<pre>I didn't root cause the issue. However, the current 'main' branch Passes seems
broken.
To reproduce, git clone current main branch. Build it, and create any sample C
program. Like:
int foo() {
return 0;
}
int main() {
foo();
return 0;
}
and then run:
```
$ ./bin/clang -c -emit-llvm sample.c
$ ./bin/opt -load ./lib/LLVMHello.so -hello < sample.bc
./bin/opt: unknown pass name 'hello'
```
This will happen for any Pass we create too, and that's how I noticed it.
This works fine, if instead of the main branch, we download and build for
example the latest release candidate llvm-project-llvmorg-12.0.0-rc3.tar.gz
source.
The expected behavior would be:
```
$ ./bin/opt -load ./lib/LLVMHello.so -hello < sample.bc
Hello: foo
Hello: main
```
Thank you.</pre>
