7ff3032b22 unify windows mkspecs: define c++ flags explicitly
with 40e87491 merged, 'QMAKE_CXXFLAGS' variable in
'win32-g++' toolchain became defined via 'QMAKE_CFLAGS'.
the similar can be found in 'win32-clang-msvc' and
'win32-icc' toolchains too.

this works for now, because such definitions just duplicates code
from includes, like 'gcc-base.conf', 'msvc-desktop.conf', etc.
but it would became broken, if changes would be applied to
'QMAKE_CXXFLAGS' definitions in that includes, prior
to the redefinitions in 'win32-*/qmake.conf' toolchains.

thus 'QMAKE_CXXFLAGS' definitions in 'win32-*/qmake.conf' toolchains
should not depend on 'QMAKE_CFLAGS' and be done explicitly.

in order to apply this change correctly to 'win32-icc' toolchain,
its 'QMAKE_CFLAGS' variable should become dependent on definitions
in the includes, similar to 'win32-clang-msvc' and
'win32-msvc' toolchains.

940fd1734b unify windows mkspecs: move angle/vulkan includes
'win32-icc' toolchain:
- remove duplicated angle/vulkan includes.

'win32-g++' toolchain:
- place angle/vulkan includes before the unrelated compiler-related
  variable re-definitions, similarly to the 'win32-clang-msvc',
  'win32-icc', and 'win32-msvc' mkspecs.

40e8749188 unify windows mkspecs: update definitions
mingw-w64 toolchain:
- add missing compiler definitions, similar to
  'msvc-desktop.conf' toolchain,
- describe the reasons of missing compiler definitions, available in
  'msvc-desktop.conf' toolchain,
- add missing 'QMAKE_CXXFLAGS' and 'QMAKE_CXXFLAGS_WARN_ON' variables,
  similar to 'msvc-desktop.conf' toolchain.

ICC on Windows toolchain:
- add 'QMAKE_CFLAGS_OPTIMIZE_FULL' variable, similar to 'gcc-base.conf'
  toolchain, though left it unused for now,
- add missing flags to 'QMAKE_CFLAGS' variable, similar to
  'msvc-desktop.conf' toolchain,
- update deprecated 'Qwd' flag with 'Qdiag-disable',
- use 'QMAKE_CFLAGS_OPTIMIZE_DEBUG' variable instead of '-Od' flag,
  similar to 'gcc-base.conf' toolchain (ICC implies '-O2' optimization
  level by default, while MSVC implies '-Od'),
- add 'QMAKE_CFLAGS_UTF8_SOURCE' variable, similar to
  'msvc-version.conf' toolchain; use a workaround to initialize it,
  until '-utf-8' flag would be supported by ICC on Windows,
- update deprecated '-Qstd=c++1z' flag with '-Qstd=c++17',

MSVC toolchain:
- remove 'incremental' from MSVC 'CONFIG' variable, since it has
  relevance only for the Unix generator,
- add 'QMAKE_CFLAGS_OPTIMIZE_DEBUG' variable, used in ICC for Windows
  toolchain,
- add empty 'QMAKE_LIBS' variable, similar to 'win32-g++' toolchain,
- add 'uuid.lib' library to 'QMAKE_LIBS_GUI' variable, similar to
  'win32-g++' toolchain,
- add C++14 and C++17 language support flags, though left them disabled

eef2d1af33 unify windows mkspecs: reorder variables and flags
Common changes to mingw-w64, ICC on Windows, and MSVC toolchains:
- set similar order of variables and its splitting into sections,
- set similar order of flags in variables and the way they are set.

mingw-w64 toolchain:
- move 'gcc-base.conf' include before setting Windows specific
  flags, similar to include 'msvc-desktop.conf' in ICC on Windows
  toolchain; this leads to consistency with other toolchains
  and allows to safely override common GCC variables with Windows
  specific ones, when needed,
- move 'QMAKE_EXT_OBJ' and 'QMAKE_EXT_RES' variables to the linker
  flags section, according to its purpose.

MSVC toolchain:
- set flags order in 'CONFIG' variable, similar to mingw-w64 toolchain.

As Qt applications using OpenGL are linked against these libs, merging
them into QtANGLE by default (780105f906)
was a binary incompatible change. This change restores the default
behavior to the one before given change.

