7f283f4bd0 Refine logic choosing vendor snapshot modules
This refines the vendor snapshot codes in order to fix logic errors.

- Capture toolchain_library and cc_library_headers correctly.
- Redirect unwind static library correctly.
- Filter out sanitize / coverage / lto by looking at HideFromMake.
- Add binary() function for clear and shorter codes.
- Include test modules.
- Add more tests to prevent further snapshot breakages.

c988c8e202 Move prebuilts mutators after defaults have been applied
A follow up change will add a mechanism for a module to register a hook
that is called after any defaults have been applied. That is intended
for use by modules like java_sdk_library that create child modules that
are dependent upon properties that could be supplied by defaults.

Creating those child modules after prebuilts mutators are run will
cause problems if those child modules clash with prebuilts modules.
Moving the prebuilts mutators after the defaults mutators will fix
that.

Tests are currently being run with the mutators in different orders so
this change also cleans that up so they are consistent with the actual
code that is being run.

a0cd8f9acb Add gcov coverage support to Rust modules.
This adds gcov coverage support for Rust device library and binary
modules (including test modules). Support is provided to pass Rust
static library gcno files to CC modules and visa versa.

Additional changes:
 * Begin mutator added for Rust modules.
 * SuffixInList added to android package.
 * CoverageEnabled added to Coverage interface.
 * CoverageFiles added to LinkableLibrary interface.
 * Fix in coverage mutator for non-CC modules which marked the wrong
   variant as the coverage variant.
 * Added coverage libraries to the cc.GatherRequiredDepsForTest.

7556839772 Enforce apex.min_sdk_version for bundled builds
Previously, when Q-targeting apexes are bundled-built, they are built
against the latest stubs.

It was because unwinder is linked dynamically in R and APIs are provided
by libc while Q apexes should run on Q where libc doesn't provide those
APIs. To make Q apexes run on Q device, libc++ should be linked with
static unwinder. But, because libc++ with static unwinder may cause problem
on HWASAN build, Q apexes were built against the latest stubs for bundled
build.

However, Q apexes should be built against Q stubs.

Now, only for HWASAN builds, Q apexes are built against the latest stubs
(and native modules are not linked with static unwinder).

82e192c3ae Add sdk mutator for native modules
Compiling native modules against the NDK disables platform features
like ASAN.  For anything shipped on the system image there is no
reason to compile against the NDK.  Add a new mutator to Soong that
creates a platform and an SDK variant for modules that set
sdk_version, and ignore sdk_version for the platform variant.  The
SDK variant will be used for embedding in APKs that may be installed
on older platforms.  Apexes use their own variants that enforce
backwards compatibility.

a04c107bfa Add support for multiple os types
Updates the member snapshot creation code to support multiple os types.
It basically sorts the variants by os type, then applies the code to
optimize the arch properties and then it optimizes the properties that
are common across architectures and extracts any properties that are
common across os types.

The java and cc member types needed to be modified to make the location
of the generated files within the snapshot os type dependent when there
is more than one os type. That was done by adding an OsPrefix() method
to the SdkMemberPropertiesBase which returns the os prefix to use when
there is > 1 os type and otherwise returns an empty string.

Added three tests, one for cc shared libraries, one for cc binary and
one for java header libraries.

8471cdaced Implement vendor snapshot
Vendor snapshot can be captured with "m dist vendor-snapshot". With
vendor snapshot and vndk snapshot, older version of /vendor and newer
version of /system will be able to be built together by setting
BOARD_VNDK_VERSION to past vendor's version.

Only vendor modules under AOSP are to be captured. In detail, modules
under following directories are ignored:
- device/
- vendor/
- hardware/, except for interfaces/, libhardware/, libhardware_legacy/,
  and ril/

Test modules (cc_test, etc.) and sanitized modules are also ignored.

e5ba28648f build: Link the unwinder dynamically into platform and vendor binaries.
Instead of linking the unwinder statically into every binary, link it
dynamically, by exporting the symbols from libc.so. This has a number
of advantages:

- Reduces image size (system.img size decreases by 1.7MB on walleye-userdebug,
  and 1.2MB on crosshatch-userdebug).
- Allows us to easily change/upgrade the unwinder throughout the system,
  including vendor prebuilts.
- Allows code outside of libc++ to define custom personality routines.
  Previously, personality routines would call the unwinder routines in the
  local binary, which would cause problems with unwinders with global state
  (such as the libgcc unwinder) if the copy of the unwinder used for unwinding
  (normally libc++'s copy) were different from the copy linked against the
  personality routine.

