include(gcc-base.conf)
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>

rpath: use new DTAGS if available this allows LD_LIBRARY_PATH to take precedence over the hard-coded rpath, which is the only sane thing to do (which is also why i'm not adding an option to disable it). this behavior is consistent with non-linux systems. the windows version has no auto-detection, just like for gold linker usage.

QMAKE_LFLAGS_USE_BFD = -fuse-ld=bfd
Introduce qmake feature use_gold_linker This patch adds the feature use_gold_linker to use the gold linker that has been part of of GNU binutils since 2008. Gold links C++ libraries much faster and use less memory. The feature is autodetected when building Qt on Linux, but can be disabled in configure. On MingW builds it is default off but can be enabled for cross builds.

Add a linker version script to Qt libraries This linker script is only enabled for systems with GCC or GCC-like compilers, though technically it should work on the BSDs too (will enable after testing). For regular modules, this declares one ELF version "Qt_5" and places all QtCore symbols inside, then it declares unused ELF versions "Qt_5.x" for each older minor release. For modules declared "internal_module", all symbols are placed in version Qt_5_PRIVATE_API. The big advantage of an ELF version is that, when we do Qt 6, both versions of QtCore could be loaded in memory without conflicts and all symbols would be resolved to the correct library. No module can talk to both at the same time, but this avoids mistakes of loading them indirectly by plugins. The extra Qt_5.x versions will be used in the next commit.
