Bug ID: 15883
Summary: reread_symbols: preserving section offsets?
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: symtab
Assignee: unassigned at sourceware dot org
Reporter: dje at google dot com
reread_symbols preserves section offsets across rereading the bfd.
/* Save the offsets, we will nuke them with the rest of the
objfile_obstack. */
num_offsets = objfile->num_sections;
offsets = ((struct section_offsets *)
alloca (SIZEOF_N_SECTION_OFFSETS (num_offsets)));
memcpy (offsets, objfile->section_offsets,
SIZEOF_N_SECTION_OFFSETS (num_offsets));
...
/* We use the same section offsets as from last time. I'm not
sure whether that is always correct for shared libraries. */
objfile->section_offsets = (struct section_offsets *)
obstack_alloc (&objfile->objfile_obstack,
SIZEOF_N_SECTION_OFFSETS (num_offsets));
memcpy (objfile->section_offsets, offsets,
SIZEOF_N_SECTION_OFFSETS (num_offsets));
objfile->num_sections = num_offsets;
What if in recompiling the user added a new section?
Seems like this won't work.
