Bug 1256642 introduced magic at the emitter level to determine whether a
binary contains C++ sources and should be linked with the C compiler or
the C++ compiler.
Unfortunately, the Binary() moz.build template always adds C++ OS
libraries on Android (through STLPORT_LIBS), and C++ libraries on Linux
(stdc++compat).
The latter only ends up forcing every Binary() to be linked with the C++
linker, which is unfortunate, but doesn't cause much problems. The
former, however, involving OS libraries, the magic from bug 1256642
doesn't kick in, so we end up trying to link C++ OS libraries with the C
linker. Which ends up failing, because the libraries in STLPORT_LIBS
require -lm, which, while it's added by the C++ compiler when linking,
is not when the linkage is driven by the C compiler.
Because the fallible library, linked to all GeckoBinary()s is a C++
library, we still ended up linking with the C++ compiler on Android, so
this wasn't actually causing any problem... until I tried to remove that
fallible library in bug 1423803.
Anyways, the core problem is that moz.build evaluation is happening too
early to know whether any C++ sources are being linked together, so
there is no way the Binary() template can do the right thing. So this
change moves the logic to the emitter.
This also changes the type of STLPORT_LIBS to a list.

Stylo's bindgen is configured partially through a .toml.in file that
substitutes the value of a configure variable (BINDGEN_CFLAGS) into a
TOML list. We can debate whether this is a good thing to do some other
time; the reality is that the current moz.configure code that provides
the set_config for BINDGEN_CFLAGS needs to perform all the quoting
itself.
We want, however, to define the substituted variable in old-configure.in
land (some of the values that will go into BINDGEN_CFLAGS are only
defined in old-configure.in, and are not trivially ported to
moz.configure), which means that we need to have quoting logic in
m4/Python when we generate config.status. This patch adds an
appropriate macro for doing so.
The various AC_SUBST macros generate AC_SUBST_*FOO macros for holding the
values to substitute. The macros also cross-check the AC_SUBST_* macros
generated by other variants to make sure that you don't try to do
something like AC_SUBST(FOO) and AC_SUBST_SET(FOO). However, the check
in AC_SUBST_SET for AC_SUBST_LIST duplicate is missing an underscore:
the AC_SUBST_LIST macro generates another macro starting with
AC_SUBST_LIST_, but the AC_SUBST_SET macro checks for the prefix
AC_SUBST_LIST, which is missing the trailing underscore.
As we're going to be adding yet another AC_SUBST_* macro variant, and
therefore adding more checks to all existing macros, let's clean this up
before we start.
NDK r15+ clang changed the code generation strategy for the __atomic_*
intrinics such that using them with 64-bit types now requires linking
with libatomic. Our current configure tests for libatomic doesn't catch
this, because the std::atomic implementation is such that it doesn't
require an external library, even for 64-bit types, whereas the
__atomic_* intrinsics do. The safest thing to do is to force this
configure check to always return true when we are compiling for
x86/Android with clang.
The NDK clang needs to be informed about the existence of a GCC
toolchain, so important programs like the linker can be located. With
this change, we're starting to use command-line options that are
incompatible with GCC, so we also add a check to inform the user about
the non-support for this configuration.
While we're here, provide a reference to unique_list as defined in
moz.configure when executing config.data to avoid its redefinition
in m4.

Although there is emulator command in android_sdk_root/tools even if Android
Tools 26, it doesn't work well because emulator64-arm is missing in same

Valild emulator command moves from android_sdk_root/tools to

pass stlport flags to clang, I would like to move STLPORT_CPPFLAGS to

This patch does two things:
- add a Gradle-only ANDROID_COMPILE_SDK_VERSION substitution;
- uses it while uniformizing all of the Gradle Android SDK version
configurations.
The approach is fairly standard (and we were using it already); see,
for example
https://medium.com/@ali.muzaffar/gradle-configure-variables-for-all-android-project-modules-in-one-place-5a6e56cd384e
This will make bumping the Gradle configuration versions forward
easier.

This is just a small piece in the larger project of minimizing the set
of global AC_DEFINEs. None of these are relevant to C/C++ code;
they're mobile/android specific, so we should get them out of
mozilla-config.h.
In addition, this replaces hard-coded values with values from the
build system throughout mobile/android.

The -fsanitize=integer analysis from UBSan can be helpful to detect signed and unsigned integer overflows in the codebase. Unfortunately, those occur very frequently, making it impossible to test anything with it without the use of a huge blacklist. This patch includes a blacklist that is broad enough to silence everything that would drain performance too much. But even with this blacklist, neither tests nor fuzzing is "clean". We can however in the future combine this with static analysis to limit ourselves to interesting places to look at, or improve the dynamic analysis to omit typical benign overflows.
It also adds another attribute that can be used on functions. It is not used right now because it was initially easier to add things to the compile-time blacklist to get started.
Finally, it includes a runtime suppression list and patches various parts in the test harnesses to support that. It is currently empty and it should not be used on frequent overflows because it is expensive. However, it has the advantage that it can be used to differentiate between signed and unsigned overflows while the compile-time blacklist cannot do that. So it can be used to e.g. silence unsigned integer overflows on a file or function while still reporting signed issues. We can also use this suppression list for any other UBSan related suppressions, should we ever want to use other features from that sanitizer.

For parts of configuring Stylo, we need information about the library
extensions on all of our platforms, and this change is a reasonable way
to get at that information without duplicating it in two places. Plus
moving more things to moz.configure is more better.
This intentionally allows to set MOZ_INSTALL_TRACKING without
reference to the milestone being release or beta. That is, we
separate the default value (which depends on release or beta) from the
value specified, making life easier for developers.

It looks like Google decided to split these jars out a bit, so we need to piece
them all back together.
We could probably just query the sdk version instead, but I'm not 100% sure
know when this setup changed - moreover we don't know when (if?) the paths
are likely to change again. SDK 26.0 still has lint 25.3.1, so the SDK and
lint versions don't appear to be tied.
It seems that only the lint* jars are needed to compile 'build/annotationProcessor',
however we need all the remaining jars in the classpath when running that code
in 'widget/android/bindings'.

This ensures that we correctly link against /usr/lib/libc++.1.dylib.
With this flag left in LDFLAGS, the linker would find libc++.1.dylib in
clang/lib, which would cause us to link against @rpath/libc++.1.dylib.
