Bug ID: 19585
Summary: missed opportunity to speed up symbol reading
Product: gdb
Version: unknown
Status: NEW
Severity: normal
Priority: P2
Component: symtab
Assignee: unassigned at sourceware dot org
Reporter: tromey at sourceware dot org
Target Milestone: ---
I've been debugging recently where I run firefox and attach to it.
I simply reattach each time from the same gdb.
(I would re-run, but this isn't really possible in the scenario
I'm debugging.)
In this situation, each time I attach, gdb reads the debug info for
all the shared libraries used by the new inferior. However, it just
discarded all that same data.
This could be made more efficient by noticing this situation and
just re-using the same objfiles, relocating them as necessary.
This would be significantly nicer for me as reading libxul is ~10
seconds, a very noticeable hiccup during development.
