0a468a4f3b rust: made-to-order rust staticlibs
Whenever any two Rust static libraries are included
as static libraries anywhere in a CC dependency tree, we sometimes
get duplicate symbol errors. To avoid this, we no longer
directly link multiple rust static libs to CC modules.

Instead, we build rust_ffi_rlib modules and produce the actual
static library that gets linked against the CC module based on
that CC module's full list of Rust rlib dependencies.

This introduces a new static_rlibs property for cc modules to
define the rust_ffi_rlib dependencies, which are then used to
generate the module above.

This CL is intended to deprecate rust_ffi_static. It leaves
rust_ffi_static and rust_ffi static variants in place until
the remaining rust_ffi_static declarations and uses can be
removed. In the meantime, rust_ffi_static produces
rust_ffi_rlib variants as well to make the transition easier.

004bd3f526 Revert "Split Rust crate builds into compile and link phases."
This reverts commit e7c71c344d.
The intermediates created by the separated rust compile steps are very
large, on the order of 60GB.  This is more than CI can support for now,
revert the split into compile and link phases.  This comes at the expense
of incremental build time, especially when modifying C/C++ sources that
are dependencies of rust modules.

a588d153c8 support sandboxed rust rules
This commit adds support for compiling rust rules inside the sbox
sandbox. To compile a rust module with sandboxing enabled, the entry
point to the crate must be specified via the `crate_root` property, and
all input sources and compile-time data must be specified via the `srcs`
and `compile_data` properties.

b6e6f99521 Add transitive shared libs to LOCAL_SHARED_LIBRARIES for rust modules
Rust modules are different from C++ modules in that they will install
their transitive shared libs alongside a binary. C++ modules don't
do this, you have to install the transitive shared lib manually. (but
they do install direct shared libs)

It does this by using InstallDepNeeded, a mechanism that adds
dependencies from installed files to the installed copies of
dependencies if InstallDepNeeded() returns true. This mechanism does
not end up tracking the installed files all the way to
FULL_SYSTEMIMAGE_DEPS.

We're attempting to make FULL_SYSTEMIMAGE_DEPS more accurate so that
we can track the files that should be installed properly, and remove
the need for `m installclean`.

Listing the libraries a binary uses in LOCAL_SHARED_LIBRARIES does
properly track them and end up listing them in FULL_SYSTEMIMAGE_DEPS.

4eeb2a9514 Remove dylibs prop from rust module types
For device build, rust defaults to dylib linkage for rustlibs deps. `dylibs` prop was provided for flexibility.

By removing it, we're enforcing users to either use the default linkage (dylibs for device and rlibs for host) or rlibs prop explicitly. This means no dylibs for host modules. This makes sense because host modules always uses rlib linkage against libstd. The flexibility with dylibs prop opened room for linkage collisions because the dependencies don't link against libstd the same way.

4df0257fe5 rust: Make dylib-std the canonical rlib form
This removes the dylib-std suffix from rlib variants which link against
libstd dynamically. This is by far the common case.

This fixes an issue where 'm <rust_library_rlib>' would fail since Make
would expect the suffix to be included (e.g. 'm libfoo.dylib-std').

e7c71c344d Split Rust crate builds into compile and link phases.
Teach rustc to generate object files instead of a linked executable
for binary and shared library crates. This lets us skip the lengthy
Rust compilation phase when only the C++ dependencies of these crates
have changed.

This works using a Python script that replaces the linker invoked by
rustc and converts the linker command line into a rspfile that can be
used during the link phase. The script makes certain assumptions about
how rustc invokes the linker, but since we control the version of Rust
we use, we can update the script if those assumptions ever break. I've
asked the Rust developers about adding an official way to do this so
hopefully we won't need to rely on this hack in the future.

The rustc rule for Kythe has been altered to pass linker=true, somewhat
consistent with the main rustc rule, which now doesn't invoke the actual
linker either. `m xref_rust` still succeeds, but hopefully we can find
someone who knows more about the rest of the Kythe pipeline who can let
us know whether it should still work. Otherwise, let's use this CL as
an opportunity to find out whether the rest of the pipeline is happy
with linker=true, since otherwise we will find it hard to maintain the
Kythe rule in the future.

8d10fc39af rust: Refactor stripped output file path
Rust installed files reside in "$MODULE_OUT/stripped/" when they are
stripped, otherwise they reside in "$MODULE_OUT". However, other parts
of Soong assume that installed files are always in $MODULE_OUT
(cc_modules place *unstripped* files in $MODULE_OUT/unstripped).

