or purpose.

The standard format or structure used to represent and write instructions in a particular architecture.

A situation where the result of an arithmetic operation exceeds the maximum value that can be stored in the designated data type. For example, adding two large unsigned integers might result in a sum that is too big to fit within the allocated memory space.

Special bits that record the result of an arithmetic or logical operation. They provide information about the outcome, such as whether the result is zero, negative, or if there was a carry or borrow.

Instructions that execute different code blocks based on the status of the condition codes. They provide a way to control the flow of execution based on the outcome of previous operations.

An instruction in the Thumb instruction set that executes a block of code only if the condition codes meet a specific criteria. It's a way to implement simple if-then logic.

Instructions that are designed to set specific condition codes based on the outcome of an operation. They provide a way to signal the state of the result without directly modifying the data.

A suffix added to certain instructions to indicate that they should also update specific condition codes based on the result of the operation. This allows for conditional execution based on the outcome of the instruction.

The 'S' suffix, when added to add and subtract instructions, sets the condition codes based on the result of the operation. This allows for conditional execution based on the addition or subtraction outcome.

The 'S' suffix, when added to logical shift instructions, updates the condition codes based on the outcome of the shift. This helps determine if the result is zero, negative, or carries a flag.

A sequence of characters used to represent text in a program. In this context, it refers to a sequence of characters enclosed in double quotes.

A file extension commonly used for assembly code files.

A program that translates assembly code into machine-readable instructions (object code).

A register used to store the system call number.

A technique for invoking a system call in Arm architecture.

A collection of tables that describes how to load and run the program, containing information for the operating system and loader.

A collection of tables describing global attributes of the program, such as the architecture, program entry point, and pointers to other tables.

Contains information about the program's logical sections, how to load them into memory, and their size.

Describes how to execute the ELF program, including how to load segments into memory and their size.

The function that bootstraps the program, runs global C++ constructors, and calls the program’s main function.

A library that provides functions like printf and exit for interacting with the system.

A file that contains the startup code that initializes the program before calling the main function.

A file that handles the cleanup process after the main function returns, and the exit of the program.

A 16-byte sequence that identifies an ELF file. It starts with 0x7f followed by "ELF" in ASCII.

Indicates whether the ELF file uses the 32-bit or 64-bit format. Generally, 32-bit programs use the 32-bit format and 64-bit programs use the 64-bit format.

Specifies the byte order (big-endian or little-endian) for interpreting data within the ELF file. Arm systems typically use little-endian.

Indicates the version of the ELF file format being used. Currently, version 1 is prevalent.

Tells the loader what type of processor the ELF file is designed for. For example, AArch64 for 64-bit Arm processors and ARM for 32-bit Arm processors.

Provides extra information specific to the targeted architecture. This field can hold various flags.

A field that stores additional information about the ELF file, such as the architecture-specific flags, which might be used by the loader. This field helps in customizing interactions between the ELF file and the loader.

This field tells the loader what kind of target machine the ELF file is intended for. It specifies the processor architecture, which is vital for loading and executing the program correctly.
