For the raw pointer constructor, check that the argument is not on the
stack. Passing a stack pointer as an sp<> parameter is dangerous,
since we will attempt to deallocate the object once the sp<> is no
longer needed. We approximate ste stack ccheck by testing whether it
is on the same page as the frame pointer.
Do the same for raw pointer assignment.

Imagine an AIDL file:
package android.foo;
interface IFoo {}
The AIDL C++ backend will generate classes like "::android::foo::IFoo".
In order to avoid ODR conflict, the NDK (Stable C) backend linking
against libbinder_ndk puts everything under the "::aidl" namespace. So,
we have "::aidl::android::foo::IFoo". When using ScopedTrace in a class

This is a backward compatible implementation of compile time
constructed String16 support.
As much as we'd like a regular constexpr constructor for String16, we
want to make sure the regular non-static String16 does not regress.
We also need to make sure prebuilts built with previous version of
String16 still works with new libutils. This means we cannot change
the size of String16 objects and we cannot make anything virtual.
To add a flag to indicate whether a String16 is static without
increasing the size of non-static String16 objects, we repurpose a
reserved field in SharedBuffer as "for client use". With this, we can
tag every String16 and perform memory operation differently based on
how the underlying buffers are allocated.
By using StaticString16, we are able to eliminate the runtime
construction of a String16 and move it out of .bss section.

Android build system added support for building translated binaries
used on natively bridged targets (arm on x86 for example).
However in order to avoid building unnecessary binaries and libraries
for such architectures most modules do not support native bridge by default.
All needed modules have to explicitly indicate if they may be used as part
of translated binary build.
This change enabled native bridge support for libutils which is a

Fix wp and sp comparison bugs
Make clear() actually clear wp m_refs, so that nulls compare equal.
Make equality consistent with < and >, ensuring that a weak pointer
cannot be both equal to and greater than another.
Don't rely on the built-in < and > operators to correctly order
different objects. The standard does not guarantee that, and there is
a risk of compiler relying on that lack of guarantee.
Remove unnecessary comparison overloads, especially those
comparing a wp<> to an sp<>.
Change the remaining wp<> to sp<> comparisons to check for equivalence
of the mRefs pointer instead of the object address, thus eliminating
the dubious equal comparison result for a dead wp<> and an sp<> that
happen to point to the same object address.
Add comparison tests.
This reverts commit a2a2ad8057.
The original code, and my original CL, both failed to initialize m_refs
in various wp<> constructors. This now became more important, since
comparisons now rely more on m_refs. However I believe it was always

Move towards crashing if a normally configured RefBase object is
destroyed without ever incrementing the reference count. We've been
threatening to do this for a long time. The previously last known
violation had been fixed.
This also fixes stack trace printing from RefBase, which had previously
been broken, and which we found necessary to track down further
violations of this rule.
Unfortunately, we found several more violations with the aid of
that fix. After existing CLs are submitted, there are
still some failures, but they are no longer numerous. Thus this CL
doesn't actually crash in the event of a violation, but does log a
verbose stack trace if it encounters one.
Bugs have been filed against the remaining known RefBase client offenders.
We plan to enable crashing on usage violations once those are fixed.
The fix for the stack trace printing breakage unfortunately requires
the use of weak symbols in order to avoid a circular build dependency.
We expect to eventually replace this with execinfo.h functionality.
Some random reformatting, driven by consistency with current formatting
requirements.

adbd has been built as a static executable since the same binary was
copied to the recovery partition where shared library is not supported.
However, since we now support shared library in the recovery partition,
adbd is built as a dynamic executable.
In addition, the dependency from adbd to libdebuggerd_handler is removed
as debuggerd is handled by the dynamic linker.
A few more modules in /system/core are marked as recovery_available:
true as they are transitive dependencies of the dynamic linker.
This change also includes ld.config.recovery.txt which is the linker
config file for the recovery mode. It is installed to /etc/ld.config.txt
and contains linker namespace config for the dynamic binaries under
/sbin.

This is baked into too many prebuilts. Perhaps
eventually it can be removed, but this is very

As a VNDK-SP module, Android.bp must have 'vndk' tag as well as
'vendor_available: true'.
The 'vndk' tag for VNDK-SP formated as follows:
vndk: {
enabled: true,
support_system_process: true,
},
VNDK-SP modules will be installed both in system/lib(64) as normal
and in system/lib(64)/vndk-sp as a vendor variant.
