llvm dev - Jul 2013 - [LLVMdev] LLVM ERROR : Invalid instruction

#include <string>
#include <string.h>
#include <iostream>
#include <stdio.h>
using namespace std;

void foo(string str)
{
}
int main()
{
string str="aa";
foo(str);
return 0;
}

1. clang++ -c -emit-llvm foo.cpp -o foo.ll
2. llc -march=cpp -o foo.ll.cpp foo.ll   (at the execution of this command
its giving an error as "Invalid Instruction")

May I know why is it failing on step 2. ???

Looks like the CPP backend doesn’t know how to deal with exception handling.
It’s complaining that it can’t handle a landingpad instruction.
