search for: myarray

I was suprised to find that some bitcode I'm generating isn't getting optimized. Here, I'm doing the equivalent of "myarray[5]++" (on an "extern int *myarray"), repeated three times: @myarray = external global i32* define void @update_array() #0 { %1 = load i32** @myarray, align 8 %2 = getelementptr inbounds i32* %1, i64 5 %3 = load i32* %2, align 4 %4 = add nsw i32...

Since myarray is defined as a pointer, not an array, it's theoretically possible that the address therein refers to the same memory location as the pointer itself. I was thinking along those lines, but I haven't been able to come up with a specific instance of what could possibly be aliased. Here are s...

The semantic reason is that the optimizer is required to assume that the i32 stores could be storing to the storage of myarray. LLVM IR does not permit optimizers to optimize based on the nominal types of memory objects or memory accesses. This gets optimized in C, because the C compiler adds special TBAA metadata annotations to the loads and stores which say that the stores of "int" do not interfere with the lo...

...R users I would like to know if there is a way to create a list or an array (or anything) which grows automatically as more elements are put into it. What I want to find is something equivalent to an ArrayList object of Java language. In Java, I can do the following thing: // Java code ArrayList myArray = new ArrayList(); myArray.add("object1"); myArray.add("object2"); .... // End of java code Thanks in advance.

Hey Guys n Gals; I have some arrays that I can't seem to expand correctly (if that's the correct word?), imagine the following example: #!/bin/bash myArray=("First" "Second" "Third") First=("Monday" "Tuesdays" "Wednesday") Second=("One" "Two" "Three") Third=("A" "B" "C") for ((i=0;i<${#myArray[@]};i++)) do for ((k=0;k&lt...

Hi all, I am having a bit of trouble with the array structure of R. What I want to do is dynamically add/remove elements to an array. For example: Let's say I have created an array: > myArray <- array(c(3,8), dim=c(1,2)) > myArray [,1] [,2] [1,] 3 8 And I now want to, for example, push an element (5,6) on to this array so it will read: [,1] [,2] [1,] 3 8 [2,] 5 6 And then pop the first element of the array so the array now reads: [,1] [,2] [...

I"m trying to do a custom sort in this order: 1) Numeric digit furthest right; 2) Alphabetical second furthest to the right; 3) Alphabetical the rest of the string beginning with the first character; The example code I'm using is an array that follows: /myArray <- c('AFP9','AFR9','TLQP7','AFS9','AFR8','AFP8','AFS7','TLQS8')/ The output I desire is: />myArray [1] "AFS7" "AFP8" "AFR8" "AFP9" "AFR9" "AFS9" "TLQP7" TLQ...

...nd I don't see what it has to do with printing matrices with a list type. This is what I means: Suppose my list of S4 objects looks like following: myElement <- setClass("myElement", slots = c(x = "integer")) myList <- lapply(1:8, function(x) myElement(x = x)) myArray <- array(myList, c(2,2,2)) myArray # , , 1 # # [,1] [,2] # [1,] ? ? # [2,] ? ? # # , , 2 # # [,1] [,2] # [1,] ? ? # [2,] ? ? Then I want to wrap the list with a new class and defining a new print method for it. class(myArray) <- "myArray...

Hello everyone, I would like to create a "dynamic" array to keep storing number in it for (i in c(2:length(final))){ myarray <-final[i]-final[i-1] myarray2<-2*final[i] } At the end I would like to use myarray as the x values of an array and the myarray2 as the yvalues of the same array. I tried cbind but it didnot work. Could you please help me with that? Best Regards Alex [[alternative HTML...

Thanks for the suggestions but it doesn't appear to be working correctly for me. I tried building the below after seeing the results with "clang -g -std=c99 test.c" and got the same result LLDB thinks MyArray is 81 elements long even though 81 and 80 doesn't show up anywhere in the llvm-ir (I tried again using an llvm ir file made by clang -g -std=c99 test.c -S -emit-llvm and clang -g test.ll) $ cat test.c int foo(int s) { int MyArray[s]; int i; for (i = 0; i < s; ++i) MyArra...

Hi, I want to store some number of outputs from running a bunch of analyses such as lm() into an array. I know how to do this with a one-dimensional array (vector) by creating myArray <- vector(mode='list', length=10) and storing each lm() result into a component of myArray. My question is, how can do this for a multiple dimensional array? It seems array() does not have such a 'mode' option as in vector(). Any alternatives? Thanks in advance, Gang
