Add optimize_full qmake config option This patch adds a new config option to qmake to enable full optimization where it makes sense. This currently is supported on all gcc like compilers by exchanging -O2 for -O3. In qtbase it is used to enable full optimizations on qtcore and qtgui and in a later patch can be used to replace similar existing logic in QtWebKit's WTF and JavaScriptCore modules. This fixes a performance regression from gcc 4.7 to 4.8 in the software renderer. An aliasing error in qregion.cpp which was exposed by more aggresive optimization has been solved as well.

Clang on Linux also needs this, but it has no equivalent flag, so enabling LTCG for Clang on static libraries will result in linker error. This commit does not add support for enabling it in configure. It can be enabled on a per-project basis by doing CONFIG += ltcg or by passing -config ltcg to qmake's command-line.

Move the SSE2/AVX/Neon/etc. flags into the compiler mkspecs This allows us to have different flags for the compilers for supporting the same feature. For example, the official flag in GCC to support AVX2 is -mavx2, but ICC does not support it (yet), requiring -march=core-avx2 or -xCORE-AVX2. That flag, instead, enables support for all the features that the "Core-AVX2" processor (codename Haswell) will support. And clearly, the MSVC flags are different.

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>

Clean up ltcg.prf with variables, including a new static mode By using the special "ar" and "ranlib" tools, the symbol table is made visible, so we don't need fat LTO binaries. Since we need to store the new tool names, we may as well clean up ltcg.prf with variable names for the fat mode too.
