  • Using Ld the GNU Linker
    Using ld The GNU linker ld version 2 January 1994 Steve Chamberlain Cygnus Support Cygnus Support [email protected], [email protected] Using LD, the GNU linker Edited by Jeffrey Osier (jeff[email protected]) Copyright c 1991, 92, 93, 94, 95, 96, 97, 1998 Free Software Foundation, Inc. Permission is granted to make and distribute verbatim copies of this manual provided the copyright notice and this permission notice are preserved on all copies. Permission is granted to copy and distribute modified versions of this manual under the conditions for verbatim copying, provided also that the entire resulting derived work is distributed under the terms of a permission notice identical to this one. Permission is granted to copy and distribute translations of this manual into another lan- guage, under the above conditions for modified versions. Chapter 1: Overview 1 1 Overview ld combines a number of object and archive files, relocates their data and ties up symbol references. Usually the last step in compiling a program is to run ld. ld accepts Linker Command Language files written in a superset of AT&T’s Link Editor Command Language syntax, to provide explicit and total control over the linking process. This version of ld uses the general purpose BFD libraries to operate on object files. This allows ld to read, combine, and write object files in many different formats—for example, COFF or a.out. Different formats may be linked together to produce any available kind of object file. See Chapter 5 [BFD], page 47, for more information. Aside from its flexibility, the gnu linker is more helpful than other linkers in providing diagnostic information.

  • Linker Script Guide Emprog
    Linker Script Guide Emprog Emprog ThunderBench™ Linker Script Guide Version 1.2 ©May 2013 Page | 1 Linker Script Guide Emprog 1 - Linker Script guide 2 -Arm Specific Options Page | 2 Linker Script Guide Emprog 1 The Linker Scripts Every link is controlled by a linker script. This script is written in the linker command language. The main purpose of the linker script is to describe how the sections in the input files should be mapped into the output file, and to control the memory layout of the output file. Most linker scripts do nothing more than this. However, when necessary, the linker script can also direct the linker to perform many other operations, using the commands described below. The linker always uses a linker script. If you do not supply one yourself, the linker will use a default script that is compiled into the linker executable. You can use the ‘--verbose’ command line option to display the default linker script. Certain command line options, such as ‘-r’ or ‘-N’, will affect the default linker script. You may supply your own linker script by using the ‘-T’ command line option. When you do this, your linker script will replace the default linker script. You may also use linker scripts implicitly by naming them as input files to the linker, as though they were files to be linked. 1.1 Basic Linker Script Concepts We need to define some basic concepts and vocabulary in order to describe the linker script language. The linker combines input files into a single output file. The output file and each input file are in a special data format known as an object file format.

Uvedené jsou techniky ochrany před rozkladem či zkoumáním obsahu spustitelného souboru. Představené jsou příklady programů zabývajících se zpětným překladem. Dále se práce zaobírá architekturou procesoru s důrazem na mikroprocesory Intel a Motorola. Jsou ukázané rozdílné formáty spustitelných souborů. Byl implementovaný generický modulovatelný zpětný assembler.V tomto textu je představená jak jeho struktura, tak zásuvné moduly, které prezentují tři různé techniky disassemblovaní. Jeden z modulů používa vícevláknový parser, který je vlastním návrhem autora. Tyto přístupy jsou v závěru porovnané a je nastíněn další vývoj. Abstract This thesis describes procedures and tools of reverse engineering in terms of software development. There are introduces different techniques of protection against decomposition of executables. The work also mentions some programs used for decomposition analysis. Furthermore it contains information about architecture of processing units, with emphasis on microprocessors Intel and Motorola. Variety of executable formats is shown. Generic retargetable disassembler was implemented. There is a description of its structure and plugins. These plugins represents three algorithms used for disassembling a program.

  • Why Does My Program Not Link Or Not Execute Global Constructors
    Ns-3 Application Note Why Don’t Those #@(%!~& Libraries Work? Craig Dowell [email protected] Background Consider the following program int main(int argc, char **argv) { myprintf("Hello World\n"); } When you compile this program, the compiler determines that there is no function called myprintf in the compilation unit (the source file) and marks the function as an unresolved reference. When the executable is linked, the linker looks through its list of libraries looking for an implementation of the function myprintf. The linker handles providing an implementation in one of two ways depending on the kind of file providing the implementation. • If the implementation is found in a static library (e.g., libcore.a), the linker copies the implementation of myprintf into the executable. The linker must then recursively search for further unresolved references in the myprintf function and resolve them by (possibly) looking in other libraries. This continues until the executable contains all of the code required to execute myprintf (there are no unresolved references). • If the implementation of myprintf is found in a dynamic library (e.g., libcore.so), the linker adds a note to itself that the unresolved reference can be resolved by loading the dynamic library. The linker recursively searches for further unresolved references and continues until all references are resolved. What happens when you run the resulting program depends on the kind of library to which you linked. • If you linked to static libraries, your program is self-contained. It will be loaded into memory and executed, starting at a system-dependent entry point.
