Insert CallInst within a function passing same parameters of the calling function.
Hi,
supposing I have a function “foo” like the following:
int foo(int a, int b) {
...
...
}
I want to insert int the LLVM IR a call instructions to a function “bar” that requires the same parameters of foo.
So my function foo will become:
int foo(int a, int b) {
bar(a,b);
…
...
}
I am using the following code:
bool ThreadSanitizer::runOnFunction(Function &F) {

[LLVMdev] Accessing a function's arguments
I am trying to generate a simple wrapper function:
Function* pWrapper = m_module.getOrInsertFunction(name,
FunctionType::get(Type::VoidTy,
vector<const Type*>(1, PointerType::get(Type::IntTy)), false));
How do I actually get the Value* for the one argument to this function?
The pWrapper->getArgumentList().size() is 0. Shouldn't the argument list
contain the Value*

Problem about API difference between LLVM3.5 and LLVM3.9
Hi all,
Recently I have implemented a transformation pass based on LLVM3.5 and its
function is to duplicate the function's argument list in a bytecode file
and replace all use of original function with modified function. In
LLVM3.5, the pass can work properly. However, when I tried to transplant
the pass to LLVM3.9, the error "Argument value does not match function
argument type!"

get function parameters (not arguments)
Sorry i'm using the following code:
F = (cast<CallInst>(BI))->getCalledFunction();
for (auto& A : F->getArgumentList()) {
errs() << "------- " << A.getName() << " " << "11" <<
"\n";
}
But how can I get the parameters (as e and f in the example)?
Thank you and best,

[LLVMdev] Making Constants from GenericValues
I'm trying to turn some GenericValues into Constants in the interpreter
using code like this, in a switch statement:
case Type::IntTyID:
SI = ConstantSInt::get(FB->getType(), ArgVals[i].IntVal);
params.push_back(UI);
UI->dump(); //for testing
break;
FB is a Function::ArgumentListType::iterator
ArgVals is a std::vector<GenericValue>

[LLVMdev] Function::getArgumentList() question
Hi folks --
The comments in Function.h for Function::getArgumentList() state that the argument list is empty for external functions. This entails (I think) that it is not possible to determine the contents of the argument list of functions for which LLVM has only seen a forward declaration, for a given compilation unit. Is this correct?
If this is the case, is there any way around this?

[LLVMdev] correct types for ArgumentList?
I'm trying to create and insert a anonymous function that will make a
assignment on a GlobalVariable, based on a existing StoreInst. Once I
find this StoreInst(which provides me with 2 Value* objects for me to
use) I need to pass it to my anonymous function so it can carry out
the assignment. I can not get the correct types, at runtime I get a
bad signature error.
So basically the function is

[LLVMdev] 'opt' Aborted "While deleting: void %"
Hey everyone,
So I have an LLVM pass that appears to run completely and work fine, and
then it aborts at the very end. When exiting the final runOnFunction call,
I get the following error / stack dump. I cannot figure out why this is
happening for the life of me - does anyone have any ideas? I'm not trying
to do any crazy deallocation or anything, it just seems like a normal pass
to me.

[LLVMdev] 'opt' Aborted "While deleting: void %"
Hi Griffin, did your pass create a data structure that holds values somehow,
and forgot to delete it? Also, try running under valgrind in case this is
due to a memory error of some kind.
Ciao, Duncan.

[LLVMdev] Adding type qualifies or property
Hi
Has anybody tell me how to create some new type qualifies in LVM?
A type qualify, like "const" in C, is useful for program
analysis. I hope that I can set/get the type qualify of any value
in a program analysed.
Or, if I could add a property to the value class and set/get the
property, it is same to add some new type qualifies. So, I simply
insert a "int" private

[LLVMdev] 'opt' Aborted "While deleting: void %"
Using Valgrind hasn't shown me anything terribly unusual. And I'm confused
because its not even trying to delete a real instruction; deleting a void
type with no name? That doesn't make any sense...
Any other hints? I've seen a few posts in the past about this relating to
some internal LLVM bugs...

I really, really, really need your help. This is my third email now,
please don't ignore me! I understand this must be a trivial thing, but
I've ground to a halt, and REALLY need some guidance. Please see below for

desperate here.

Yes, it is a pass.
Here is a very general overview of the file structure as far as the AA is
concerned. LLVM is not my strong-suit, I do hardware simulators, not
compilers.
