...of these as they seem to be temporary. Dan Gohman on IRC let me know these are used by a closed source OpenCL backend, and I imagine that at some stage the OpenCL backend could migrate to the standard conversion instructions. This is what I propose: Add a "round" flag to FPToUIInst and FPToSIInst. The absence of this flag means truncation is needed whereas presence indicates rounding. The SelectionDAG for FP_TO_UINT and FP_TO_SINT are extended to add an immediate that indicates whether rounding is needed. To legalise a rounding FP_TO_UINT or FP_TO_SINT we use the technique described in [...

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.