If the user wants the libraries to be merged, he can pass
combined-angle-lib to configure.

280e321e52 Fix detection of F16C for the Intel compiler (again) and Visual Studio
Neither the Intel compiler nor Visual C++ have a dedicated switch to
enable F16C support, like GCC and Clang do. So we used the AVX switch
for that in commit 8241d51f70, as it was
the closest, lowest denominator. That was incorrect and insufficient.

The Intel compiler silently miscompiles the intrinsics with -xAVX,
making calls to out-of-line functions like _mm_cvtps_ph, which don't
exist. So we actually have to use AVX2 support to generate correct code.
That might be a problem later, since Ivy Bridge supports F16C but not
AVX2.

Visual C++ is able to generate F16C code with just -arch:AVX.

Either way, since there's no dedicated command-line switch, there's also
no dedicated preprocessor macro. We're using __AVX2__ for both
compilers, as that's a sufficient condition to indicate a processor that
supports F16C.

8241d51f70 x86: Detect F16C with the Intel compiler too
The .pro file requires the QMAKE_CFLAGS_F16C to be set to something. So
set it to AVX, as the instructions require the VEX prefix anyway (ICC
has no dedicated option for just F16C).

f1a23a5467 Basic Vulkan enablers
For Android, Windows and xcb. Verified on Win10 with NVIDIA, Win10
with AMD, Android with Tegra K1, Android aarch64 with Tegra X1, and
Linux aarch64 with Tegra X1 (Jetson TX1, L4T).

Introduce QPA-based Vulkan library loader, core function resolver, and
instance creation support. In addition to creating a new VkInstance,
adopting an existing one from an external engine is supported as well.

The WSI specifics are hidden in the platform plugins. Vulkan-capable
windows use the new surface type VulkanSurface and are associated with
a QVulkanInstance.

On Windows VULKAN_SDK is picked up automatically so finding vulkan.h
needs no additional manual steps once the LunarG SDK is installed.

[ChangeLog][QtGui] Added support for rendering to QWindow via the Vulkan
graphics API.

0f1b6acab7 x86: Add detection of the AES and SHA New Instructions
The AES instructions were first introduced with the Westmere shrink
(22nm) of the Nehalem architecture. The SHA instructions are still
pending on Intel architecture, but is available on AMD family 17h (gcc
argument -march=znver1).

Both features operate on SSE registers, so that's why the MSVC command-
line argument is the SSE2 one and the configure-time tests depend on
features.sse2.

The qmake feature names end in "ni" because "aes" and "sha" are too
simple and could clash with other uses. The QT_COMPILER_SUPPORTS_ macro
doesn't have the "NI" suffix because it has to match the GCC/Clang
predefined macro.

04403d5b12 Merge all "win32-msvc*" mkspecs into one
Since we can tell the MSVC version from the compiler now, each of the
qmake.conf files is now the same, so let's just have "win32-msvc" and be
future-proof. Likewise for win32-clang-msvc.

qplatformdefs.h was already common.

Since we can't obtain the MSVC version from the unified mkspec name any
more, I dropped the warning level during the qmake bootstrap to reduce
the number of warnings that need to be disabled from compiler version to
version.

There is no point in keeping the old mkspecs, but configure will re-map
the -platform argument to the unified spec as necessary, to keep
existing configure command lines working.

[ChangeLog][Visual Studio] Qt now has a common mkspec for all Visual
Studio versions, called "win32-msvc". The old names which contained the
version number are now gone (but qmake scopes based on the old names
continue to work). The version of the compiler can be obtained from the
MSC_VER and MSVC_VER variables (for example, for Visual Studio 2015,
those contain the values 1900 and 14.0, respectively). Those variables
are also available with the Intel compiler (win32-icc) and with Clang
(win32-clang-msvc).

the following in template functions:

    auto x = 1, y = 2;

3373: nonstandard use of "auto" to both deduce the type from an
initializer and to announce a trailing return type

Other reports on the Internet indicate that no one understands what
triggers this warning and have just worked around it. Additionally, the
same warning exists on other compilers with the same text, so it's
likely come from the EDG front-end. This has been reported to Intel.

