Proteus Cross Compiler system allows the generation and compilation of Java Code from llvm-gcc compatible languages (C/C++/fortran). The generated code will execute at up to 50% of native code.
...It provides a set of classes and overloaded operators that allow the programmer to define regular path expressions over user-defined data structures using solely the GCCcompiler
An object-oriented language that compiles to native code, for POSIX and Windows systems. Requires Expat, GCC, as well as MinGW/Msys for Windows. Compiler generates C++ code but manages various tasks that C++ leaves to programmers, provides interfaces, gc
A cross-platform, cross-compiler, cross-CPU C header library for programming with SIMD instruction sets. X86 (MMX/SSE/SSE2) GCC and MSVC, PPC Altivec GCC, WMMX ARM GCC, and software emulated SIMD are supported.
LLVM is a unique compiler infrastructure designed for the optimization of programs from arbitrary programming languages. Compilation in C and C++ programs is supported using a parser based on GCC 3.4. Backends exist for X86, Sparc, PowerPC and "C".
