If all 8086 segments were set to be identical in such an EXE file (i.e. the "tiny" memory model was used), then exe2bin could convert it to a COM file. [3] exe2bin could also be used to convert compiled code to make it suitable to be embedded in ROM as part of BIOS or a device driver.
Before then, py2exe was made only for Python 2, [4] and it was necessary to use an alternative like cx_Freeze for Python 3 code. Although this program transforms a .py file to an .exe, it does not make it run faster because py2exe bundles the Python bytecode without converting it to machine-code.
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
It is the standard format for executables on Windows NT-based systems, including files such as .exe, .dll, .sys (for system drivers), and .mui. At its core, the PE format is a structured data container that gives the Windows operating system loader everything it needs to properly manage the executable code it contains.
convert is an external command first introduced with Windows 2000. [2] If the drive cannot be locked (for example, the drive is the system volume or the current drive) the command gives the option to convert the drive the next time the computer is restarted.
Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter.Unlike human-readable [1] source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of ...

When code generation occurs at runtime, as in just-in-time compilation (JIT), it is important that the entire process be efficient with respect to space and time. For example, when regular expressions are interpreted and used to generate code at runtime, a non-deterministic finite-state machine is often generated instead of a deterministic one, because usually the former can be created more ...
