  |     [PATCH] gdb/corelow: mark bytes unavailable when reading from unavailable mapping
  |     
  |     The main motivation for this change is to nicely support "lightweight"
  |     core files on ROCm (more on this below), but I think that the change
  |     also makes sense for regular core files.
  | ... 60 lines of the commit log omitted.
  | ... applied on top of baseline commit:
  | c2bf7de1eb7 xcofflink buffer overflows

Produces 3 regressions:

  | FAIL: gdb.debuginfod/corefile-mapped-file.exp: check value of pointer is unavailable with library file missing
  | FAIL: gdb.debuginfod/corefile-mapped-file.exp: check value of pointer is unavailable with wrong library in place
