[LLVMdev] convert a char * to a value

[Nabila ABDESSAIED]

Hi all,

Please i need help, I have a method that takes 2 arguments with type char *:
void branchPredict(char *b1, char *b2){
---
--
}
i'm supposed to add this method, in an IR basic bloc:
to add it into a basic bloc i do:

//i: is the basic bloc
std::vector<Value*> void_43_params;
Constant* tbname = ConstantArray::get(M.getContext(),i->getNameStr() ,
true);
Constant* pbname = ConstantArray::get(M.getContext(),
 i->getPrevNode()->getNameStr(), true);
void_43_params.push_back(tbname);
void_43_params.push_back(pbname);
CallInst* void_43 = CallInst::Create(func_branchPredict,
void_43_params.begin(), void_43_params.end(), "", i->getTerminator());

when i execute the pass (opt -load ....)  i get an error:


Call parameter type does not match function signature!
[3 x i8] c"bb\00"
 i8*  call void @branchPredict([3 x i8] c"bb\00", [4 x i8] c"bb1\00")
Call parameter type does not match function signature!
[4 x i8] c"bb5\00"

Broken module found, compilation aborted!

Stack dump:

2. Running pass 'Module Verifier' on function '@main'

Any help
thanks
