Listing a library in any of:
LOCAL_EXPORT_SHARED_LIBRARY_HEADERS
LOCAL_EXPORT_STATIC_LIBRARY_HEADERS
will cause the headers exported by that library to be exported from
the current library target as well.
This means that when library A's public headers include headers from
library B, library C which consumes A no longer has to explicitly list
A and B in its LOCAL_SHARED_LIBRARIES for the purpose of picking up B's
headers.
Bug: 27804373
Test: Introduced dependency on libbase to libbinder at the header level.
Libraries that consume libbinder do not need to explicitly depend

Used to select between releases of the NDK (r10, r11, etc).
Some of the libraries we use in Android come as prebuilts from
google3, which are most likely built against an older NDK than what
we have in the platform. Since things may not be ABI compatible
release to release, we need to keep legacy versions accessible for
those to keep building.

Clang and MinGW are not expected to work together currently, and you get
strange errors when this is attempted. Instead, error out with a clear
error message.
Before the windows build rewrite, we'd just explicitly set my_clang to
false without checking what the module asked for. Now, error out if the
module explicitly asked for clang, since by default they'd have it
already if it wasn't for windows. That way when Clang+Windows does
become possible, it can gradually be tested by setting LOCAL_CLANG to
true.

Why? For one, libgcc's unwinder makes use of `dl_iterate_phdr`. Also,
libgabi++ (the home grown C++ RT we use for stlport) uses
`dlopen` for liblog when reporting fatal errors. The LLVM unwinder
which is used by libc++ also uses libdl.
Requiring a dependency on libdl seems less objectionable than
requiring one on liblog. We could always change libgabi++ to use
syslog instead, but that will only reach logcat for newer devices
(possibly L+, definitely M+).
Requiring libdl seems like the best option here, especially given
that libgcc needs it anyway.

When BUILDING_WITH_NINJA==true, only update export_includes if it

Pass -fsanitize=address instead of manually specifying asan libraries
and other linker flags.
Note that we enable LOCAL_ALLOW_UNDEFINED_SYMBOLS by default for host
builds because ASAN only links symbols in the final executable, so
there will _always_ be undefined symbols in intermediate libraries.

The previous position of libgcc.a/libatomic.a on the link line causes
the linker to prefer satisfying dependencies from these libraries from
other libraries that might include them, rather than from libgcc.a (or
libatomic.a) itself. This imposes an ABI requirement that those
intermediate shared libraries _always_ export those symbols, which is
undesirable.

The NDK protobuf library depends on the final target linking stlport
(since it is a static library). Since the platform stlport is going
away, we need to use a separate version of the protobuf library that
is compiled for the platform against libc++.
Note that this should be the case for _all_ libraries built with the
NDK. If a library needs to be used by both an NDK built final target
and a platform built final target, there should be both an NDK and
platform version of the library.

Only sort the list of shared libraries used for naming dependencies,
not the order they are actually linked in. The order in which shared
libraries appear to the linker affects which symbols get used if there
is a multiply defined symbol.
Also link system shared libraries _after_ user provided libraries,
since a user will want their functions to override the system's if
they exist.

To enable building with coverage, the environment variable
NATIVE_COVERAGE must be set to true.
Set `LOCAL_NATIVE_COVERAGE := true` to generate coverage information for
a given component.
This is currently not supported for clang (b/17574078, b/17583330).
If static library A is included in a binary B (dynamic or static
executable, or shared library), and A is built with coverage
information, B is required to link with libgcov.a. Since the make does
not offer a good way to track this dependency, link libgcov.a even if
LOCAL_NATIVE_COVERAGE is not set (but still guarded by NATIVE_COVERAGE).
This ensures that all of the libgcov dependencies will always be
resolved, and causes no change in the resulting binary if coverage is
not used.

Preparing for migration from stlport to libc++. STL selection is done
with LOCAL_CXX_STL (valid values are default, none, libc++,
libc++_static, stlport, stlport_static, bionic).
The selection of the STL is as follows:
if LOCAL_CXX_STL == 'default'
ifdef LOCAL_SDK_VERSION
Use whatever STL the other NDK options have selected.
else
Use bionic's libstdc++ for target, GNU libstdc++ for host. This
is compatible with the existing build options.
endif
else
if LOCAL_CXX_STL == 'stlport'

else if LOCAL_CXX_STL == 'libc++'

We've been using -fPIC and -fPIE together in the global cflags all this
time. These options are incompatible. The only reason we haven't been
hit by this before is because of the forced -Bsymbolic in GCC. To fix
this, pass -fpic when compiling objects for shared libraries and -fpie
when compiling objects for executables. For static libraries, also use
-fpic. We have to do this because static libraries might be included in
either a shared library or an executable. Code compiled with -fpie
cannot be included in a shared library, but code compiled with -fpic
may be included in an executable.
We've also been using -fpic and -fPIC together. These are different
options, and only the latter will take effect.

The final thing this fixes is that we had -f(PIC|PIE) flags being passed
to link commands. These are compile time flags, and don't do anything at
link time.

Previously we only expanded product_MODULES with LOCAL_REQUIRED_MODULES,
but not modules introduced by LOCAL_SHARED_LIBRARIES; Later we did a further
shared libary expansion in vendor_module_check.mk.
It couldn't track C in the following case:
A : B, by LOCAL_SHARED_LIBRARIES; B : C, by LOCAL_REQUIRED_MODULES.
With this change, we transformed the LOCAL_SHARED_LIBRARIES dependencies
into LOCAL_REQUIRED_MODULES dependencies before doing the required
module expansion and the loophole is closed.
All module names are now expanded to product_MODULES now and it makes
vendor_module_check.mk simpler.

Previously the RS cpp files are generated by the timestamp rule. Though
we have the generated RS cpp files depend on the timestamp file, we
don't have a build recipe. In such case gmake does some "optimization"
that it skip recompiling the generated cpp files, because it assumes the
generated cpp files are already up to date even if the rs files have
been updated.

This fixed issue that gnumake skip updating the cpp file that includes
the generated header file when the .proto file gets updated.
For example:
Say a.cc includes b.pb.h, since b.pb.h is just byproduct of the rule
that generates b.pb.cc, and though we have dependency "b.pb.h :
b.pb.cc", but we don't have build recipe for that rule.
Gmake stupidly thinks that b.pb.h must not be updated in that case so
it skips all targets that depends on b.pb.h!
With the dumy build recipe, gmake now doesn't skip the depedent targets.

This change basically ported our target multilib to the host side.
It supports 2 host build modes: x86 and x86_64 multilib build.
For now you need to set "BUILD_HOST_64bit=true" to switch to x86_64
multilib build. Later we'll default to x86_64 build and have a flag
to force 32-bit only build, which may be needed by SDK build.
In host module definition, like in target ones, you can use the
following
LOCAL variables to set up multilib configuration:
LOCAL_MULTILIB: can be "both", "first", "32" or "64".
It also supports the same set of arch or 32-vs-64 specific LOCAL
variables.
By default, it builds only for the first arch.
To keep path compatibility, in x86_64 build files are still output to
out/host/linux-x86; Both 32-bit and 64-bit executables are in
out/host/linux-86/bin;
In x86_64 build 32-bit shared libraries are installed to
out/host/linux-x86/lib32
and 64-bit shared libraries are installed to out/host/linux-x86/lib;
32-bit object files are output to out/host/linux-x86/obj32 and 64-bit
object files
are output to out/host/linux-x86/obj.
