similar to: [LLVMdev] Illegal BitCast assertion failed

ok.. you are right. I had not inserted the AllocaInst in the function. Thanks a lot for solving my problem yet again :) --- On Mon, 11/17/08, Eli Friedman <eli.friedman at gmail.com> wrote: > From: Eli Friedman <eli.friedman at gmail.com> > Subject: Re: Assertion `castIsValid(getOpcode(), S, Ty) && "Illegal BitCast"' faile > To: bhavi63 at yahoo.com

ok.. So I am trying out what you have suggested. I have written the below code which basically tries to write the constant 10 to a file. myprint is a function pointer to a function which takes char * parameter and writes it to file. Value *Ten = ConstantInt::get(Type::Int32Ty, 10); const Type *VoidPtrTy = PointerType::getUnqual(Type::Int8Ty); AllocaInst *AI = new AllocaInst(Type::Int32Ty); Value

Ah! I get it now. Thanks a lot ! I changed it to BitCastInst(AI,VoidPtrTy,"",j); And now I am getting the following error :(. I have been stuck with this error before also. I know I am missing out something silly. What is the cause of this error and Please let me know how to fix it. /home/bhavani/llvm/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp:1130: llvm::SDOperand

Thanks Nick! ok. I ran through the verifier and this is the issue: verifying... Instruction does not dominate all uses! %tmp3 = add i32 %b, %a ; <i32> [#uses=2] store i32 %tmp3, i32* %0, align 4 Broken module found, compilation aborted! add is existing instruction in function. store is the instruction I have added to the function. How do I fix this now :(? Thanks, Bhavani --- On Mon,

ok 1 last question for the day... I created a function in C. void writeToFile(char *str) { FILE *f; if((f=fopen("example","a"))==NULL){ printf("could not open file"); } else{ fprintf(f,str); fclose(f);} } used this to create .bc then using llc -march=cpp I got the cpp code to create this function. While instrumenting my code, I place call to this function.

I am new to LLVM and couldn't find any llvm-user list, so I am posting my user question here, sorry. I am trying to create a simple "puts" call accepting the static string, with the code below. The last line (CallInst::Create) fails with an assert: "Calling a function with a bad signature!" Because the type of function is void(u8*) and the argument supplied is:

So, you need to bitcast `pinst` to a pointer to Vector of double, since it (I hope for your sake) is a pointer to integer. What you are trying to do is bitcast a pointer into a vector, which probably will lead to an assert or "bad code that doesn't work". -- Mats On 15 April 2015 at 21:57, zhi chen <zchenhn at gmail.com> wrote: > What I want to do is to change the pInst

Hi, I'm installing a laptop for a friend of mine, and while most things work, the Sony memory stick does not. With respect to the HEADS UP of August 7th, I've also re-enabled the 2 Sony memory sticks quirks, in sys/cam/scsi/da_scsi.c. The symptoms also apply to 4.8-RELEASE: umass0: Sony USB Memory Stick Slot, rev 1.10/1.80, addr 2 ... umass0: CBI reset failed, TIMEOUT umass0: CBI

Hello! I was wondering if it's possible to see the actual code of checkTmvArgs function that is part of the code for rtmvnorm (which is below - I just typed "rtmvnorm" on the prompt). I get an error: Error in checkTmvArgs(mean, sigma, lower, upper) : sigma must be a symmetric matrix At the same time I am pretty sure that the matrix I am passing as sigma is a var-covar matrix

I am trying to dyn_cast a Value* to a BitCastInst. The dump of what I want casted is "i8* bitcast (i32 (i32)* @f1 to i8*)", so it is a BitCastInst. For someone my dyn_cast always fails, does anyone see why? arg->dump(); BitCastInst *bitcast = dyn_cast<BitCastInst>(arg); assert(bitcast != NULL); Thank you

I am trying to change this define void @main(float* noalias %arg0, float* noalias %arg1, float* noalias %arg2) { entrypoint: %0 = bitcast float* %arg1 to <4 x float>* intothis define void @main(float* noalias %arg0, float* noalias %arg1, float* noalias %arg2) { entrypoint: %0 = getelementptr float* %arg1, i64 0 %1 = bitcast float* %0 to <4 x float>* I must be close but

My pass is looking at StoreInsts acting on global variable that happen to be function pointers. From these StoreInsts I would like to get useful information(the function used if a direct assignment, function pointer used, etc) from the getValueOperand() method. Looking through several examples I see that this can return several things like: GlobalVariable, Function, LoadInst or BitCastInst

Greetings - Maybe I''m a bit slow, but I''ve been trying to understand how to use a module for the better part of a day and I''m not getting it. Here''s what I''ve done: Using puppet 0.23.2 1. Downloaded the shorewall module from David Schmitt''s git repo (Thanks David!!!!) and placed it in the directory /var/lib/puppet/modules (using the rpm

Dear R-devel, Last week I got several responses to my question about debugging segfaults in my code (original post below). After I changed the S_alloc() calls to Calloc()/Free(), the symptom was gone, but I was told to keep looking. So I did: o Switched to Calloc/Free. Electric Fence did not find any problem. o Put assert(index < bound); assert(index >=0); everywhere in the C routine

Hi, I am writing an alias profiler using the points-to relation. For this I'm inserting a function call of external function with the following type profile(int,int,int,void*,void*,...) I'm trying to pass the dereferenced pointer's memory address and the address of the location who are in alias set of the pointer. For this i'm using BitCastInst BitCastInst *init1= new

(Sorry for the cross-post--- I wasn't sure which list is more appropriate...) Hi everyone, I've run into segfaults when using my randomForest package on large dataset (e.g., 100 x 15200) and large number of trees (e.g., ntree=7000 and mtry=3000). I'm wondering if anyone can give me some hints on where to look for the problem. The randomForest package mainly consists of two things:
