COFFThe Portable Executable PE format is a file format for executables, object code, DLLs, FON Font files, and others used in 3. Windowsoperating systems. The PE format is a data structure that encapsulates the information necessary for the Windows OS loader to manage the wrapped executable code. This includes dynamic library references for linking, API export and import tables, resource management data and thread local storage TLS data. On NT operating systems, the PE format is used for EXE, DLL, SYS device driver, and other file types. The Extensible Firmware Interface EFI specification states that PE is the standard executable format in EFI environments. On Windows NT operating systems, PE currently supports the IA 3. IA 6. 4, x. 86 6. AMD6. 4Intel 6. 4, and ARMinstruction set architectures ISAs. Prior to Windows 2. Windows NT and thus PE supported the MIPS, Alpha, and Power. PC ISAs. Because PE is used on Windows CE, it continues to support several variants of the MIPS, ARM including Thumb, and Super.

The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. This work is licensed under a Creative Commons AttributionShareAlike 3.

Analogous formats to PE are ELF used in Linux and most other versions of Unix and Mach O used in mac. OS. HistoryeditMicrosoft migrated to the PE format with the introduction of the Windows NT 3. All later versions of Windows, including Windows 9. ME and the Win. 32s addition to Windows 3. The format has retained limited legacy support to bridge the gap between DOS based and NT systems. For example, PECOFF headers still include an MS DOS executable program, which is by default a stub that displays a message like This program cannot be run in DOS mode or similar, though it can be a full fledged DOS version of the program a later notable case being Windows 9. SE installer. 3 PE also continues to serve the changing Windows platform. Some extensions include the. NET PE format see below, a 6. PE3. 2 sometimes PE, and a specification for Windows CE. Technical detailsedit. Structure of a Portable Executable 3. A PE file consists of a number of headers and sections that tell the dynamic linker how to map the file into memory. An executable image consists of several different regions, each of which require different memory protection so the start of each section must be aligned to a page boundary. For instance, typically the. However, to avoid wasting space, the different sections are not page aligned on disk. Part of the job of the dynamic linker is to map each section to memory individually and assign the correct permissions to the resulting regions, according to the instructions found in the headers. Import TableeditOne section of note is the import address table IAT, which is used as a lookup table when the application is calling a function in a different module. It can be in the form of both import by ordinal and import by name. Because a compiled program cannot know the memory location of the libraries it depends upon, an indirect jump is required whenever an API call is made. As the dynamic linker loads modules and joins them together, it writes actual addresses into the IAT slots, so that they point to the memory locations of the corresponding library functions. Though this adds an extra jump over the cost of an intra module call resulting in a performance penalty, it provides a key benefit The number of memory pages that need to be copy on write changed by the loader is minimized, saving memory and disk IO time. If the compiler knows ahead of time that a call will be inter module via a dllimport attribute it can produce more optimized code that simply results in an indirect call opcode. RelocationseditThis section needs to be updated. In particular Use of ASLR and the trickery used to dodge the resulting problems. Please update this article to reflect recent events or newly available information. October 2. PE files normally do not contain position independent code. Instead they are compiled to a preferred base address, and all addresses emitted by the compilerlinker are fixed ahead of time. In Lifehackers new video series, Day 1, were tackling exactly what its like to be a newbie in a variety of possiblyintimidating situations, starting off. If a PE file cannot be loaded at its preferred address because its already taken by something else, the operating system will rebase it. This involves recalculating every absolute address and modifying the code to use the new values. The loader does this by comparing the preferred and actual load addresses, and calculating a delta value. This is then added to the preferred address to come up with the new address of the memory location. Base relocations are stored in a list and added, as needed, to an existing memory location. 9Th Wonder Drum Kit here.

It also slows down loading of the module significantly. For this reason rebasing is to be avoided wherever possible, and the DLLs shipped by Microsoft have base addresses pre computed so as not to overlap. In the no rebase case PE therefore has the advantage of very efficient code, but in the presence of rebasing the memory usage hit can be expensive. This contrasts with ELF which uses fully position independent code and a global offset table, which trades off execution time against memory usage in favor of the latter. NET, metadata, and the PE formateditIn a. NET executable, the PE code section contains a stub that invokes the CLR virtual machine startup entry, Cor. Exe. Main or Cor. Dll. Main in mscoree. Visual Basic executables. The virtual machine then makes use of. NET metadata present, the root of which, IMAGECOR2. HEADER also called CLR header is pointed to by IMAGEDIRECTORYENTRYCOMHEADER6 entry in the PE headers data directory. IMAGECOR2. 0HEADER strongly resembles PEs optional header, essentially playing its role for the CLR loader. The CLR related data, including the root structure itself, is typically contained in the common code section,. It is composed of a few directories metadata, embedded resources, strong names and a few for native code interoperability. Metadata directory is a set of tables that list all the distinct. NET entities in the assembly, including types, methods, fields, constants, events, as well as references between them and to other assemblies. Use on other operating systemseditThe PE format is also used by React. OS, as React. OS is intended to be binary compatible with Windows. It has also historically been used by a number of other operating systems, including Sky. OS and Be. OS R3. However, both Sky. OS and Be. OS eventually moved to ELF. As the Mono development platform intends to be binary compatible with Microsoft. NET, it uses the same PE format as the Microsoft implementation. On x. 86, Unix like operating systems, some Windows binaries in PE format can be executed with Wine. The HX DOS Extender also uses the PE format for native DOS 3. Windows binaries in DOS, thus acting like an equivalent of Wine for DOS. On IA 3. 2 and x. Linux one can run Windows DLLs under loadlibrary. Mac OS X 1. PE files, but is not binary compatible with Windows. UEFI and EFI firmware use Portable Executable files for applications, as well as the Windows ABI. See alsoeditReferenceseditExternal linksedit.