780105f906 Merge ANGLE's libEGL and libGLESv2 into QtANGLE
This is needed in order to be able to specify a custom location of
the ANGLE libs, and enables us to perform a LoadLibrary of ANGLE libs
by just having the absolute path to QtANGLE.dll as the argument to
LoadLibrary().

Previously, we had two ANGLE libraries: libEGL and libGLESv2. libEGL hard
linked against libGLESv2.  If we wanted to load libEGL from a custom
location, we couldn't load libEGL by calling LoadLibrary with the absolute
path to libEGL, because libEGL had problems finding libGLESv2.  One
solution to that could have been to call SetDllDirectory() with the path
to the ANGLE libs before calling LoadLibrary("libEGL.dll"). Since the DLL
directory would point to both ANGLE libs, this would ensure that the libGLESv2
was also found.  Unfortunately, this approach is not thread safe
(SetDllDirectory will affect all subsequent LoadLibrary(Ex) from the same
process). Therefore, we chose to merge the two libraries into one to
circumvent the whole problem.

At the same time, this patch also enables loading of two different ANGLE
libraries into the same process at once without renaming them: This was
not possible before because libEGL hard linked to libGLESv2.dll.  When
libGLESv2.dll was already loaded, the second instance of libEGL would
simply link against the already loaded version of libGLESv2.dll.

This behavior is documented in the LoadLibraryEx documentation on MSDN:
"If the string specifies a module name without a path and more than one
loaded module has the same base name and extension, the function returns a
handle to the module that was loaded first."

4684c1afe5 Add detection of C++14 and C++1z compiler features
[ChangeLog][General Improvements] Qt's buildsystem now detects whether
the compiler supports C++14 and experimental support for C++1z. If the
compiler supports it, then Qt is automatically compiled using that
support.
\
This does not apply to user applications built using qmake: those are
still built with C++11 support only. To enable support for C++14 in your
application, add to your .pro file: CONFIG += c++14 (similarly for
C++1z).

95d385466d centralize setup of shell-related variables in spec_post.prf
it makes no sense to let every spec do that separately, as it's fixed
by the generator+shell.

putting it into a file which is loaded regardless of the spec also
allows us to remove the hardcoded fallbacks from qmake.

if somebody overrode the values in their spec for some weird reasons,
they'll need to override spec_post.prf.

shell-{unix,win32}.conf are now dummies and print warnings.

1bd27f24fb Add link-time optimization support for Clang, GCC and ICC
GCC currently requires fat object files for static libraries, since the
linker would otherwise not load the .o file from the archive at all and
the linking would fail with a lot of undefined references. 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.

032f0f543e Fix building of the C++11 config.test on Windows with ICL
The Intel compiler does support C++11 options on the command-line.
configure.exe will correctly try to run it, but the test would fail for
incorrect reasons.

First, we need to pass the option -Qstd=c++11 to enable it.

Second, on Windows, the GCC experimental define isn't defined, nor is
__cplusplus updated yet. So we have to rely on the Intel-specific macro.

Third, we need CONFIG += console so that the application succeeds in
linking against a main() function, as opposed to a WinMain one.

97c187da3c Dynamic GL switch on Windows
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.

5fcf441392 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

to the right and those belonging to 'proper code (TM)' have not been

The work was mostly done using the following python script (might
come in handy again...):

p = re.compile(r'(\w+)[ \t]*([\-\+]?)(=$|= )[ \t]*(.*$)')

                    n_spaces -= 1 # left-shift '+=' by one if the '+' is aligned to a multiple of 4

                nl = m.group(1) + ' '*n_spaces + ''.join(m.group(2,3,4)) + '\n'

Note A): the only non 3rdparty c++-files that still
have trailing whitespace after this change are:
* src/corelib/codecs/cp949codetbl_p.h
* src/corelib/codecs/qjpunicode.cpp
* src/corelib/codecs/qbig5codec.cpp
* src/corelib/xml/qxmlstream_p.h

* src/tools/uic/ui4.cpp
* tests/auto/other/qtokenautomaton/tokenizers/*
* tests/benchmarks/corelib/tools/qstring/data.cpp
* util/lexgen/tokenizer.cpp

Note B): in about 30 files some overlapping 'leading tab' and
'TAB character in non-leading whitespace' issues have been fixed
to make the sanity bot happy. Plus some general ws-fixes here
and there as asked for during review.
