             Bug #: 15376
           Summary: IWBN to allocate more Fission objects on
                    comp_unit_obstack instead of objfile_obstack
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
        AssignedTo: unassigned@sourceware.org
        ReportedBy: dje@google.com
    Classification: Unclassified


Filing this away for future reference.
[Since FIXMEs in the code are generally frowned on, sigh.]

Some of the Fission data structures in dwarf2read.c could live on
comp_unit_obstack instead of objfile_obstack.
Some are easier than others (e.g. struct dwo_unit when using DWP files).

Fission:
