  author={Noah Snavely and Saumya Debray and Gregory Andrews},
EPIC architectures, such as the Intel IA-64 (Itanium), comb ine explicit instruction-level parallelism with instruction pr edication. To generate efficient code, it is important to use predication e ffectively. In particular, it is important to replace conditional branc hes and multiple code blocks by single, branch-free code blocks whe n doing so would lead to faster code. This process, which is known as if-conversion, is generally carried out early in the code-g eneration process; hence… CONTINUE READING
