This was originally enabled in the mkspecs for 64-bit QNX 7.0.0
but that broke when the qtConfig change was made. It looks like
qtConfig shouldn't be used in the platform mkspecs. I suspect
the stack-protector changes were left out of the 32-bit mkspecs
so that 6.6.0 builds wouldn't be affected.
Ignore the stack-protector/stack-protector-all possibility since
it isn't possible to access it without a command line option.
Specifying both options doesn't even make sense since
stack-protector-all encompasses stack-protector.
For now, leave out command line control of this feature.

qmake config defines tvos (but not ios).
tvOS is 64bits only (QT_ARCH is arm64) and requires bitcode to be

other configurations, only using bitcode markers to keep file size

[ChangeLog][General Improvements] Qt's buildsystem now detects whether

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

The linker complains that some symbols were compiled with different visibility
settings when linking host_build tools such as the import scanner. As it turns
out, we do CONFIG += hide_symbols for static libraries (such as bootstrap or
qmldevtools) but naturally not for the final program source code. It appears
symbol visibility is not of importance for static libraries in host builds (as
opposed to static libraries later linked into shared libraries), therefore this
patch removes that.

This would mean we don't pass -Werror when under CONFIG += warn_off.
However, that's not the main goal. The main goal of this change is to
have -Werror appear *after* -Wall -Wextra.
With some compilers, like Clang, this is necessary to have the
-Wno-error=foo options work properly. For example, if the -Wfoo
warning gets enabled by -Wall, Clang will treat it as an error if the
arguments appear in the following order:
-Werror -Wno-error=foo -Wall
But not if they appear in this order:
-Wall -Werror -Wno-error=foo

We used to compute the default exclusive build directory, eg 'debug', at
configure time, and then set OBJECTS_DIR, MOC_DIR, etc to include this
hard-coded default exclusive build directory. We then had to run a post-
process step where we replaced the 'debug' part with the current actual
exclusive build pass, eg 'release', resulting in long-standing bugs such
as QTBUG-491 where we end up replacing parts of the build output dirs
that were not part of the original exclusive build directory.
We now set the OBJECTS_DIR, MOC_DIR, etc defaults in configure like
before, but they do not include any exclusive-build information. The
exclusive build directory is handled as a separate step in default_post
where we adjust all entries in QMAKE_DIR_REPLACE to be exclusive
directories.
For backwards compatibility the new exclusive build behavior is only
enabled for variables named by QMAKE_DIR_REPLACE_SANE, which for Qt
itself applies globally to everything but DESTDIR, and for libs and
tools also applies to DESTDIR. The reason for leaving out DESTDIR in
the general case is because many tests and examples assume the old
behavior for DESTDIR. A side effect of including all the other
variables for Qt libs and tools is that the PCH output dir will be
uniformly set, which has been an issue on Windows in the past.
The addExclusiveBuilds function now takes two or more arguments,
each argument being the key for an exclusive build, which can be
customized eg. using $$key.{name,target,dir_affix}. Passing more
than two arguments results in three/four/etc-way exclusive builds,
eg debug/release/profile. Exclusive builds can also be combined, eg
static/shared + debug/release by making two calls to the function.
We also handle individual targets of combined exclusive builds,
eg static/shared + debug/release, meaning it is possible to run
'make debug' to build both static-debug and shared-debug.
