Hello everyone, I want to pass a set of integers using metadata but I don't know how. I have tried: the integers are in array[] *1. * LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } *is->setMetadata("path",MDNode::get(C,values));* failes when setMetadata(),

I also tried the following, with no compilation errors, but segfault, core dumped: *LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } llvm::ArrayRef<Value*> bla = values[size]; is->setMetadata("path",MDNode::get(C,bla));* On Fri, May 3, 2013

Hello, using the LLVM API, I've build one very simple function that adds two ConstantInts and returns the result. I noticed that, when I emit IR code, it is optimized to a simple "ret i16 42" when I add 40 and 2. I'd like to see the operations that are necessary to compute the result, though. Can I somehow disable this optimization in the pass, leading to more verbose IR code?

...ckage "simsalabim". I ran command decompSSA with L = length(Amps)/5 The reason is that I have SSA/MTM toolkit running in Mac/OS. SSA/MTM documentation, relative to SSA, recommends that N/10 <= L <= N/5. Documentation of simsalabim package recommens that L=N/2 I ran the command getSignal and felt uncomfortable at picking values for parameters C0 and r0. I would appreciate some suggestion/guidelines because these values seem to influence the trend extraction. I chose C0=0.0005, r0=0.0005 which are both below the Nyquist frequency 1/Amps.dc$L = 0.0007223346 As a consequence, getSi...

IRBuilder is a templated class, and one of the template arguments is the constant folder to use. By default it uses the ConstantFolder class which does target-independant constant folding. If you want to disable constant folding you can specify the NoFolder class instead, i.e. declare the builder as follows: IRBuilder<true, llvm::NoFolder> builder(body) On 26 Nov 2013, at 19:23, Daniel

Hello everyone, I was able to get all the execution paths between 2 points (basic blocks) in my program (with the condition to traverse a loop only once). I mapped all the basic blocks to integers and created a correspondent directed graph. I was able to get all the paths (a path is represented by an integer identifier). For my target program I have 72 paths, but the program hangs unexpectedly

As an update, it is a memory problem which I don't know how to fix. I tried to skip the problematic piece of code when in the case when the loop hangs. So I did something like : if( instr ) { LLVMContext& C = instr->getContext(); Value* values[cnt]; errs()<<"\ngy: \n"; if(!(desters==7)){ // this

Hi, I don't know much about this issue, but this malloc error won't be solved by a change to delete[] or free. In fact, if you use the incorrect one for simple types, you may not notice it. The error you have seems to me like a memory corruption because you went out of bound and corrupted the memory somewhere, Valgrind may help you figure out what is going on. Cheers, Matthieu

Hi. Is it possible to make gpr from raw? library(aroma) #read gpr file gpr <- GenePixData$read("gpr123.gpr", path=aroma$dataPath) # gpr -> raw raw <- as.RawData(gpr) # raw -> ma ma <- getSignal(raw, bgSubtract=FALSE) ma.norm <- clone(ma) #normalization normalizeWithinSlide(ma.norm, "s") #ma -> raw raw2 <- as.RawData(ma) I want to make gpr data from raw2 and then I want to write new gpr( write(gpr,¡±result.gpr¡±)). Is it possible? Can anyone help me with this? Thanks...

I am programmatically building some functions in intermediate representation, and trying to verify them, but the verifier always reports that there is a problem, and I can't see why. Minimal test case: #ifdef _MSC_VER #pragma warning(disable : 4141) #pragma warning(disable : 4530) #pragma warning(disable : 4624) #endif #include <llvm/IR/IRBuilder.h> #include <llvm/IR/Verifier.h>

I think the better solution should be: LLVMContext& C = is->getContext(); Value *values[] = { ConstantInt::getSigned(Type::getInt64Ty(C), *scsr*), MDString::get(C, *"path"*) }; lnstr.setMetadata(*"your_analysis_name"*, MDNode::get(C, values)); So that you can take advantage of the type system of LLVM bitcode, and don't have to cast the integers from/to strings

Yes, it sounds good. I can try tomorrow. Thank you for your advice !

Hi, I need to control IRBuilder(or manage IR building with other means) very strictly. The problem is in the realm of ConstInt/GlobalVariable handling, more precisely: LLVM converts llvm::ConstantInt values to GlobalVariable addresses ad-hoc if I store a constant in a GlobalVariable, and it appears to me, that I can do nothing about it. Consider the following, shortened code: ... 0x18: r2 =

Hello all, I set: InitRoots = true; in my gc plugin as i want the roots to be initialized to the "null" value. Is there a way to define which value should be the initial one? For example, i would like to initialize my roots to -5 (tagged, null value for the GC in my runtime system) instead of 0. Ofcourse, i could do it in the frontend (storing -5 to all GC roots), but i was wondering

Hello Duncan, Yes, I built it with assertions and I have also debug info.

Hi Alexandru, did you build LLVM with assertions enabled? If not then you should do. Ciao, Duncan.

The problem is that I want to pass only srsr which is an int. "marked" was just an example :) Thanks you!

As an update, here is the current piece of code: Inside a loop iterating over each basic block : *std::vector<Value*> values; values.resize(cnt); //std::vector<Value*> values(sizeof(Value*)*cnt); //SmallVector<Value*,cnt> values; if(is) { LLVMContext& C = is->getContext(); errs()<<"\ni: \n"; for(i=0;i<cnt;i++){

Hello everyone, I have an integer and I want to convert it to StringRef in order to set metadata. setMetadata->(StringRef, MDNode*); It is there a native LLVM way to do it? 1. In the llvm::APSInt Class is toString() method, which seems it is not for this purpose 2. itoa and string are not part of LLVM 3. stringstream is not part of LLVM 4. to_string is not part of LLVM 5. any casting method?
