strings - print the sequences of printable characters in files.
For each file given, GNU strings prints the printable character sequences that are at least 4 characters long (or the number given with the options below) and are followed by an unprintable character.
strings is mainly useful for determining the contents of non-text files.
objdump is the mother of all binary tools.
readelf subsumes the functionality of size and nm.
objcopy contains most of the functionality of strip.
DWARF is a widely used, standardized debugging data format. It was originally designed along with Executable and Linkable Format (ELF).
The compilation is the process of converting the source code of the C language into machine code. As C is a mid-level language, it needs a compiler to convert it into an executable code so that the program can be run on our machine.
In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program.
In C and C++ programming language terminology, a translation unit (or more casually a compilation unit) is the ultimate input to a C or C++ compiler from which an object file is generated. A translation unit roughly consists of a source file after it has been processed by the C preprocessor, meaning that header files listed in #include directives are literally included, sections of code within #ifndef may be included, and macros have been expanded.
The Executable and Linkable Format (ELF), is a common standard file format for executable files, object code, shared libraries, and core dumps.
Directives are used mainly to define symbols, allocate storage, and control the behavior of the assembler. Directives allow the programmer to control how the assembler does its job.
Previously, we've introduced the basic concepts associated with AAPCS (AArch64 Procedure Call Standard).
In this article we'll have a closer look at the ARM64 PCS, with demonstrations of the call conventions and stack layout.
In this article we'll introduce the basic concepts of AAPCS (AArch64 PCS), including program flow, function/subroutine and the Procedure Call Standard.
In this article, we'll explore ARM program flow based on conditional execution.
In this article, we'll explore the stack modes, activities and accesses in ARM(A32/A64).
