Test each include file directly, instead of doing a large #include. This
verifies that each header is compilable on its own. One big advantage of
doing it via a special compiler in qmake is that we skip pre-compiled
headers, which has hidden build errors in the past.
This solution is implemented by making syncqt produce a second list of
headers. This list is the same as the list of headers in the source
code to be installed, minus the headers that declare themselves to be
unclean, via the pragma:
#pragma qt_sync_skip_header_check
This mechanism is applied only for public libraries (skipping
QtPlatformSupport, an internal_module).
This test is enabled only for -developer-builds of Qt because it
increases the compilation time.
On QtTest: the library only links to QtCore, but it has two headers that
provide inline-only functionality by including QtGui and QtWidgets
headers (namely, qtest_gui.h and qtest_widget.h). If those two modules
aren't getting compiled due to -no-gui or -no-widgets to configure, we
need to remove the respective headers from the list of headers to be
checked. If they are being built, then we need to make QtTest's build
wait for the headers to be generated and that happens when qmake is
first run inside the src/gui and src/widgets directories.

You can configure with -no-libproxy to avoid the dependency.
It will not be used on OS X or Windows, as we already implement
the native API for getting proxies there.
Currently we use whatever PAC runner is provided by the distro
for running PAC scripts - if we want to run PAC scripts using
Qt, then we would have to implement a pacrunner plugin to libproxy.
Note that their webkit pacrunner is using javascriptcore already.
Tested using the libproxy 0.4.7 that is included in Ubuntu 12.04.
Re-tested using Ubuntu 14.04 which ships libproxy 0.4.11.
It works except when both socks and http proxies are configured in
the manual settings - in that case libproxy returns only the socks
proxy. This seems to be covered by libproxy issue 119.

moot. We removed the detection previously because we couldn't
automatically enable Neon due to leakage of instructions outside the
areas protected at runtime.
Instead, we rely on the mkspec properly passing the necessary flags that
enable Neon support.
This commit does not change that. All it does is verify whether the arch
detection found "neon" as part of the target CPU features. In other
words, it moves the test that was in simd.prf to configure.
It does fix the Neon detection in configure.exe, which was always

GCC 4.9 now allows us to #include any and all intrinsics headers, not
just the one for which we're compiling code, a behavior that ICC and
MSVC have had for some time. With that, we're able to have the functions
for different targets in the same source file. See the GCC manual:
http://gcc.gnu.org/onlinedocs/gcc/Function-Multiversioning.html
This functionality is notified by the QT_COMPILER_SUPPORTS_HERE(XXX)
macro, which indicates that all the intrinsics from
QT_COMPILER_SUPPORTS_xxx are available and enabled. To complement, a
QT_COMPILER_SUPPORTS(XXX) macro is also added.
Unlike ICC and MSVC, GCC requires a special function attribute, which
will also cause code optimization. That's the QT_FUNCTION_TARGET macro.
Note: because of the absence of the target attribute, ICC and MSVC will
not generate instructions with the VEX prefix unless they only exist
with the VEX prefix or if -mavx / -arch:AVX are enabled.

Do not link against ICU on Windows, unless it is explicitly requested

if ICU was detected in the configure environment.
So far ICU has been used in Qt Core for
- support of a larger set of codecs (805 instead of 135)
- more accurate QLocale functionality (QLocale::toUpper,
qLocale::toLower)
- string collation
However, for all functionality there are also backends using the
Windows API/Registry (QLocale, QCollator), or built-in
codecs that are part of QtCore. Since the ICU dependency is quite heavy
(3 libs with about 25 MB) it seems sensible to not require it by default.
QtWebkit is unaffected, since it has it's own ICU check.

The patch introduces a new build configuration on Windows which
can be requested by passing -opengl dynamic to configure.
Platforms other than Windows (including WinRT) are not affected.
The existing Angle and desktop configurations are not affected.
These continue to function as before and Angle remains the default.
In the future, when all modules have added support for the dynamic
path, as described below, the default configuration could be changed
to be the dynamic one. This would allow providing a single set of
binaries in the official builds instead of the current two.
When requesting dynamic GL, Angle is built but QT_OPENGL_ES[_2] are
never defined. Instead, the code path that has traditionally been
desktop GL only becomes the dynamic path that has to do runtime
checks. Qt modules and applications are not linked to opengl32.dll or
libegl/glesv2.dll in this case. Instead, QtGui exports all necessary
egl/egl/gl functions which will, under the hood, forward all requests
to a dynamically loaded EGL/WGL/GL implementation.
Porting guide (better said, changes needed to prepare your code to
work with dynamic GL builds when the fallback to Angle is utilized):
1. In !QT_OPENGL_ES[_2] code branches use QOpenGLFunctions::isES() to
differentiate between desktop and ES where needed. Keep in mind that
it is the desktop GL header (plus qopenglext.h) that is included,
not the GLES one.
QtGui's proxy will handle some differences, for example calling
glClearDepth will route to glClearDepthf when needed. The built-in
eglGetProcAddress is able to retrieve pointers for standard GLES2
functions too so code resolving OpenGL 2 functions will function
in any case.
2. QT_CONFIG will contain "opengl" and "dynamicgl" in dynamic builds,
but never "angle" or "opengles2".
3. The preprocessor define QT_OPENGL_DYNAMIC is also available in
dynamic builds. The usage of this is strongly discouraged and should
not be needed anywhere except for QtGui and the platform plugin.
4. Code in need of the library handle can use
QOpenGLFunctions::platformGLHandle().
The decision on which library to load is currently based on a simple
test that creates a dummy window/context and tries to resolve an
OpenGL 2 function. If this fails, it goes for Angle. This seems to work
well on Win7 PCs for example that do not have proper graphics drivers
providing OpenGL installed but are D3D9 capable using the default drivers.
Setting QT_OPENGL to desktop or angle skips the test and forces
usage of the given GL. There are also two new application attributes
that could be used for the same purpose.
If Angle is requested but the libraries are not present, desktop is
tried. If desktop is requested, or if angle is requested but nothing
works, the EGL/WGL functions will still be callable but will return 0.
This conveniently means that eglInitialize() and such will report a failure.
Debug messages can be enabled by setting QT_OPENGLPROXY_DEBUG. This will
tell which implementation is chosen.
The textures example application is ported to OpenGL 2, the GL 1
code path is removed.
[ChangeLog][QtGui] Qt builds on Windows can now be configured for
dynamic loading of the OpenGL implementation. This can be requested
by passing -opengl dynamic to configure. In this mode no modules will
link to opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will
dynamically choose between desktop and Angle during the first GL/EGL/WGL
call. This allows deploying applications with a single set of Qt libraries
with the ability of transparently falling back to Angle in case the
opengl32.dll is not suitable, due to missing graphics drivers for example.
