...g wrong, but should be looked at in conjunction with all the other factors such as what the pass is trying to achieve optimization-wise, etc etc. That is to say, it's not necessarily a bug, but it can be (especially when observed as a regression between compiler revisions). Using the standard Fibonacci example with clang and lldb from this afternoon: 1 #ifdef _MSC_VER 2 # define DEX_NOINLINE __declspec(noinline) 3 #else 4 # define DEX_NOINLINE __attribute__((__noinline__)) 5 #endif 6 7 DEX_NOINLINE 8 void Fibonacci(int terms, int& total) 9 { 10 int first = 0; 11 int second = 1;...

Introduction ============ `SROA' is an early stage pass running at the very beginning of the pipeline in `-O{1,2,3}'. Greg Bedwell's report from his DExTer tool shows SROA on function as one of the major culprits of Debug Info loss. With debugify-each partially done I tried testing this on the amalgamated sqlite source. The steps are as follows: ,---- | # generate

To try and be a bit more helpful there's definitely something dodgy happening to variable visibility on the fibonacci example in LICM. With "BISECT: NOT running pass (32) Loop Invariant Code Motion on loop": ## BEGIN ## [1, "main", "tests/fibonacci/test.cpp", 24, 6, "BREAKPOINT", "FUNC", {}] [2, "main", "tests/fibonacci/test.cpp", 25, 2, &quot...

Hi! I am trying to work out the code to get a Fibonacci sequence, using the while() loop and only one variable. And I can't figure it out. Fibonacci<-c(1,1) while (max(Fibonacci)<500){ Fibonacci<-c(Fibonacci, (max(Fibonacci) + ?(Fibanacci))) } How can I tell R to take the value one before the max value? (Without defining another variable...

Hola LLVMers, I'm getting a crash when using ConstantFP::get. I can repro it by adding one line to the Fibonacci example program: int main(int argc, char **argv) { int n = argc > 1 ? atol(argv[1]) : 24; // Create some module to put our function into it. Module *M = new Module("test"); // We are about to create the "fib" function: Function *FibF = CreateFibFuncti...

Dear all, I have an implementation of streams in R. The current implementation of delay() and force() is inspired from the LISP implementation found in Part VI "Languages for AI problem solving" of "Artificial Intelligence" by G. Luger. I have tested it with the Fibonacci example in the same book (see examples below). It works but I do run into a problem when I try to generate fibonacci series more than 25 elements. > accumulate.into.list(25,fibonacci.stream(0,1)) Error in cons.stream(fibonacci1 + fibonacci2, fibonacci.stream(fibonacci2, : evaluation is ne...

We have been using LLVM 3.4 and are currently migrating to LLVM 3.8.1. We have been using the Old JIT and since it has been removed since 3.6, we have to use MCJIT. I find that run-time performance is very poor in 3.8.1 for the Fibonacci example in llvm/examples/fibonacci.cpp. Logs below for fib34 and fib381 for input values of 30 and 40. I first thought it could be that MCJIT compile time is slower, but as I increase the input value, fib381 gets slower and slower in run-time performance (almost 200X for an input value of 40). Any...

...n LLVM (and linux, and gcc and so on) and I'd like to know how to run and test LLVM projects. I've downloaded, installed and tested LLVM tools, such as llvm-gcc, llc, lli etc. But I don't know how to test examples provided. I just called "sudo make" inside "llvm/examples/fibonacci/", what generated a directory named "Release" containing 2 files: *fibonacci.d* and * fibonacci.o*. How can I generate a binary executable file from those ones? I've tried to use gcc, but I got a lot of undefined reference errors. Where can I find a example of the command line I...

Hi, I'm learning Fortran and trying to load a Fortran subroutine into R. I've done: R SHLIB Fibonacci.f and it compiled fine. Then I went into R and done: > dyn.load("Fibonacci.so") > Fib <- function(n) { + .Fortran("Fibonacci", + as.integer(n))[[1]] + } > Fib(5) Error in .Fortran("Fibonacci", as.integer(n)) : C/Fortran function...

Hello Apparently the file llvm/examples/Fibonacci/fibonacci.cpp generate JIT code without explicitly doing any pass (but I suppose that internally, compiler passes are running!) - is there a dissymetry between JIT machine code generation in memory, and C or ELF shared object generation in files? I thought that all these shared a lot of LLVM infras...

Hello everybody, Could someone please send me a very simple example using Fortran from R? Say pass a value to an executable and get the result in R. Actually it seems it may be possible to call an *.f file ?? or I am wrong again? The manual is very terse on the subject.
