[LLVMdev] Code compiling in gcc but not llvm
Hi,
This is my first post, sorry if not in the right format.
I am stuck at a place where I have a code fragment that runs in normal gcc
but fails when I give -fplugin=dragonegg.so
extern int *testfunc();
extern __typeof (testfunc) testfunc __asm__ ("" "__GI_testfunc")
__attribute__ ((visibility ("hidden")));
extern __typeof(testfunc) __testfunc;

[LLVMdev] Question about "const"
Hi all. I have a next problem. I need to implement some object that will work with both const and "constless" object: Instruction* and const Instruction*, for example.
How to implement it better?
Currently I see two possible ways:
1. Templates.
template <class InstructionTy>
class InstructionProcessorT {
InstructionTy *Inst;
InstructionProcessor(InstructionTy *I) : Inst(I) {}

Fast way to call an R function from C++?
Hi,
I'm looking for a most efficient way to call an R function from C++ in a
package. I know there are two functions (`R_forceAndCall` and `Rf_eval`)
that can do the "call" part, but both are slow compared to calling the same
function in R. I also try to use Rcpp and it is the worse one. Here is my
test code:
C++ code:
```
// [[Rcpp::export]]
SEXP C_test1(SEXP f, SEXP x) {

Basic function output/scope question
Hello Group,
I'm trying to learn R and am having a problem getting output from a
function I'm trying to write. The problem is clearly one of scope,
but I can't find the documentation that tells me how to get around the
issue.
Here is an example of my problem.
testfunc<-function(x)
{ y<-10
print(y)
print(x)
}
testfunc(4)
The variables x and y are accessible during execution

[LLVMdev] Stack Management in LLVM
First off, thanks for the help so far.
>From what I have been able to tell, emitPrologue kicks in after the arguments
for the function have been copied. For example, consider the function
int testfunc( int foo, int bar );
Emitting assembly code from the llvm-gcc frontend in a small test program
gives the following for the call to testfunc
movl $1338, (%esp)
movl $1339, 4(%esp)

Hi,
I think Chris recently did this with ArrayRef - that might be a good
template to base your solution on?

[ and setMethod conflict?
I noticed this oddity about [ and setMethod.
First, I define testFunc, which sorts a data frame by the first column and
returns the entries that aren't NAs, and testIt, which runs testFunc
repeatedly on a random large data frame, each time saving the return into a
dummy placeholder (for demonstration's sake).

Help needed using 3rd party C library/functions from within R (Nvidia CUDA)
Hello,
I'm trying to combine the parallel computing power available through NVIDIA
CUDA (www.nvidia.com/cuda) from within R. CUDA is an extension to the C
language, so I thought it would be possible to do this.
If I have a C file with an empty function which includes a needed CUDA
library (cutil.h) and compile this to an .so file using a NVIDIA compiler
(nvcc), called 'myFunc.so' I

Deopt operand bundle behavior
Hi!
We have started to use deopt operand bundle to make our native stacktrace deoptimizable and garbage collectable. We stumbled upon an issue and we don't know if it is really an issue on our side or really a problem within LLVM.
For example, for this input:
declare { i8*, i8* } @getCode()
define void @testFunc() {
entry:
%0 = call { i8*, i8* } @getCode()
%1 = extractvalue { i8*, i8* }

categorisation of continuous variables in R
Dear all,
I'm looking for a function comparable to switch, to categorize a
continuous variable in a few levels. Off course that can be done with
a series of ifelse statements, but that looks rather clumsy. I looked
at switch, but couldn't figure out how to use it for this. I guess
that's not possible, as it only works with characters or integers, not
with intervals.
Basically,

Variable passed to function not used in function in select=... in subset
Hello!
I have the problem that in my function the passed variable is not used, but the variable name of the dataframe itself?- difficult to explain, but an easy example:
TestFunc<-function(df, group) {
??? print(names(subset(df, select=group)))
}
df1<-data.frame(group="G1", visit="V1", value=0.9)
TestFunc(df1, c("group", "visit"))

[LLVMdev] New type of smart pointer for LLVM
Hello everyone,
I bring to discussion the necessity/design of a new type of smart
pointer. r215176 and r217791 rise the problem, D5443
<http://reviews.llvm.org/D5443> is devoted to the solution.
r215176 applies several temporary ugly fixes of memory leaks in
TGParser.cpp which would be great to be refactored using smart pointers.

ode() tries to allocate an absurd amount of memory
Hi there R-helpers:
I'm having problems with the function ode() found in the package deSolve.
It seems that when my state variables are too numerous (>33000 elements),

Error in vode(y, times, func, parms, ...) :
