[Valgrind-users] Cannot get a simple pass-through tool

[Felix R. <fe...@kn...>]

Hi everybody

    I am trying to make a simple pass-through tool, in which BB's are 
just copied. I am using valgrind 3.13.0, and this is the code I have in 
my tool. Can somebody give me a hand?

Thank you!
Felix

static IRSB *my_instrument (VgCallbackClosure *closure, IRSB *bbIn, 
const VexGuestLayout *layout, const VexGuestExtents *vge, const 
VexArchInfo * vai, const IRType gWordTy, IRType hWordTy)
{
    IRSB *bbOut = emptyIRSB ();
    bbOut->tyenv = deepCopyIRTypeEnv (bbIn->tyenv);
    bbOut->next = deepCopyIRExpr (bbIn->next);
    bbOut->jumpkind = bbIn->jumpkind;

    for (Int i = 0; i < bbIn->stmts_used; ++i)
    {
       IRStmt* const st = bbIn->stmts[i];
       addStmtToIRSB(bbOut, st);
    }
    return bbOut;

}
