PROPACK contains several files with compiler directives that do not compile with flang (built at LLVM commit 748922b).

Example:

$ ~/p/llvm-project/build/bin/flang-new -c ./complex8/Examples/matvec.F
error: Could not parse ./complex8/Examples/matvec.F
././complex8/Examples/matvec.F:160:17: error: expected end of line
  CDIR$ LOOP COUNT(10000)
                  ^
././complex8/Examples/matvec.F:160:1: in the context: execution part construct
  CDIR$ LOOP COUNT(10000)
...

gfortran compiles this file successfully. It's fine not to support the compiler directive, but being able to parse it and ignore it would be helpful.
