Fix '=' alignment and replace tabs in *.conf (whitespace only change) 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() Change-Id: I1d2870d0a2fe2e30d398c140fe523e69dd20c81b Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@digia.com>

Remove automated generation of dwarf index 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.

Add QMAKE_NM to the mkspecs 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.

eglfs: rework hooks design There are two problems with the current design: 1. if (hooks) hooks->foo() doesn't work in debug mode when no platform hook is defined. The problem doesn't arise in release mode because the compiler optimizes away the if (hooks) into a no-op since hooks is NULL when no platform hook is defined. 2. Adding a new hook requires changing every platform's hook implementation. New approach: 1. Define QEglFSHooks as a class with virtual functions. A stub file provides the default implementation. 2. Platform hooks derive from above class and reimplement whatever is needed. The filenames and variables have been changed to be more in line with the Qt style.

eglfs: Introduce hooks for the eglfs plugin EGL provides an api to create a rendering context for khronos APIs on native surfaces. The board initialization and window creation is platform specific. This commit adds platform hooks/extensions to the EGLFS plugin and implements them for the Amlogic 8726M. The hook interface is internal and there are no ABI/API guarantees. EGLFS is now linked with -Wl,-no-undefined to make sure that a hook does not add unresolvable symbols.
