Hi John!!

Yes, I only write one Pass (Function Pass) and gave it that one name.

Yes, I'm sure. I wrote the Pass and the RegisterPass also in a .cpp file,
like this:
#include<vector>
#include"llvm/Pass.h"
#include"llvm/Function.h"
#include"llvm/BasicBlock.h"
#include"llvm/Instruction.h"
#include"../blockNrs/blockNrs.h"
#include"GenomManager.h"
using namespace std;
using namespace llvm;
namespace {
class FunctionAnalysis : public FunctionPass
{
public:
static char ID;
FunctionAnalysis() : FunctionPass((intptr_t)&ID) {} // Konstruktor ruft
Funktionsdurchlauf auf
~FunctionAnalysis() {}
virtual void getAnalysisUsage(AnalysisUsage &AU) const {
AU.setPreservesAll();
AU.addRequired<blockNrs>();
};
virtual bool runOnFunction(Function &F) // F is a pointer to a
Function instance
{
GenomManager *GGenomManager;
GGenomManager=new GenomManager();
blockNrs &bnrs=getAnalysis<blockNrs>();
GGenomManager->newFunction(F);
for(Function::iterator b = F.begin(), be = F.end(); b!=be; ++b)
{
//aktuelle Block Nummer wird geholt
blockCounter *bcntr = bnrs.lookup(b);
GGenomManager->newBlock(&(*b),*bcntr);
for(BasicBlock::iterator i = b->begin(), ie = b->end();
i!=ie; ++i)
{
GGenomManager->newInstruction(i);
}// end for BB
} // end for Function
return false;
} // end runOnFunction
private:
};// end class
char FunctionAnalysis::ID = 0;
RegisterPass<FunctionAnalysis> X("gasched", "GA Scheduling
Pass");
} // end namespace
Could it be that I did something wrong in the Makefile of the source code? The
source code itself is compilable. The Error Message occurred when I tried to
test it ("opt -load" its .so file ) .
Thanks a lot...
