-> [Running a pass with opt](https://llvm.org/docs/WritingAnLLVMPass.html#id9)
I run
```
opt -load lib/LLVMHello.so -hello -time-passes < hello.bc > /dev/null
```
But it shows
```
The `opt -passname` syntax for the new pass manager is not supported, please use `opt -passes=<pipeline>` (or the `-p` alias for a more concise version).
See https://llvm.org/docs/NewPassManager.html#invoking-opt for more details on the pass pipeline syntax.
