<DIV><FONT face=Verdana color=#000080 size=2>Well, I want to do some experiments
about the compiler optimization in llvm under SPM and I need performance
evaluation. As I know, alpha is a general-purpose CPU, so I consider that
arm may be an alternative. S</FONT><FONT face=Verdana
color=#000080 size=2>implesim-arm is able to do performance simulation
while m5-arm is still under development. Then, what should I do? Do the
experiment under m5-alpha or use simplesim-arm? And if I choose to use m5-alpha,
can I use llvm as the compiler for this simulator?</FONT></DIV>

<DIV>IMNSHO, don't use SimpleScalar. It's simulation model is WAY ourt of date.</DIV>

<DIV>Use M5 instead:</DIV>
