Hi all. Using the following code: plot(bsa, abs, col='blue', pch=16, xlim=c(0, 25), ylim=c(0.0, 1.0), xlab = expression(paste(BSA, " (", mu, "g)", sep="")), ylab=expression(A[595])) plot(unknown1, abs2, col='blue', pch=16, xlim=c(0, 25), ylim=c(0.0, 1.0), xlab = expression(paste(Unknown_1, " (", mu, "g)", sep="")), ylab=expression(A[595])) plot(unknown2, abs3, col='blue', pch=16, xlim=c(0, 25), ylim=c(0.0, 1.0), xlab = expression(paste(Unknown_2, &qu...

Hello LLVM, A recent commit creates the isIntDivCheap() target query. http://reviews.llvm.org/D12082 The current approach has a couple shortcomings. First, when targets decide divide is cheap, the DAGCombiner ignores obvious power-of-2 optimizations. In the targets I know, shifts are cheaper than divides in both speed and size. The target cannot see the value in the isIntDivCheap() call, so
