Hi, I need to pass some arguments to CreateCall function (as Value *). For example, I need to pass a 64 bit integer (with a value I calculate). How can I convert the 64 bit integer to a value * in order to pass it? Thanks a lot, Tehila. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.ll...

Hey guys, Whys are there like 5 variants of CreateCall in IRBuilder<> with numbers appended to them? The only difference I can see is the number of arguments. Aren't C++ function overloads be suited for this? Félix

The only difference I can see is the number of arguments. Aren't C++ function overloads be suited for this? An overload could work, but this sort of API makes it more obvious which one you're trying to call and avoids overload ambiguity e...

Hi I want to insert some functions into the llvm bitcode ir files. So I use IRBuilder and CreateCall(). But it how error : inlinable function call in a function with debug info must have a !dbg location. I don't know what DebugLoc should I give the new CallInst to setDebugLoc. I Create this CallInst , so this CallInst doesn't hava so-called "DebugLoc" mapping to the source co...

Hello, I am adding function calls to an LLVM link-time optimization (LTO) pass, using the IRBuilder::CreateCall method. I want these calls to remain in the final x86 binary at any optimization level, but on levels -O2 and -O3, some of these calls are being optimized out. So far, I've tried adding each function in the program (excluding LLVM intrinsics) to the llvm.used set, and I've also set noinlin...

...ode generation time.) More exactly, I would like to give something LIKE this in a middle-tier pass (I haven't tried this code in LLVM): Value *instrinsicFunc = Intrinsic::getDeclaration(M, Intrinsic::my_intrinsic); myIRBuilder.CreateCall(repeatFunc, "string_that_llc_codegen_should_output_as_assembly"); So my intrinsic would be accepting a general string which will be used at codegen to be output. I guess I would have to define it like this in a .td file: def int_my_intrinsic : Intrinsic<[], [string]...

Hi all. I am using LLVM to develop a procedural language. Can anybody point me to an example that uses CreateCall for a non-tail call? I am having trouble doing anything with the return value from the call besides returning it immediately. i.e. Passing the CallInst created by CreateCall to CreateRet is working fine, but I am having trouble storing the returned value in a local variable or passing it to anoth...

..., i32)*, void (%Foo*, i32)** %8 However, the builder->CreateLoad instruction corresponding to the line with %9 returns null: llvm::Function *calleeMethod = llvm::dyn_cast<llvm::Function>(builder->CreateLoad(calleeMethodPtr)); So if I then try to execute the following builder->CreateCall function I end up with a segmentation fault since calleeMethod is null: builder->CreateCall(calleeMethod, argVals); Under what circumstances would builder->CreateLoad return null? Is the global vTable's memory not allocated correctly? Or have I been approaching this incorrectly - is...

I guess currently we do not have these arithmetic with overflow variants in IRBuilder . So CreateCall is the only way to do it. Is it a good idea to add them into the IRBuilder? even thought they are in turn implemented with CreateCall only? - sanjiv -------------- next part -------------- An HTML attachment was scrubbed...

...rone. Maybe we should either: - update the API to enforce the CC when building a ``CallInst`` - update LangRef to state that mismatching CC in static call is an error (note that LangRef is unclear about static call, the quote only references indirect calls) - add an optional setting in the ``CreateCall`` that enforces CC (and let it default to yes?) Any thoughts on that? Serge

.... Let me explain my intention first. I want to retrieve the value (if isPointerTy() returns true) to be stored by a store instruction at run-time and pass on that value as either an unsigned int (64) or a pointer (char*) to an external function. The call to that function is inserted using IRBuilder.CreateCall(). Consider the code snippet below. ================================================== if (StoreInst *store_inst = dyn_cast<StoreInst>(&I)) { Value* vo = store_inst->getValueOperand(); uint64 var_value = /* cast vo to unsigned int 64 bit */...

In C code, I would just call "foo_ptr(var)", and it would just work. But, replacing the function name with the name o...

...ckrestore instruction). The call function is created something like this (paraphrasing from lib/Transfoms/Instrumentation/AddressSanitizer.cpp): // call __asan_allocas_unpoison(uptr top, uptr bottom); // NB "top" here means lowest address and "bottom" means highest! IRB.CreateCall( AsanAllocasUnpoisonFunc, { IRB.CreateLoad(DynamicAllocaLayout), IRB.CreatePointerToInt(SaveRestoreInst->getOperand(0), IntptrTy) } ); I think the problem is that the operand to stackrestore is the new native sp register value to restore, and this code is assuming that...
