Nick, Thanks for the quick answer. Dereferencing the pointer does yield the same result in both cases but that's not what I want to do. I want to instrument the program dynamically and keep track of certain memory locations which is a problem if the same variable has different addresses for the static/dynamic code - as far I see this is what it's happening but I have no clue why.

Nick, Your solution works well if there is a store instruction in the function but in the case where there is none (i.e. the argument is passed on directly to another function), creating a store does not help to get the memory address of the variable which takes me back to my initial question at http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-May/022590.html - isn't there a way to obtain the

That makes pointers illegal in the SelectionDAG. As far as I understand it, it is the backends job to legalize these nodes by using the ReplaceNodeResults/LowerOperation callbacks.

Hello, everyone I have a piece of code that looks like this: mrets <- merge(mrets, BMM.SR=apply(mrets, 1, MyFunc, ret="BMM.AV120", stdev="BMM.SD120")) mrets <- merge(mrets, GM1.SR=apply(mrets, 1, MyFunc, ret="GM1.AV120", stdev="GM1.SD120")) mrets <- merge(mrets, IYC.SR=apply(mrets, 1, MyFunc, ret="IYC.AV120",

Hi, I would like to evaluate a function, with 3 arguments, for instance, myfunc<-function(a,b,c) { sqrt(a)-exp(b)+4*c } How to execute myfunc(x,y,z), for all x, all y and all z, where x,y,z are vectors?

Can someone help me with this simple example? sq <- function() { y <- x^2 y } myfunc <- function() { x <- 10 sq() } myfunc() executing the above in R yields: > myfunc() Error in sq() : Object "x" not found I understand that R's scoping rules cause it to look for "x" in the environment in which "sq" was defined (the global environment in

Hi all, is there a way to extract the name of a function, i.e. do the reverse of match.fun applied to a character string? I would like to print out the name of a function supplied to another function as an argument. For example: myFunc = function(x) { x+1 } applyFunc = function(fnc, x) { fnc = match.fun(fnc) fnc(x) } Is there a way to obtain "myFunc" from the argument fnc in

R-help, I am trying to create a function that i pass a data set to and have the function return some calculations based on data. Allow me to illustrate: myfunc <- function(lst,mn,sd){ lst <- sort(lst) mn <- mean(lst) sd <- sqrt(var(lst)) return(lst,mn,sd) } data1 <-c (1,2,3,4,5) data2 <- c(6,7,8,9,10) myfunc(data1,data1mn,data1sd) myfunc(data2,data2mn,data2sd)

Dear all, It has been ages since I studied integration in college. Right now I try to recover all this kind of knowledge and then try to understand how integration works. Thus I am doing some first 'experiments' and I would like to request your help and comments. I have the function: p2<-function(x){0.5*(3*x^2-1)} # I found the square of p2 by using some pencil and

Hi, Suppose I have a function: myfunc <- function(x, y) { ... } And within the function I want to print out the name of the x, y vectors. For example, if I do: > myfunc(foo, goo) [1] "foo" "goo" It shall return "foo", "goo" (with or without quotes is fine), where foo and goo are two vectors with numbers. I know this sounds strange, but I'd

I am wriitng an LLVM pass to insert instrumentation at certain points of the program. I want to pass the `StringRef` obtained from `getName()` as a parameter to a function `func(char* s)`. I can allocate some space on stack using `AllocaInst` to generate an `alloca` instruction. But, how can I copy the `StringRef` to the stack space? -- Thanks & Regards, Dipanjan -------------- next part

Dear R users, I want to retrieve "..." argument values within a function.

Dear R Helpers, I have about 20 data frames that I need to do a series of data scrubbing steps to. I have the list of data frames in a list so that I can use lapply. I am trying to build a function that will do the data scrubbing that I need. However, I am new to functions and there is something fundamental that I am not understanding. I use the return function at the end of the function and

The name conflicts in Epi and ROC packages (2 'ROC' functions are the problem) cause the following code to work once, but not twice: library(MASS); data(cats); x = cats[,2] y = ifelse(cats[,1]=='F',0,1) library(Epi); ROC(x,y,grid=0)$AUC library(ROC); AUC(rocdemo.sca(y, x, dxrule.sca)) What is the standard way of resolving name conflicts?
