similar to: [LLVMdev] noob IR builder question

I create a function with an empty signature: void llvm_start_new_function() { llvm::outs() << "Staring new LLVM function ...\n"; Mod = new llvm::Module("module", llvm::getGlobalContext()); builder = new llvm::IRBuilder<>(llvm::getGlobalContext()); llvm::FunctionType *funcType = llvm::FunctionType::get(builder->getVoidTy(), false);

I am trying to build a function (C++ Builder) and at the same time extend its parameter set. Here's what I try to do: Value* arg0 = add_param_float("arg0"); Value* tmp = builder->CreateFAdd(arg0,some_previous_value); Value* arg1 = add_param_float("arg1"); The function add_param_float should add a 'float' parameter to the function and return its value. Right

Thank you Chris. I am using llvm-3.4.2. I am facing the same issue when using clang++ as well. $ clang++ try.cpp -D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS `llvm-config --cxxflags --ldflags --libs` -S -emit-llvm gives me errors $clang++ try.cpp -D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS -S -emit-llvm $ lli try.s gives me Program used external function

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*

Hola LLVMers, I'm getting a crash when using ConstantFP::get. I can repro it by adding one line to the Fibonacci example program: int main(int argc, char **argv) { int n = argc > 1 ? atol(argv[1]) : 24; // Create some module to put our function into it. Module *M = new Module("test"); // We are about to create the "fib" function: Function

It's in debug. I'm having a look at the assembler it's producing right now and it's definitely a little odd for what should be a simple assignment in zeroSignificand. ________________________________ From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Dale Johannesen Sent: Wednesday, September 05, 2007 2:39 PM To: LLVM Developers Mailing

Hola Dale, I spent some time walking through what's going on with a friend of mine from VStudio. Category is given 2 bits in the APFloat class definition. It's sign extending the enum value for the comparisons when it loads it out of the class, so the 2 becomes a -2 and the comparison fails. He sent me a piece of code which I might be able to use to force the issue. I'll update

Hi, I want to create a double constant from a float constant, here's my code: auto* constFloat1 = static_cast<llvm::ConstantFP*>(llvm::ConstantFP::get(llvm::Type::getFloatTy(context), 3.1)); assert(constFloat1->getType() == llvm::Type::getFloatTy(context)); auto* constFloat2 = llvm::ConstantFP::get(llvm::Type::getDoubleTy(context), constFloat1->getValueAPF());

Hi, When I run opt on the following LLVM IR: define i32 @foo() { bb0: %0 = bitcast i32 2139171423 to float %1 = insertelement <1 x float> undef, float %0, i32 0 %2 = extractelement <1 x float> %1, i32 0 %3 = bitcast float %2 to i32 ret i32 %3 } -> It generates: define i32 @foo() { bb0: ret i32 2143365727 } While tracking the value I see that the floating point value

Hi All, At some point in the next week or two I'm going to remove the ConstantFP::get(type, APFloat) method. Right now, you can immediately fix your code by dropping the first 'type' argument. For example, if you have: ConstantFP::get(Ty, APFloat(1.0)) just change it to: ConstantFP::get(APFloat(1.0)) Both forms work with SVN head right now so you can migrate as

Does anybody else have an opinion on this issue? I'm planning to submit a patch which would add a new get method for ConstantDataVector taking an ArrayRef<Constant*> and use that in the few places in constant propagation where convertToFloat is used. Let me know if you think there is a more obvious way to do it. Right now the only way to create a ConstantDataVector are those method:

Hi, I am upgrading my project from 3.7 to 3.8. I find that following code used to compile in 3.7 but doesn't in 3.8 and I can't understand why. llvm::Function *mainFunc = ...; auto argiter = mainFunc->arg_begin(); llvm::Value *arg1 = argiter++; arg1->setName("obj"); But if I change the code to following it compiles: auto argiter = mainFunc->arg_begin(); llvm::Value

Sorry to bother you about a S-Plus related problem, but I hope someone can help. I have tried to "translate" some code from R to S-Plus (I have colleague that insists on using S-Plus. And yes, I have tried to make him change to R...) The following code works out fine in R, but in S-Plus (S-PLUS 6.2 for Windows Professional Ed.) I get the error message "Problem in est.theta(x):

Hi Sanjay, Thanks, I saw this flag and it's definitely should be considered, but it appeared to me to be static characteristic of target platform. I'm not sure how appropriate it would be to change its value from a front-end. It says "Has", while optional flag would rather say "Uses" meaning that implementation cares about floating point exceptions. Regards, Sergey

Hi all, translating the following c code to llvm c++Api code, I can not understand the result. Perhaps someone could explain it to me. c code --------------------------------- struct stest { int age; float weight; } foo={44,67.2}; int main() { foo.weight=68.2; ... ---------------------------------------- API code // this is clear ConstantFP* const_float_102 =

Hi! I'm trying to learn LLVM and I want to compile the Kaleidoscope compiler. according to: http://llvm.org/docs/tutorial/LangImpl3.html I'm compiling it with: clang++ -g -O3 test.cpp `llvm-config --cppflags --ldflags --libs core` -o toy and it indeed works. The problem is that when using eclipse it forces me to divide the compilation into two steps: g++ -O0 -g3 -Wall -c
