Thanks for have a look. Two things are user-visible in this PR. Constants can now be printed in a debugger, and a constant is only described where its defining unit is compiled, so constants of an intrinsic module such as iso_fortran_env are still not described. I have added an entry covering both to flang/docs/ReleaseNotes.md, which is where the compressed-DWARF change from this cycle is also noted.