This notably causes problems when adding Rust modules as test data in
AndroidMkDataPaths. When Rust modules are parsed by AndroidMkDataPaths,
if they are stripped then they incorrectly get installed as test data
with the path:
<install_root>/<relative_install_path>/stripped/file.

This CL refactors how we handle Rust stripped output such that the
installed file always resides in $MODULE_OUT.

1921e8003d Rust cdylib/statliclib support for vendor snapshot.
Adds support for platform vendor_available Rust FFI libraries and
binaries to be included in the vendor snapshot.

Because rlib and dylibs are not yet in snapshots, libstd cannot be
included in a vendor snapshot. As a result, vendor-specific Rust code
can't be guaranteed to work with the platform-provided vendor_available
modules built with a newer toolchain. For now, a check is added
indicating vendor-specific Rust code is unsupported.

This changes the linkage for vendor variants of these modules to default
to rlib linkage since dylibs cannot be included in the snapshot yet.

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.

Annotate dependency tags for dependencies for which the

2b0811310e rust: Add libstd linkage mutator for rlibs.
The current state of linkage is that device targets always link
libstd dynamically except for rust_ffi_static which requires a static
libstd linkage. However this prevents producing rust_ffi_static
modules which depend on other Rust libraries as those dependencies
will link libstd dynamically and cause a collision. We also want our
rust_test modules to statically link in libstd as well.

This adds a linkage mutator for rlibs that creates a variant for each
libstd linkage. Dependent modules can then select the variant that
matches their linkage of libstd.

Also fixes an issue where installation paths were being generated for
rlibs and static libs even though they weren't being installed. This broke
when adding the linkage mutator as Make would complain about multiple
targets producing the same output.

Bug: 168729404
Test: rust_ffi_static module with other rustlib dependency can be built.

2093af23c0 [rust] Pass cc dependencies as linker flags.
In order to support cc dependencies which do not start with the 'lib'
prefix, we can't pass them through the -l flag. Instead, we can pass
them directly to linker flags.

Bug: 166151658
Test: cd external/rust/; mma
Test: cd external/crosvm/; mma
Test: Test linking to a cc dep that does not begin with 'lib'

26ecd6c597 [rust] Add SourceProviders as crates support.
This allows SourceProvider modules to create rust_library variants so
that generated source can be referenced as an external crate rather than
via an include macro. This is done by including rust_bindgen modules
like any other library, as a dependency in either rlibs, dylibs, or
rustlibs.

This renames the stem and flags properties for rust_bindgen modules to
source_stem and bindgen_flags, respectively. This deconflicts with the
usage in baseCompiler.

This also removes 'subName' from the Module struct and moves it over to
SourceProvider, which was the only user. This allows us to set it in
baseSourceProvider's AndroidMk; setting it in Module's AndroidMk was
causing problems finding NOTICE files for bindgen library variants.

Bug: 159064919
Test: New Soong tests pass.
Test: Local test rust_binary can use rust_bindgen module as a crate.

07cbaf4d89 Enforce correct variant usage for rust_bindgen.
Modules defined in the srcs property are automatically added as
dependencies with AddDependency(), which will use any variant available.
This can cause incorrect architecture bindings to be silently pulled in,
such as when a host module uses a rust_bindgen module that doesn't
create a host variant.

This moves populating depPaths.SrcDeps over to depsToPaths and adds a
check for SourceProviders to make sure the correct OS and architecture
is being used.

Bug: 161826371
Test: Soong no longer silently pulls in bindings for the wrong
      target.
Test: New Soong test to catch this case passes.

43845688bc Allow rust module dependency on SourceProviders.
Allow rust modules to depend on and use generated source code provided
by SourceProvider modules and genrule modules without resorting to
hardcoded output paths.

All generated sources are now copied to a dependent module's
intermediates directory, then OUT_DIR is set to point to that path when
calling rustc. This matches the common convention used in most rust
crates to include generated source code from the path defined in the
OUT_DIR environment variable.

A couple other small notable changes are included in this CL:

* prebuiltLibraries can no longer include generated source files as they
  should be prebuilt.
* srcPathFromModuleSrcs now excludes the main source file from the
  second return value so its a list of only the generated sources.

Bug: 159064919
