Ivan Lozano 63bb7680c9 rust: Add whole_static_libs, revert static_lib
Revert the static_lib behavior to the previous behavior (pass static
libs to the linker rather than via to rustc using `-lstatic=<lib>`). To
bundle static libraries into libraries, provide the whole_static_libs
property which retains the current static_libs behavior.

Passing all static libraries via -lstatic was resulting in odd bloat
where in some cases static symbols were duplicated in binaries and
libraries. This split makes it possible to be explicit about when static
libraries should be bundled.

Jiyong Park fdaa5f7164 Versioned CRT objects are built with correct __ANDROID_API__
Background: `min_sdk_version` of a crt object is the oldest SDK version
that the crt object supports. When it's set to for example 16, Soong
creates a number of versioned variants of the crt object starting from
16 to the latest version. The variant for version X is provided to NDK
clients having `min_sdk_version` set to X.

Problem: all versioned variants of a crt object were built with `-target
<arch>-linux-android16`. Therefore they all have been with `#define __ANDROID_API__
16`.  This is because the mutated variants still have the same
min_sdk_version property and the clang triple follows min_sdk_version,
not sdk_version. This is too conservative and against our intention to
provide the latest crt object that matches with the min_sdk_version of
the client.

In the other hand, the platform(non-sdk) variant of the crt object
doesn't have such a problem. min_sdk_version is completely ignored.
However, this is a bug and will be fixed by aosp/1640364. As a side
effect of the fixing, the platform variant will begin to built with a
very old __ANDROID_API__ which unnecessarily turns off the new platform
features like the TLS segment over-alignment.

This change fixes the problems:

* For the versioned variants of crt objects, we set both
`min_sdk_version` and `sdk_versio` to the version that the variant is
created for.

* For the platform variant of crt objects, `min_sdk_version` is force
reset to "current".

Justin Yun cbca373efa Use target dependent module to update the name suffix
The module names for vendor and product variants have the image
variant suffix to avoid conflict with the core modules. It requires
updating the module names in the dependency tree with the suffixes.

We had a hidden bug that used the original module properties to
update the names of its dependent modules.
Also, it must cover the product variants modules.

Colin Cross 127bb8b9f6 Don't rewrite LLNDK dependencies with .llndk suffix
Rewriting LLNDK dependencies with .llndk suffix requries referencing
a global data structure to determine if a given library is an LLNDK
library and therefore needs the .llndk suffix.  References to
global data structures from mutators must be removed to support
incremental Soong analysis.  Instead, move the LLNDK stubs rules
into the vendor variant of the implementing cc_library so that
the original name can be used.

As an incremental step, the llndk_library modules are left in
place, and the properties are copied into the cc_library via
the dependency specified by the llndk_stub property.  A followup
will move the LLNDK properties directly into the cc_library and
delete the llndk_library modules.

The global list of LLNDK libraries is kept for now as it is used
to generate the vndk.libraries.txt file.

Colin Cross 0de8a1e17b Start using Providers instead of direct module access
Export information about static libraries, shared libraries and
exported flags through Providers instead of accessing the module
directly.  Much more is left to be converted, but this significantly
simplifies the dependencies on libraries with stubs by making it easy
for a module to masquerade as another by simply exporting the
providers from the other module.  Instead of depending on all the
versions of a library and then picking which one to use later, it
can depend only on the implementation variant and then select the
right SharedLibraryInfo from the variant.

Colin Cross 6e511a9a9f Add libraryDependencyTag to track dependencies on static and shared libraries
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.

Jiyong Park 2286afd0ef Don't create version variants for SDK variants
When a lib has sdk_version set, an SDK variant and a platform variant
are created by the sdkMutator. Then by the versionMutator, if the
library had 'stubs.versions' property, one or more versioned variants
and one impl variant are created for each of the two (SDK and platform)
variants. As a concrete example,

cc_library {
    name: "foo",
    sdk_version: "current",
    stubs: { versions: ["1", "2"], },
}

would create 6 variants:

1) (sdk: "", version: "")
2) (sdk: "", version: "1")
3) (sdk: "", version: "2")
4) (sdk: "sdk", version: "")
5) (sdk: "sdk", version: "1")
6) (sdk: "sdk", version: "2")

This is somewhat uncessary because the need for the SDK mutator is to
have the platform variant (sdk:"") of a lib where sdk_version is unset,
which actually makes sens for the impl variant (version:""), but not
the versioned variants (version:"1" or version:"2").

This is not only unncessary, but also causes duplicate module
definitions in the Make side when doing an unbundled build. Specifically,
The #1 and #4 above both are emitted to Make and get the same name
"foo".

To fix the problem and not to create unnecessary variants, the versioned
variants are no longer created for the sdk variant. So, foo now has
the following variants only.

1) (sdk: "", version: "") // not emitted to Make (by versionMutator)
2) (sdk: "", version: "1") // not emitted to Make (by versionMutator)
3) (sdk: "", version: "2") // emitted to Make (by versionMutator)
4) (sdk: "sdk", version: "") // not emitted to Make (by versionMutator)

Jiyong Park 678c881a4f <apex_name>-deps-info correctly tracks dependencies
The APEX dependency is more correctly tracked. Previously, the
dependency was tracked while we gather modules that will be installed to
an APEX. This actually was incorrect because we skipped many dependency
types that we don't need to follow to gather the modules list, such as
the headers dependency.

Now, the dependency is tracked directly when a module is mutated for an
APEX. In other words, if a module is mutated for an apex X, then the
module will appear in the X-deps-into.txt file.

This change also changes the format of the txt file. It now clearly
shows why a module is included in the APEX by showing the list of
modules that depend on the module.

Jiyong Park d7536ba58d shared_lib dependency from a static lib crosses the APEX boundary
cc_library_static {
    name: "libfoo",
    shared_libs: ["libbar"],
}

cc_library {
   name: "libbar",
}

If libfoo is part of an APEX, then libbar is no longer considered as a
member of the APEX, because it isn't actually linked to libfoo.

To distinguish such a shared lib dependency from a static library from a
shared lib dependency from a shared library, a new dep type
SharedFromStaticDepTag is introduced. It is treated exactly the same as
SharedDepTag, except when we determine whether a dependency is crossing
the APEX boundary or not.

This allows us to check the apex_available property more correctly.
Previously, modules were incorrectly considered as being used for an
APEX due to the shared lib dependency from a static lib.

As a good side effect, this also reduces the number of APEX variants.
Specifically, on aosp_arm64, the number of the generated modules were
reduced from 44745 to 44180.

Jiyong Park 114ff53f5e m <apex_name>-deps-info prints the internal/external deps of the APEX
We need to have a way to see the list of modules that directly or
indirectly contribute to an APEX. People find it difficult to determine
whether a module is included in which APEXes because APEX tracks
indirect dependencies as well as direct dependencies. Therefore, just
looking at Android.bp for the APEX itself doesn't give the answer.

This change adds a new make target <apex_name>-deps-info, which
generates out/soong/<apex_name>-deps-info.txt file that shows the
internal and external dependencies of the said APEX.
Here, internal means the dependencies are actually part of the
APEX, while external means the dependencies are still external to the
APEX.
