...ke them easier for target-independent code > to understand. Yes, I have tried to do that as much as possible. There are still a number of operations where we've ended up using intrinsics, for varying reasons. For example, I had been planning to have the front-end translate the VTRN, VZIP, and VUZP builtins to vector shuffles, since that is exactly what they are. But, after discussing it with Evan, I changed these to intrinsics because we couldn't figure out a good way to handle them as shuffles. They take two vector operands and shuffle them in place, producing two ve...

Hi, In R command line, when I type "help(something)", it will always show the help in the different mode such that I don't see command lines anymore but just the help document. If I quit from the help mode, I will only see the command lines by not the help document. I would like the help document and command lines be show in the same mode. I'm wondering how to do so. Regards,

Hello, WRE contains the following information about the "exec" subdirectory of a package : "Subdirectory exec could contain additional executables the package needs, typically scripts for interpreters such as the shell, Perl, or Tcl. This mechanism is currently used only by a very few packages, and still experimental." I think it would be useful to expand "very

Hi Bob, An alternative would be to model the operations as regular shuffle, load, and store operators, combined to describe the actual instructions. This would make them easier for target-independent code to understand.

I'm trying to move from Matlab to R, and I'm stuck even getting started. This sounds to me like the dumbest question in the world but... how does one put R source code in files? Over the last three days I've gone front to back through the Introduction to R and the R Language Definition, and while I'm excited that the language is so Lispish, none of what I read described how to

The ARM Neon load, store and shuffle operations that I've been implementing recently with LLVM intrinsics do not care about the distinction between vectors with i32 and f32 elements -- only the size matters. But, because we have only MVT::fAny and MVT::iAny types, I've been having to define separate intrinsics for the operations with floating-point vector elements. It

Quick informal poll: what is everyone's favorite text editor for working with R? I'd like to hear from people who are using editors that have some level of direct R interface (e.g. Tinn-R, Komodo+SciViews). Thanks! --j -- Jonathan A.
