[LLVMdev] Problem with variable argument intrinsics

[aditya vishnubhotla]

Hi,
I tried creating variable argument  intrinsics which
are to be placeholders for some instructions which
should not be executed by the backend.

Kindly help me with the errors in my "migrate_begin"
intrinsic creation

//Additions made to Intrinsics.td file:

def llvm_migrate_begin : LLVMType<iAny>;
def int_migrate_begin :
Intrinsic<[llvm_migrate_begin,llvm_vararg_ty],[IntrWriteMem],"llvm.migrate_begin">;

//A section of the code which deals with the
//"migrate_begin" intrinsic creation is as follows:

const Type **Tys=(const
Type**)calloc(extTys.size(),sizeof(Type*));     /*
extTys 
vector contains data types(pointers) of formal
parameters  of the 
function "f" */ 
int i=0;
for(vector<const Type*>::iterator
it=extTys.begin(),e=extTys.end();it!=e;it++)
        {Tys[i++]=*it;}
extTys.clear();
Module *M = bbp->getParent()->getParent();
Function *f =
Intrinsic::getDeclaration(M,Intrinsic::migrate_begin,Tys,i);
/* 
migrate_begin intrinsic creation */
CallInst* CI = new CallInst(f,"migrate_begin",bbp);   
 /*bbp is pointer to basic block where 
intrinsic is to be inserted*/


//Errors:

Overloaded intrinsic has incorrect suffix: '.i32.i32'.
It should be '.i32'
i32 (...)* @llvm.migrate_begin.i32.i32

Overloaded intrinsic has incorrect suffix:
'.i32.i32.i32'. It should be '.i32'
i32 (...)* @llvm.migrate_begin.i32.i32.i32

Broken module found, compilation aborted!
