Hello all, >From what I have observed, using `Inst->replaceAllUsesWith` does not replace uses of the `Inst` in `ConstantExpr`s. Is there some way to have a universal replaceAllUsesWith? Thanks, ~Siddharth. -- Sending this from my phone, please excuse any typos! -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org...

Whoops, sorry, I meant "value->replaceAllUsesWith". Should I create a new post with an updated title?

Hello LLVM-World, currently I play around with a "llvm::Module" and an external function defined there "puts". Normally this function gets resolved in the JIT-Process but I wonder about two things: 1. Can I resolve the function already in this step? I used "replaceAllUsesWith" and passed a "llvm::ConstantInt" to the function. But this didn't worked. 2. What might happen if I have two modules and use "replaceAllUsesWith" on a function of Module A, passing a function of Module B. Thank you for the help in advance! Kind greetings Björn Als...

Hello, I wonder if someone would know what is going on below. All of a sudden I’m getting this assertion thrown: Assertion failed: (New->getType() == getType() && "replaceAllUses of value with new value of different type!"), function replaceAllUsesWith, file /Users/meister/Development/externals-clasp/llvm36/lib/IR/Value.cpp, line 345. It’s happening when DIBuilder::finalize is being called at the end of a source file compilation. Here’s the most illuminating debugging information I could pull out of a frame: (lldb) frame #6: 0x0000000103a67c...

...g an assertions I added a few weeks after that commit in the Metadata RAUW method. But it is the equivalent assertion in Value::RAUW that you are hitting and that has been there forever. Looking at your exact revision, the assertion seems to trigger while executing: > > DIType(TempEnumTypes).replaceAllUsesWith(Enums); > > in DIBuilder::finalize(). Can you check if TempEnumTypes is null at this point? If that is the issue (which I’m not sure), then you need to call DIBuilder::createCompileUnit() at some point. > > Fred I had a thought, too: are you using two different `LLVMContext`s? That...

Thanks, but I replaceAllUsesWith() - works well, but I still get bug in eraseFromParent(): While deleting: i32 (%class.B*, i32)* %_ZN1B1xEi An asserting value handle still pointed to this value!

I'm not sure if I followed correctly, but you can't replace a function declaration with a constant int.

I could actually track down the cause of the problem: mainModue->getFunction("puts")->replaceAllUsesWith( llvm::ConstantExpr::getPointerCast( llvm::ConstantInt::get(llvm::IntegerType::get(context, 64), 0xF), mainModue->getFunction("puts")->getType() ) ); The problem is the line where I receive the type of the function "puts", it will crash the application - when used as the p...

Hello, The problem I'm having is that I modify a function body by using 'Value::replaceAllUsesWith' and then execute it with the JIT engine several times but I always get the output from the first iteration for all the iterations. This is what I do: I generate the following 2 functions on the fly based on the FunctionType of the declaration below in C code. define i32 @get_int_5(i...

Hi, I am trying to replace a global variable with a constant. I did manage to do it, but somehow it appears to be fairly bruteforce by just iterating over all functions/bblocks/instructions and filtering for those that load the variable and replacing the instruction with Instruction::replaceAllUsesWith(). The more intuitive way of iterating over the uses of the variable did not work out as I have to replace the whole instruction instead of just the operand (as GlobalVariable::replaceAllUsesWith() does) in order to prevent loading from the memory address of the constant instead of loading the cons...

I am sorry I don't understand. Are you suggesting calling replaceAllUses of the .str1? What I really want to do is to 'erase' the function. By erasing I'd expect the uses of .str1 to 0 (because in the example I have it is used only by f()) and I see they are not. Vassil > &gt...
