Eliminating branches using a superoptimizer and the GNU C compiler

In VLIW (Very Long Instruction Word) compiler, one of the most important issue is how to handle conditional branches, because control dependences are caused by conditional branches and limit the scope of scheduling.This paper proposes the efficient ...

In an attempt to reduce the number of operand memory references, many RISC machines have thirty-two or more general-purpose registers (e.g., MIPS, ARM, Spectrum, 88K). Without special compiler optimizations, such as inlining or interprocedural register ...

Dynamic branch prediction plays a key role in delivering high performance in the modern microprocessors. The cycles between the prediction of a branch and its execution constitute the branch misprediction penalty because a misprediction can be detected ...
