PentiumGCC is a branch of GCC (the GNU Compiler Collection, formerly known as gcc/egcs) especially designed to optimize for x86 compatible chips. Speed improvements of 2-30% are possible. MMX support for P-II is being worked on. Since PentiumGCC is distributed as a patch to GCC, you will need to get the source code for the main GCC distribution to compile PentiumGCC.
zJSP is an experimental translator from JavaServer Pages (jsp's) to Java. It is designed to be used in conjunction with Sun's Java Servlet Developers Kit (JSDK), version 2.0. It *should* work with any Java Servlet environment compatible with JSDK servlets. zJSP is implemented as a page compiler, translating JSP pages into Java Servlets, which are then run using a Java Servlet environment.
Sather is an object oriented language designed to be simple, efficient, safe, flexible and non-proprietary. One way of placing it in the "space of languages" is to say that it aims to be as efficient as C, C++, or Fortran, as elegant as and safer than Eiffel, and support higher-order functions and iteration abstraction as well as Common Lisp, CLU or Scheme.
The GRASP Project has created an algorithmic-level graphical representation for software called the Control Structure Diagram (CSD). The CSD was created to improve the comprehension efficiency of Ada source code and, as a result, improve software reliability and reduce software costs. Since its creation, the CSD has been expanded and adapted to include other languages. GRASP provides the capability to generate CSD's from Ada 95, C, C++, Java, and VHDL source code in both a reverse and forward engineering mode with a level of flexibility suitable for professional application. GRASP has been integrated with the GNU family of compilers for Ada (GNAT) and C (gcc), and Sun's javac compiler for Java. Use of GRASP is not restricted to these compilers, however. This has resulted in a comprehensive graphically-based development environment for these languages. The user may view, edit, print, and compile source code as CSDs with no discernible addition to storage or computational overhead.
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.
