OS 2200 provides a complete Java environment. [12] Java on OS 2200 has evolved from an interesting additional capability for small servlets and tools to a full environment capable of handling large applications. The Virtual Machine for the Java Platform on ClearPath OS 2200 JProcessor is a Linux port of the Oracle Corporation Java release.
In addition to the binary application code, the executables may contain headers and tables with relocation and fixup information as well as various kinds of meta data. Among those formats listed, the ones in most common use are PE (on Microsoft Windows), ELF (on Linux and most other versions of Unix), Mach-O (on macOS and iOS) and MZ (on DOS).
The base of each is exec (execute), followed by one or more letters: e – An array of pointers to environment variables is explicitly passed to the new process image. l – Command-line arguments are passed individually (a list) to the function. p – Uses the PATH environment variable to find the file named in the file argument to be executed.
This environment may address a number of issues including the management of application memory, how the program accesses variables, mechanisms for passing parameters between procedures, interfacing with the operating system, and otherwise. The compiler makes assumptions depending on the specific runtime system to generate correct code ...
The GCJ Java compiler can target either a native machine language architecture or the Java virtual machine's Java bytecode. [82] When retargeting GCC to a new platform, bootstrapping is often used. Motorola 68000, Zilog Z80, and other processors are also targeted in the GCC versions developed for various Texas Instruments, Hewlett Packard ...
A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. For example, a compiler that runs on a PC but generates code that runs on Android devices is a cross compiler. A cross compiler is useful to compile code for multiple platforms from one development host.

On 13 November 2006, Sun's HotSpot Java virtual machine (JVM) and Java Development Kit (JDK) were made available [4] under the GPL license. [5]Since version 0.95, GNU Classpath, a free implementation of the Java Class Library, supports compiling and running javac using the Classpath runtime — GNU Interpreter for Java (GIJ) — and compiler — GNU Compiler for Java (GCJ) — and also allows ...
