Hi, I need to fetch lower and higher 32bits from 64bit value. I found "CreateLShr" function to fetch lower 32bits, llvm::Value *intermediateValue = LLVMIRBuilder->CreateLShr(x64BitValue, 32); What function I need to use for fetching upper 32bits from 64bit value.

Oh, no. I should have been more clear. The patch was not rejected, just lost in the daily shuffle. I already have my employer's approval to send this upstream, so I will prepare a patch against trunk this morning. > I proposed a similar patch to LLVM (left circular shift) around 10/2011. > > Parts of my patch did make it into trunk about a year after, but others > > did not.
