I'm implementing c style "sizeof()", and I did as http://nondot.org/sabre/LLVMNotes/SizeOf-OffsetOf-VariableSizedStructs.txt illuarstrated, and it works find, here's an example of my implementation: auto *p = builder.CreateGEP(structTy, llvm::ConstantPointerNull::get(pointerTy), constint1); auto *size =

It does take one parameter. Here's the important bits: // My Function extern "C" void print(double X) { printf("%f\n", X); } // Args type std::vector<const Type*>

I don't know if the toy program in chapter 4 of the tutorial implementing Kaleidoscope in llvm with C++ is part of your regression suite, but with the version of llvm I installed last weekend, it does not compile: hendrik at lovesong:~/dv/llvm/tut$ g++ -g toy.cpp `llvm-config --cppflags --ldflags --libs core jit native` -O3 -o toy toy.cpp: In member function ‘virtual llvm::Value*

Hi all, can I access the numeric limits of the llvm types, e.g. HalfTy, FloatTy, DoubleTy, etc. in a fashion like the std numeric_limits tool? std::numeric_limits<half>::min() std::numeric_limits<half>::max() In c++API, I want to initialize values and need to know the correct range for the llvm types.... Thx Alex

Hi Albert, I'm having a similar problem and I found I can't declare the function and use it, most likely

I think you might have to provide an empty list if your function doesn't take parameters.

Hi, I'm currently working my way through the tutorial with LLVM 3.9.1 on Windows (finished chapter 4) and stumbled over a few things which could be improved: - "LLVMContext" does not exist as a variable -> "TheContext" - Chapter 3: 5 times - Chapter 4: 1 time - Chapter 5: 4 times - Chapter 6: 2 times - Chapter 7: 2 times 3.4. Function Code

Hello, I would like to know if there is an instruction to convert values from the Int1 type to the Double type in LLVM. I would like to achieve the equivalent of casting a bool value to a double value in C++. Doing the simple CreateSIToFP or CreateUIToFP does not work, it throws an assertion ("invalid cast"). I simply want to avoid branching it's not necessary. What's the

Hello, As I understand, in LLVM IR it cannot be determined whether a register of type int is signed or unsigned. If one wants to convert an integer to a double, which instruction should be used:  "uitofp" or "sitofp" ? We track the values taken by all load instructions and we process them using a function. If the value is a pointer, we use int64 as the type of the function

What does it mean when ExecutionEngine::create returns 0? Here's a simplified example: #include "llvm/Module.h" #include "llvm/ExecutionEngine/ExecutionEngine.h" main() { llvm::Module * module = new llvm::Module("the module"); llvm::ExecutionEngine *ee = llvm::ExecutionEngine::create(module); fprintf(stdout, "pointer is %x.\n", ee); } I

Hi Jin-Gu Kang! It are possible that the problem you are experiencing have already been solved in the current llvm 2.6 release tree and the current svn trunk. So try using llc from llvm 2.6 release branch or llvm pre2.7 svn trunk! It would be helpful if you could open a bugreport for this issue and attach the problematic od.bc since we need a testcase from the bitcode that exposes the bug inorder

The NIST F77 test suite doesn't seem to be compatible with gfortran at all, so I had to work from my own sample codes, and generate test cases from them. Here's what works now, and I have a separate test case for each of these: statement functions intrinsic functions (print, cos, etc) loops, goto statments scalarized array operations function calls with *no arguments* simple common

Dear LLVM members. I am compiling coreutils-7.4 package for ARM linux using LLVM 2.5 version. When i compiled 'od' program in coreutils package using LLVM 2.5, i could see the error message on llc processing. > llvm-gcc -emit-llvm ./od.c -c -o ./od.bc -other-options... > llc -march=arm ./od.bc -f -o ./od.s llc:
