Proteus Cross Compiler
Proteus Cross Compiler is a system that allows the generation of Java
executables from C/C++ and fortran code.
LLVM compilation system (e.g. Clang or llvm-gcc/g++/gfortran) can be used to
generate LLVM intermediate representation and apply various optimisations to
this output. This output can then be passed to Proteus to generate Java(tm)
source code and ultimately java executables. It provides implementation of some
but not all C, C++ and Fortran runtime libraries.
Proteus has been written with a view to producing Java executables that run with
comparable performance to the native code. Acheiving upto 50% of native speed
without intervention. Proteus provides a simple ability to provide alternative
implementations of any function and this feature has been used to increase
performance to 85% of native speed (running on 64bit linux).
