The index is only helpful if the version of GDB to
create it uses the same version as the GDB version
that consumes it. Outside the "local development"
scenario this happens only by conincidence, still
we add ~3.6% to the debug library size and face
maintenance issues like QTBUG-34950.
We also don't see the same performance benefit anymore
with recent versions as we did when the feature was
added, so it's best to not create the index anymore.
People who need it, still can add it manually, or
by the 'gdb-add-index' tool that comes with recent
versions of GDB, or trust their distributors to
set up indexes matching their runtime environment.

We'll use nm to get the listing of symbols in the next commit.
The -P option is "portable", which sounds like a good idea. I don't
have access to any of the commercial Unix systems, but I do remember
them printing a different format than GNU binutils's nm.

Replace all tabs with proper space characters and consistently align
the '=' characters. The default alignment for the '=' of 25 characters
has been left as is to get a minimal diff. Lines with the '=' further
to the right and those belonging to 'proper code (TM)' have not been
touched.
The work was mostly done using the following python script (might
come in handy again...):
import sys, re
indent_eq = 25 + 0*4 # 25 characters was the most widely used indentation for the '=' character
p = re.compile(r'(\w+)[ \t]*([\-\+]?)(=$|= )[ \t]*(.*$)')
for fn in sys.argv[1:]:
with open(fn, 'r+') as f:
lines = []
nl_count = 0
continuity_indent = None
for l in f:
m = p.match(l)
nl = l
if m:
n_spaces = max(m.start(3), indent_eq - 1) - len(m.group(2)) - len(m.group(1))
if m.group(2) and m.start(2) >= indent_eq-1 and m.start(2) % 4 == 0:
n_spaces -= 1 # left-shift '+=' by one if the '+' is aligned to a multiple of 4
n_spaces = max(1, n_spaces) # we want at least one space before '='/'+='
nl = m.group(1) + ' '*n_spaces + ''.join(m.group(2,3,4)) + '\n'
continuity_indent = nl.find('= ') + 2 if l[-2] == '\\' else None # remember indent on '\\$'
elif continuity_indent:
nl = ' '*continuity_indent + l.lstrip()
if l[-2] != '\\': # check when to stop the continuation
continuity_indent = None
elif l.startswith('#'):
nl = l.expandtabs(2)
if l != nl:
nl_count += 1
lines.append(nl)
if nl_count > 0:
print fn, nl_count, len(lines)
f.seek(0)
f.writelines(lines)
f.truncate()
