enableJIT() and internal R completions (was: [ESS-bugs] ess-mode 12.03; ess hangs emacs)
Hello, JIT compiler interferes with internal R completions: compiler::enableJIT(2) utils:::functionArgs("density", '') gives: utils:::functionArgs("density", '') Note: no visible global function definition for 'bw.nrd0' Note: no visible global function definition for 'bw.nrd' Note: no visible global function definition for 'bw.ucv'

[LLVMdev] Multimedia IO instructions & partial backend implementations for simple CPUs
...atform's system libraries and how to link to them and such; > LLVM doesn't paper over this. OK. So to be specific, I am using a Haskell language binding to LLVM, not C. With my multimedia IO examples, am I correct in thinking I have a few options: 1. Do IO in my host language, and parse bytestrings in to LLVM data structures, e.g. vectors. Then, pass these data structures to LLVM generated code for JIT compilation. 2. Write IO functions in C, and compile with -emit-llvm . Then in my LLVM code generation, I read this external function from a bitcode file generated by clang. Here, there is no I...

[LLVMdev] Multimedia IO instructions & partial backend implementations for simple CPUs
Hi, I'm getting started with LLVM, with the intention of writing a DSL that compiles to LLVM IR, to target a new CPU instruction set. I have two questions: 1. Multimedia IO in LLVM In the paper "The LLVM Instruction Set and Compilation Strategy" [1], there is talk about a possible multimedia instruction set in a future LLVM release: "Note that LLVM is a virtual instruction

Converting numbers to and from raw
How can I convert an integer or double to and from their internal representation as raws of length 4 and 8? The following works for positive integers (including those represented as floats): # Convert integer (represented as integer or double) to sequence # of raw bytes, least-significant byte first. # intToRaw(0) => raw(0) # intToRaw(17^9) => 91 64 63 9c 1b # intToRaw(2^60/3) => 40 55

HOgg 0.2.0 Released
HOgg 0.2.0 Released ------------------- The HOgg package provides a commandline tool for manipulating Ogg files, and a corresponding Haskell library. http://snapper.kfish.org/~conrad/software/hogg/ This is the initial public release. The focus is on correctness of Ogg parsing and production. The capabilities of the hogg commandline tool are roughly on par with those of the oggz* tools[0],
