            Bug ID: 25435
           Summary: Tab completion of symbols is not always instant
           Product: gdb
           Version: 8.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cli
          Assignee: unassigned at sourceware dot org
          Reporter: tblodt at icloud dot com
  Target Milestone: ---

In binaries with many symbols, tab completion of symbols for the "break"
command can take a few seconds. The symbols should ideally be stored in some
kind of sorted data structure that allows binary searching to return results
with no noticeable delay.

I've been running into this with Chromium. You can reproduce by building
Chromium with the default settings, loading the binary into gdb, and trying to
use "break" tab completion.
