OS-9 Ultra C/C++ Compiler

Microware¦s Ultra C/C++ is an advanced technology compiler for the OS-9 Real-time Operating System. Ultra C/C++ incorporates a revolutionary compiler design with state-of-the-art optimization techniques to extract maximum performance from modern 16-, 32-, and 64-bit CISC and RISC microprocessors.
Unlike traditional compilers that translate source code into microprocessor-specific assembly language, Ultra C/C++¦s front end modules compile source code into an intermediate code (I-code) format that is independent of the source language and target microprocessor.
The I-code representation of the program can then be linked against C/C++, OS and User libraries to generate an I-code image of the entire application. This file is processed by an I-code optimizer which performs various optimizations as specified by the user.
In the last stages of compilation, Ultra C/C++¦s back end modules translate the optimized I-code file into assembly language for the target Intel Architecture microprocessor. This code is further optimized, assembled, and linked into an executable module.
Linking and optimizing at the I-code level allows Ultra C/C++ to perform true inter-procedural optimization over the entire application, resulting in much faster and typically smaller executables.
Ultra C/C++ contains a single, non-transferable object code copy of the Ultra C/C++ Compiler system modules, support libraries, documentation and 90-day "Hotline" support.