075c417837 Improve cc tests by adding fuzzer mutators
This fixes an issue that arises when deduping cc build component
registration code.

The fuzzer and fuzzer_deps post deps mutators were not previously
added when running cc tests. That meant the tests were not actually
testing the same behavior as at runtime.

Adding the mutators breaks the TestFuzzTarget test as the mutator
changes the variant of the fuzz_smoke_test that is created and so the
test fails to find it.

This fixes the test by correct the variant name.

This fixes an issue that arises when deduping cc build component
registration code.

The sanitize_runtime_deps and sanitize_runtime post deps mutators were
not previously added when running cc tests. That meant the tests were
not actually testing the same behavior as at runtime.

Adding the mutators breaks the TestFuzzTarget test as the mutator adds
libclang_rt.ubsan_standalone-aarch64-android as a dependency of libc++
and the former is not available.

This fixes the test by adding the missing dependency as a cc prebuilt
shared library.

77980a8bb9 Dedup registration for cc default test config
The cc.GatherRequiredDepsForTest() method returns some default module
definitions that are required when using cc module types like
cc_library. Previously, the registration of the module types and

in the test config initialization.

This change removes that duplicated code and replaces it with calls
to cc.RegisterRequiredBuildComponentsForTest(ctx) which registers all
the required build components.

da9a463794 Add the cc_fuzz target.
Adds the cc_fuzz target via a cc_fuzz module. Also implements the
libclang runtime interface for the x86 toolchain to allow host-built
fuzzers.

Bug: 137398545

Test: Build a fuzzer (with all topic patches), notice that you now
have a host-built fuzzer :)

380029182c soong: fix wrong link type for VNDKs
Do not rely on 'module.Name()' to decide VNDK link type.
Some prebuilt modules such as libclang_rt_prebuilt_library_shared and
vndk_prebuilt may have different naming schemes.(prefix/suffix)
And llndk_library module has '.llndk' suffix.

Instead, use VNDK-related properties (e.g. vndk.enabled,
vendor_available, etc.).

815daf95b2 Add bpf_test.go to build and fix tests
bpf_test.go was not listed in testSrcs, which meant it was not run
during the build, but ran and failed with go test android/soong/...

Don't redeclare the cc module types and mutators, use exported
functions from cc/testing.go instead, which contain a new
dependency needed by cc modules.

This reapplies I4542640e8ff08e71565ed50617dbe67d86b29b69 after
fixes for mac tests.

Test: m
Test: go test android/soong/...

acee27cd72 Strip libgcc to only keep fallback symbols
We use libgcc as fallback for symbols not present in libclang_rt
builtins, however we didn't know what exact symbols were being used,
some may not be intended to fallback.

Create libgcc_stripped, which only contains unwind symbols from libgcc.

1f959769f3 Remove libbase dependency of sysprop_library
libbase dependency is not really needed, but it has been causing build
failure while linking with static variant of sysprop_library. This cuts
the dependency and only depend on libbase_headers and liblog.

Bug: 129301987
Test: 1) flash and boot walleye
Test: 2) try to build various properties with sysprop_library.
Test: 3) sysprop_test

c0907f191a Create sysprop_library soong module
A newly introduced sysprop_library soong module will generate a
java_sdk_library and a cc_library from .sysprop description files.
Both Java modules and C++ modules can link against sysprop_library
module, thus giving consistency for using generated sysprop API.

As Java controls accessibility of Internal / System properties with
@hide and @SystemApi, 2 different header files will be created. And
build system will selectively expose depending on the property owner
and the place where the client libraries go into.

Test: 1) Create sysprop_library module.
Test: 2) Create empty txt files under prebuilts/sdk.
Test: 3) Create api directory, make update-api, and see changes.
Test: 4) Try to link against sysprop_library with various clients.
Test: 5) Soc_specific, Device_specific, Product_specific, recovery flags
work as intended.
