similar to: [LLVMdev] Loop IR insertion

Hi, From the file HowToUseJIT.cpp, I learned how to insert some calcuation IR code like Add/Sub/Mul etc by using Instruction *Add = BinaryOperator::createAdd(One, ArgX, "addresult", BB); By following this way, it works well when I insert some IR code whose operand is integer type like IntTy, however, when I tried to insert similar thing whose operands are float point, I got the

Valery, Attached are three files: "valery.cpp" which contains your original, "reid.cpp" which contains corrections to most of the FIXME items and "diffs" which shows the differences between them. The differences should be instructive on what to do. You were really, really close .. just a few details changing. The code in "reid.cpp" compiles but I

Reid Spencer, thank you for your quick responce, finally i got to my PC at home.

Fantastic! It's working! Thank you so much Craig!!! On Fri, Apr 7, 2017 at 6:05 PM, Craig Topper <craig.topper at gmail.com> wrote: > It should be VectorType::get(Type::getInt32Ty(Context),4).

Hi LLVMers, the example attached I have used to prove that JIT and some visible optimizations are really invoked. Proved OK. I got 30% speed-up in comparison to gcc 3.3.3 on my Athlon XP 1500. Nice. P.S. guys, no fears, I don't plan to flood the cvs repository with my "brilliant" examples ;) --- Valery A.Khamenya -------------- next part -------------- An

Here's an idea: how about we take the ModuleMaker, Valery's previous example, and this one and put them all in one "small examples" project? -Chris > Valery A.Khamenya wrote: > >

Valery, I have to agree with Misha on this. None of us knows "everything" about LLVM and as you can see, Misha responded three hours before I did :). Asking questions here is encouraged, so please feel free to post them on LLVMdev. We'll always help where we can. Thanks, Reid.

On second thought, the makefiles don't (easily) allow this do they? You can only build one program per directory. Were you suggesting that you wanted me to move the entire directories under a "small examples" directory? Reid.

Valery, First response of several. I don't know why the demo page at UIUC is unavailable but there is an enhanced copy of it running on the mirror at http://llvm.x10sys.com/demo/ if you ever need it. Running it produced the following LLVM equivalent for the C code in your example. implementation ; Functions: int %add1(int %x) { entry: %tmp.1 = add int %x, 1 ; <int> [#uses=1]

Hi, I am trying to insert a function into the LLVM IR. But i get a stack dump exception. My code is as follows.   #include "llvm/Pass.h" #include "llvm/Function.h" #include "llvm/Module.h" #include "llvm/Support/raw_ostream.h" #include "llvm/ADT/Statistic.h" #include "llvm/Support/IRBuilder.h" using namespace llvm;   namespace {

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

Hello guys, I wonder how I can change the type of an integer variable. For instance, given the instruction "%3 = add i32 %1, %2" I would like to alter the instruction to "%3 = add i16 %1, %2". Is there any way to do this? Best wishes, Douglas -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, Nick, thanks for the reply. I still have a problem: I only need to "clone" an Instruction, changing its type. That is, I would like to keep all characteristics of the old Instruction and create a new one only with a different type. I am trying create a new Instruction thus: %3 = add nsw i32 %1, %2 ; <i16> [#uses=2] //Old Instruction Value* Op0 = I->getOperand(0); Value*

Hello, I have just started using llvm. I was trying to debug how *clang* generates IR for very simple C testcases (few assignments and if-condsitions). To get a hold on the basic functions, I put some break points on following functions but debugger *didn't stop*: llvm::BasicBlock::Create llvm::BinaryOperator::CreateAdd (design has binary op) llvm::Value::Value llvm::BranchInst::Create
