similar to: IRBuilder Assignment ( '=' ) operator?

However I need the standard assignment operator so I can assign the value of a temporary to that of another temporary, or to create a new temporary from an existing one. - Paul ________________________________________ From: Tim Northover <t.p.northover at gmail.com> Sent: 16 March 2016 13:11 To: Paul Hancock Cc: llvm-dev at lists.llvm.org Subject: Re: [llvm-dev] IRBuilder Assignment (

I partially worked out that to do an assign I will need to manually assign a temporary first and then load data into it, which also means I'll need to set up a temporaries list in my code assembler as allocations must be done before anything else? or is it fine to allocate a variable mid-way through a function and the compiler will manage it? With that as well, if I had a function that loads

I've got a ticket open where I would very much like some input from maintainers of other languages that rely on llvm and use the IRBuilder. See: Teach the IRBuilder about constrained fadd and friends: https://reviews.llvm.org/D53157 I'm adding support to functions like CreateFAdd() the ability to optionally emit the constrained math intrinsics required to support strict floating point

I don't think it's the same problem as you described. By printing I meant calling printf function and passing my global variable as one of the arguments. My code: Instruction* InstructionVisitor::incrementGlobalKey(Instruction* I) { IRBuilder<> Builder(I->getContext()); Builder.SetInsertPoint(I->getNextNode()); GlobalVariable* key =

Hi Everyone, I'm quite new to LLVM and I want to update value of global variable in LLVM IR. I created new global variable in ModulePass: bool runOnModule(llvm::Module &M) { IRBuilder<> Builder(M.getContext()); Instruction *I = &*inst_begin(M.getFunction("main")); Builder.SetInsertPoint(I); M.getOrInsertGlobal("globalKey",

It seems that the problem was because I used builder.CreateFAdd to create a <2 x double> vectortype FADD instruction. It works if I use it to create the scalar version FADD. I want to have an instruction like: *%2 = fadd <2 x double> undef, <2 x double> undef. *The following is the way I used to create the vectorized FADD instruction: //pInst is a double type instruction

Thanks Nick, that's something what I am trying to implement as the following. But it seems I still only get the constant value not the instruction. Could you please go over the following instruction and see what wrong with it? Thanks for your time again. Value *vecVal = NULL; IRBuilder<> builder(&*pInst); Type *vecTy = VectorType::get(Type::getDoubleTy(ctxt), 2); Value

I got it. Thanks, Nick. So, it is back to the previous problem. If I have the following instruction: %3 = fadd double %1, double %2 I want to change it into %6 = fadd <2 x double> %4, double %5 where %4 = <double %1, double %1>, %5 = <double %2, double %2>, how can I do this?

Hi LLVM, IRBuilder can fold constants (that behaviour can be controlled by Folder type). What do you think about optionally allow IRBuilder to eliminate no-op instructions like `add %a, 0` or `memcpy(%a, %b, 0)`? - Paweł -------------- next part -------------- An HTML attachment was scrubbed...

I am trying to get a handle on IR builder, at least some basics. I ran through a tutorial here: Create a working compiler with the LLVM framework, Part 1 <http://www.ibm.com/developerworks/library/os-createcompilerllvm1/>, and it worked well enough. I have some simple code that creates a hello world IR. I am trying to now bring in some concepts from the Kaleidoscope tutorial, namely

Value * is the instruction. use dyn_cast<Instruction> to get to it. On Thu, Apr 16, 2015 at 11:39 PM zhi chen <zchenhn at gmail.com> wrote: > But IRBuilder.CreateXYZ only returns a "VALUE" type.

I want to create an add instruction that takes two constant operands at the LLVM IR level. I use the IRBuilder class, but nothing happens. Here is part of the runOnFunction() method of my function pass: ... LLVMContext &Context = F.getContext(); IRBuilder<> builder(&Instruction); Value *Lef = ConstantInt::get(Type::getInt32Ty(Context), 4); Value *Rig =

Hello, I have an optimisation issue in an llvm IR pass - the issue being that unnecessary instructions are generated in the final assembly (with -O3). I want to create the following assembly snippet: mov dl,BYTE PTR [rsi+rdi*1] add dl,0x1 adc dl,0x0 mov BYTE PTR [rsi+rdi*1],dl however what is created is (variant #1): mov dl,BYTE PTR [rsi+rdx*1] add dl,0x1 cmp

Not sure that works.  I had that initially: auto cf = IRB.CreateICmpULT(Incr, ConstantInt::get(Int8Ty, 1)); auto carry = IRB.CreateZExt(cf, Int8Ty); Incr = IRB.CreateAdd(Incr, carry); it makes no difference to the generated assembly
