I really can't figure out how to get and set array indices from the c interface. so to get an element I'm calling tindex = *fn\SymbolTable(*index\name) index = LLVMBuildLoad(builder,tindex,"index") arr = *fn\SymbolTable(*array\name) arrptr = LLVMBuildLoad(Builder,arr,"arrayptr") tmp = LLVMBuildGEP(Builder,arrptr,index,0,"ptr") ptr =

Is there any reason this generated code won't run in the Jit? I've pretty much got everything else working for my front end which all runs fin in the Jit but I can't get global arrays to work. ; ModuleID = 'test' target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32" target triple

Hello, I'm trying to get to grips with the c interface of llvm intending to eventually develop a front end for Purebasic Though I've hit the wall already writing an iterative Fibonacci function. While I think the module dump looks ok it doesn't work for any input > 2 the function returns 2, the loop only executes once Hopefully someone can see what the problem is from the

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.

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

Hello When a call comes in, I'd like to fork a Python script that broadcasts a message so that users see the CID name + number pop up on their computer screen, and simultaneously ring their phones. The following script doesn't work as planned: It waits until the script ends before moving on to the next step, which is Dial(): =========== exten =>

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

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"

I am new to R. I try to search the web but could not find the answer so I post it here asking for help.

Hi Mikael, You are obtaining warning, not an error, right? The most arm cores, including arm1136, can execute mul with rd = rm. So, you can ignore this warning.

Hello all, My app is using LLVM JIT as a runtime engine for image analysis (similar to opencl). I'm placing values into a struct to pass byref to a series of functions. After running the createStandardModulePasses(...) set of optimizations, the function calls are all inlined but the struct store/load pairs haven't been optimized away. I've attached the code below. What I'd like to

The following seemingly identical functions, get compiled to quite different machine code. The first is correctly optimized (the computation of var y is nicely moved into the else branch of the "if" statement), which the second one is not (the full computation of var y is always done). The output was produced using the demo page on llvm's web site (optimization level LTO). Can

Hi! I'm just getting started with R (and with the analysis of large datasets in general). I have several beginner-level questions whose answers I have not been able to find, and was hoping one of you would be kind enough to throw me a cluebrick or two. I have a 6-dimensional numeric array (which I'll call myarray) that is "fully named". By this I mean that non-NULL dimnames
