LLVM 3.8 change in function argument lists?
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 *arg1 = &(*argiter);
arg1->setName("obj");
As far as I can tell the first vers...

[LLVMdev] Adding function call in LLVM IR using IRBuilder causes assertion error
...guments and pass
them as explained in the tutorial.
My code is (this function is supposed to add a call to f in bb at pos):
void addCallSite(Function *f, BasicBlock *bb, BasicBlock::iterator pos) {
std::vector<Value*> args;
IRBuilder<> builder(bb,pos);
for(Function::arg_iterator argit =
f->arg_begin();argit!=f->arg_end();argit++){
AllocaInst* allocInst = builder.CreateAlloca(argit->getType());
args.push_back(allocInst);
}
builder.CreateCall(f,args.begin(),args.end());
}
This seems to work for functions without parameters (eg. int foo()), but
once a fu...

[LLVMdev] Adding function call in LLVM IR using IRBuilder causes assertion error
...space on the stack.
Suppossing that the function parameters simple enough, like integral or
floating point types, and the "default value" is zero, something like
this will do (untested):
std::vector<Value*> args;
IRBuilder<> builder(bb,pos);
for(Function::arg_iterator argit =
f->arg_begin();argit!=f->arg_end();
argit++)
{
Value *arg = Constant::getNullValue(argit->getType());
args.push_back(arg);
}
builder.CreateCall(f,args.begin(),args.end());
If your arguments are something more fancy, you have more work ahead
