This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.
shc is a shell script compiler for Unix-like operating systems written in the C programming language. The Shell Script Compiler (SHC) encodes and encrypts shell scripts into executable binaries. Compiling shell scripts into binaries provides protection against accidental changes and source code modification, and is a way of hiding shell script ...
ROSE: an open source compiler framework to generate source-to-source analyzers and translators for C/C++ and Fortran, developed at Lawrence Livermore National Laboratory MILEPOST GCC : interactive plugin-based open-source research compiler that combines the strength of GCC and the flexibility of the common Interactive Compilation Interface that ...
With roughly 15 million lines of code in 2019, GCC is one of the largest free programs in existence. [4] It has played an important role in the growth of free software, as both a tool and an example. When it was first released in 1987 by Richard Stallman, GCC 1.0 was named the GNU C Compiler since it only handled the C programming language. [1]
For example, Common Lisp can be compiled to Java bytecode (then interpreted by the Java virtual machine), C code (then compiled to native machine code), or directly to native code. Environments that support multiple compilation output languages provide developers control to choose either execution speed or cross-platform compatibility.
The ROSE compiler framework, developed at Lawrence Livermore National Laboratory (LLNL), is an open-source software compiler infrastructure to generate source-to-source analyzers and translators for multiple source languages including C (C89, C99, Unified Parallel C (UPC)), C++ (C++98, C++11), Fortran (77, 95, 2003), OpenMP, Java, Python, and PHP.
Once they had improved the compiler to the point where it could compile its own source code, it was self-hosting. [2] The compiler as it exists on the standard compiler tape is a machine language program that was obtained by having the S-expression definition of the compiler work on itself through the interpreter. —
In C#, compiler directives are called pre-processing directives. There are a number of different compiler directives including #pragma, which is specifically used to control compiler warnings and debugger checksums. [5] [6] The SQLite DBMS includes a PRAGMA directive that is used to introduce commands that are not compatible with other DBMS. [7]
