APEX variants that share the same SDK version and updatability
almost always use identical command line arguments to build but
with different intermediates directories. This causes unnecessary
build time and disk space for duplicated work.
Deduplicate APEX variants that would build identically. Create
aliases from the per-APEX variations to the new shared variations
so that the APEX modules can continue to depend on them via the
APEX name as the variation.
This has one significant change in behavior. Before this change,
if an APEX had two libraries in its direct dependencies and one
of those libraries depended on the other, and the second library
had stubs, then the first library would depend on the implementation
of the second library and not the stubs. After this change, if
the first library is also present in a second APEX but the second
library is not, then the common variant shared between the two
APEXes would use the stubs, not the implementation.
In a correctly configured set of build rules this change will
be irrelevant, because if the compilation worked for the second
APEX using stubs then it will work for the common variant using
stubs. However, if an incorrect change to the build rules is
made this could lead to confusing errors, as a previously-working
common variant could suddenly stop building when a module is added
to a new APEX without its dependencies that require implementation
APIs to compile.
This change reduces the number of modules in an AOSP arm64-userdebug
build by 3% (52242 to 50586), reduces the number of variants of the
libcutils module from 74 to 53, and reduces the number of variants
of the massive libart[d] modules from 44 to 32.

We don't need the prebuilt versions. The NDK CRT objects are (now)
built from the platform sources and the only difference is that the
NDK CRT objects also include an ELF note that identifies the NDK
version, which isn't helpful for anything built by the platform.
Add a `crt` property to cc_object that allows CRT objects to identify
themselves. CRT objects, unlike other modules, will have a variant
built per-API level they support, rather than just an SDK variant and
a platform variant. This is needed because new CRT objects will rely
on APIs not available in old libcs and old CRT objects will not
support all the features of a modern one.

Alias the shared variation if it exists, otherwise the static variation.
This allows modules that are not aware of shared library variations

just the normal image, os and arch variations.

Use local variations and an alias for the "" variation for
versionMutator. Local variations are used here because the variation
of one module doesn't affect the variation it should depend on - a
module with variation version:29 will manually link against dependencies
with the correct version variation, and don't need it to be automatically
resolved. The alias allows other modules to depend on a module
mutated by the version mutator without specifying the version: ""
variation. This allows removing the variation on genrule modules.
The motiviation here is to make sure versionMutator calls AliasVariation,
which will allow the previous linkageMutator to also use AliasVariation.

CFI modules can't link against non-CFI static libraries, and vice versa.
So without capturing both CFI and non-CFI static libraries, vendor
modules won't be able to use CFI, which will be a critical security
hole.
This captures both CFI and non-CFI variants of all static libraries for
vendor snapshot, except for those whose cfi are explicitly disabled.
For example, suppose that "libfoo" is defined as follows.
cc_library_static {
name: "libfoo",
vendor_available: true,
}
As it doesn't have cfi disabled, two libraries "libfoo.a" and
"libfoo.cfi.a" will be captured. When installed, vendor snapshot module
for "libfoo" will look like:
vendor_snapshot_static {
name: "libfoo",
src: "libfoo.a",
cfi: {
src: "libfoo.cfi.a",
},
}
The build system will recognize the "cfi" property, and will create both
CFI and non-CFI variant, allowing any modules to link against "libfoo"
safely, no matter whether CFI is enabled or not.
Two clarification:
1) The reason why we don't create separate modules is that DepsMutator
runs before sanitize mutators. CFI and non-CFI variant of a library
should exist in a single module.
2) We can't capture CFI variant if the source module explicitly disables
cfi variant by specifying the following.
sanitize: {
cfi: false,
}
In this case, only non-CFI variant will be created for the vendor
snapshot module.

Optimize build by removing redundant edges from the dependency graph.
After this change abidump files (.sdump, .lsdump, .abidiff) are built
only if (1) building phony target `findlsdumps` or (2) reference dump
is present under prebuilts/, which is the case for REL branches.
This improves the build time by 1.5 minutes on my machine.
Also remove HEADER_ABI_DIFFS because it has no user anymore.

Dependencies of makefile modules are being redirected according to
SOONG_CFI_STATIC_LIBRARIES and SOONG_HWASAN_STATIC_LIBRARIES. But the
variables are shared among all variants (e.g. core, vendor, product,
arch), which can cause build error.
This splits the Makefile variables into several lists, one list per each
arch and each image variant, to correctly make the redirection.

Necessary to avoid problems with implicitly enabled host OS'es, e.g.
linux_glibc getting enabled when we only supply a linux_bionic linker
in runtime-module-host-exports. That will then cause a non-functional
prebuilt to take precedence over source if the prebuilt is preferred.
We don't do this for device since we so far only support a single
device OS (android).
This introduces the notion that SDK member types can be host OS
dependent or not. That way java members with host prebuilts don't get
restricted to a specific host OS.

Previously, the prebuilt mutators were added by the
cc.RegisterRequiredBuildComponentsForTest() function as a convenience
but unfortunately it lead to some of the mutators being in a different
order in the tests than in the normal build.
This change:
* Extracts the RegisterPrebuiltMutators() call from
cc.RegisterRequiredBuildComponentsForTest()
* Makes sure that the prebuilt mutators are registered before the
visibility gatherer and enforcer mutators.

dependencyTag uses a set of predefined tags to identify different types
of dependencies. There are already multiple bits of metadata stored
in the dependency tag (Library, Shared, ReexportFlags), and supporting
them all requires a combinatorial explosion of predefined tags and
causes issues when using equality comparisons if a new bit of metadata
is added.
Add a new libraryDependencyTag type that will contain the metadata
bits, and replace the quality comparisons with checks on the metadata
bits.
There are 5 TODOs where modifying the checks identified problems with
the existing checks. These were left in place to produce identical
build output and will be fixed separately.
