<p>This work presents an approach to code generation for a new 64-bit ExplicitlyParallel Instruction Computing (EPIC) architecture from Intel, called IA-64. Themajor contribution of this work is the design of a machine independent optimizer,munger, that transforms code generated originally for a Very Long Instruction Word(VLIW) processor, called Tinker, to one that can run on the IA-64 architecture.The munger does this transformation by reading in a set of rules that specify amapping from Tinker specific code to IA-64 specic code. Th aim is to do thistransformation outside the compiler back-end, thereby being able to take advantageof any optimizations that the back-end might perform on the code. This would alsopreclude rewriting the existing back-end significantly, to support the new architecture.The primary motivation for this approach was the fairly large similarity betweenthe Tinker, and the IA-64 architectures. Besides, Tinker is an experimental VLIWarchitecture that supports a number of features to exploit instruction level parallelism(ILP) and can be easily extended to support new features. This makes the back-endfor Tinker an ideal compiler to retarget for the IA-64 architecture, since it alreadyperforms most ILP optimizations that are supported on the IA-64.<P>
