In effect, C is being used as a portable compiler target language. It offers a simple and effective way of avoiding the need to re-implement effective register allocation, instruction selection, and instruction scheduling, and so on, all for a variety of target architectures. The trouble is that C was designed as a programming language not as a compiler target language, and is not very suitable for the latter purpose. The obvious thing to do is to define a language that is designed as a portable target language. This describes C\u2013, a portable compiler target language, or assembler. C\u2013 has to strike a balance between being high-level enough to allow the back end a fair crack of the whip, while being low level enough to give the front end the control it needs. It is not clear that a path exists between these two rocks; the ghost of UNCOL lurks ominously in the shadows. Yet the increasing popularity of C as a compiler target language (despite its unsuitability) suggests strong demand, and provides an existence proof that something useful can be done.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Of late it has become very common for resarch compilerrs to emit C as their target code, relying on a C compiler to generate machine code.
