Hi,
I wrote a sample program to iterate through each function and just print a ‘hello’ for every basic blocks. There were no errors while running a ‘make’ command. But the program returns some errors in my system. When I check the same program in my friend’s system it works fine.
My program:
virtual bool runOnFunction(Function &F) {
for (Function::iterator b = F.begin(), be = F.end(); b != be; ++b) //Thorws error when I add this loop
{
errs()<<“hello”<<“\t”;
}
return false;
}
Command : $ opt -load ~/LLVM/bulid/Debug+Asserts/lib/CSE.so -CSE < hell.ll > /dev/null
Error while running the pass :
hello hello 0 opt 0x00000000014a1b92 llvm::sys::PrintStackTrace(_IO_FILE*) + 34

Any help regarding the error.
