> It should be a 2D slice/plane embedded into a 3D space. I was able to come up with the plot, attached. My intention was to plot national boundaries on the surface of a sphere. And put the slice inside. However, I haven't (as yet) worked out how to get the coordinates for the boundaries. Let me know, if of any value. And I'll post the code. (But needs to be polished first)

Thanks for your idea. It should be a 2D slice/plane embedded into a 3D space. Could be static, I just need to make a single figure from it for illustration of the Earth together with its interior in 3D. So, the interior would be a slice in 2D along a fixed longitude. And along this 2D slice would be a heatmap. Again, embedded in 3D, since it would be shown as a slice of Earth in 3D. Duncan?s

Hi Everyone！ I am a newbie at llvm. So the question may be fundamental but difficult to me. I want to add an trinsics in x86 and make the following changes.I want that max_qb can find the max of two Integers and return it. In src/include/llvm/IR/Intrinsics.td : let TargetPrefix = "x86" in { def int_x86_max_qb: GCCBuiltin<"__builtin_x86_max_qb">,

I agree, that doesn't look right.

I'm working on debugging AVX shuffles and I ran into an interesting problem. The current isSHUFPMask predicate in X86ISelLowering needs to be generalized to operate on 128-bit or 256-bit masks. There are probably lots of other things to change too (LowerVECTOR_SHUFFLE_4wide, etc.) but I'll worry about that later. The generalized rule is: 1. For the low 64 bits of the result vector, the

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it?
