llvm dev - Aug 2013 - [LLVMdev] Lower ConstantExprs into instructions

Hello,

I found an out-of-date ConstantExpressionsLower pass in llvm-1.5, it
was removed in later versions.
Is there any existing similar pass which converts all constant
expressions into instructions for recent releases (e.g. 3.1 or above)
?

Thanks
