The bytecode is not interleaved in the generated assembly any more (I don't know which flag sets this) and the -XX:PrintAssemblyOptions=intel flag no longer seems to work.  I also tried this on a non-Graal benchmark run, and it had the same problem.  Perhaps something wrong in 13?

This sounds like the following bug which is not yet fixed in any EA build:

The problem was introduced in JDK 13 build 22.
