Thanks for your reply, John.
I am using opt to run my pass. Should opt by default link in the library?
Would you please give me some idea on fixing it? Thanks!
opt -load ../../../Debug+Asserts/lib/LLVMHello.dylib -hello < hello.bc >
/dev/null
My pass is just:
#include "llvm/IR/Function.h"
#include "llvm/Pass.h"
#include "llvm/Support/raw_ostream.h"
#include "llvm/Analysis/Dominators.h"
using namespace llvm;
namespace {
struct Hello : public FunctionPass {
static char ID;
Hello() : FunctionPass(ID) { }
virtual void getAnalysisUsage(AnalysisUsage &AU) const {
AU.addRequired<DominatorTree>();
}
virtual bool runOnFunction(Function &F) {
DominatorTree& DT = getAnalysis<DominatorTree>();
BasicBlock* BB = DT.getRoot();
return false;
}
};
}
char Hello::ID = 0;
static RegisterPass<Hello> Z("hello", "My test
analysis", true, true);

Thanks!Odd. I would think that opt would have that pass linked in statically. I'm not sure why it's not working.

[LLVMdev] Runtime exception in DominatorTree.getRootNode()
Hi Weibo, I thought would be more efficient discussing here (I just saw that every info was replicated on both emails you were sending to me). I just run your example here on my working machine, and I didn't have any issues with the namespace. Just tell me one thing: which line (and flags) are you using when configuring and make your build llvm directory? Oh, and one more thing: what is on your $PATH?
