The Free Pascal Compiler is a Turbo Pascal 7.0 and Delphi-compatible 32/64 bit Pascal Compiler. It comes with a fully TP 7.0-compatible run-time library. Some extensions have been added to the language, like function overloading. Shared libraries can be linked. Basic Delphi support is implemented with classes, exceptions, RTTI, and ansistrings. A Free Component Library (FCL) is available with the base classes. Bindings for X11, ncurses, GTK, OpenGL, zlib, mysql, interbase and postgres are available.
lcc is a retargetable compiler for ISO Standard C. It generates code for the ALPHA, SPARC, MIPS R3000, and Intel x86 and its successors. Despite the fact that any Linux system will already have gcc, there are reasons for installing lcc as well. lcc is small, compiles more quickly than gcc, and helps prevent some porting bugs. It also gives more useful error messages in some circumstances. This means that it is sensible to use lcc during development, and gcc for the final binary where you want the better optimization.
Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments. It may also be used as a batch-oriented language.
Excelsior JET is a Java VM enhanced with an Ahead-Of-Time (AOT) compiler and deployment toolkit. It is certified Java Compatible on Windows and Linux on Intel x86 hardware. The 64-bit version is in the works. Excelsior JET Optimizer transforms your classes and JARs into high-performance binary executables. Excelsior JET Runtime includes a licensed Sun implementation of the Java API and Excelsior's proprietary JVM, which is responsible for Java memory management, threading, synchronization, security, and JIT compilation of classes that could not be precompiled. The Excelsior JET Installation Toolkit makes it possible to prepare your optimized application for deployment to end-user systems.
Critical Mass Modula-3 is an easy-to-use and easy-to-install Modula-3 system that contains considerable enhancements over its ancestor DEC SRC Modula-3, including modules loadable at runtime, implicit exceptions (even for checked runtime and gc failures), COM-compatible object layout (for Win32), Unicode support, and 64-bit support for 64-bit machines.
SUIF (Stanford University Intermediate Format) is an infrastructure designed to support collaborative research in optimizing and parallelizing compilers. SUIF1 includes a SUIF-to-Fortran backend, a graphical browser, a parallelization system, and a call-graph library. SUIF2 includes Java and C frontends, object-oriented extensions, and an intraprocedural dataflow framework.
OpenC++ is a source code translation tool for C++. Programmers can easily implement various kinds of translation so that they can define new syntax, new annotation, and new object behavior. OpenC++ is useful if they need to, for example, develop extensions to C++, add domain-, application-, or class-specific compiler optimizations, or build their own version of (runtime) MOP for C++.
