The following code is causing an "UNREACHABLE executed!" and a stack dump,
any ideas?
namespace {
struct myPass : public CallGraphSCCPass {
static char ID;
myPass() : CallGraphSCCPass(ID) {}
virtual void getAnalysisUsage(AnalysisUsage &AU) const {
AU.setPreservesAll();
AU.addRequired<LoopInfo>();
}
virtual bool runOnSCC(CallGraphSCC &SCC) {
for (CallGraphSCC::iterator CGNodeItr = SCC.begin(),
CFNodeItrE=SCC.end();CGNodeItr!=CGNodeItrE;++CGNodeItr) }
const CallGraphNode *CGNode = *CGNodeItr;
Function *F = CGNode->getFunction();
if (!F->isDeclaration())
LoopInfo &LI = getAnalysis<LoopInfo>(*F);
}
return false;
}
};
char myPass::ID = 0;
static RegisterPass<myPass> X("myPass", "This is my pass", false, false);
}
