Currently, we are depending on a platform default in rustc's
android_base module to keep unwind tables generated. That default was
configured specifically to change the behavior for Firefox profiling
purposes prior to the existence of the override flag. As a result,
there's no structural reason the default will remain as is.

Allows defining data binaries and libraries that should be installed
alongside a rust_test module, similar to cc_test.
This refactors cc_test as well so it can define rust_ffi_shared and
rust_binary modules as data.

Test: New Soong tests pass.
Test: Example module installs data appropriately.

The 'fuzzer' sanitizer enables 'hwasan', which is not supported for Rust
static binaries. Make sure we skip applying this sanitizer to those
binaries.

On HWASAN global sanitized builds, fuzz targets had hwasanFlags applied
twice. Rust only allows llvm-args flags to be passed in once however, so
this broke compilation.

rust_bindgen calls are missing a large set of -D cflags which control
how headers are interpretted for certain variations (such as
-D__ANDROID_VNDK__). This CL introduces the full set of these flags.

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.
Bug: 171710847
Test: Installed files now always reside in $MODULE_OUT

Write toc files that list the exported symbols so dependents are
only rebuilt if the exported symbols change.
This exports the CC function TransformSharedObjectToToc, and also
removes an unused arg from its signature.

This CL adds Rust support for the SANITIZE_TARGET options.
This CL includes a couple small fixes to related to HWASAN, ASAN,

additional llvm-args are passed to ensure that HWASAN-ified Rust/C
interop works correctly.

This just sets up the toolchain and allows Darwin+Arm64 to be specified
as a HostCross target. These variants will not be exported to Make, or
be installed on a Soong-only build. A future CL will add support for
universal binaries using these variants.
This config is a bit stranger than the regular 64/32 multilib, as it's
two primary 64-bit configs. And on a Darwin/X86 machine, the Arm64
versions are HostCross (doesn't work on the current machines), while a
Darwin/Arm64 machine, either version works (if Rosetta is installed).

Structs embedding binaryDecorator (rust_test, rust_benchmark, rust_fuzz)
are binaries as well, but won't pass checks against *binaryDecorator,
such as the check in StaticExecutable().
Add a binaryInterface that can be checked instead to simplify these
checks and ensure we catch all binaries.

Thin LTO provides similar performance gains to full LTO but takes less

Rust fuzzers were not packaging up their CC shared dependencies.
This would lead to fuzzers using the shared libraries included on
system, which may not be sanitized, leading to incorrect behavior.
This refactors the relevant code from CC and calls it from the Rust
build logic.

It's an error if a rust module's srcs is empty. Prior to this change
the output was a panic that complains loudly about a slice error and
nothing else. This change doesn't stop the panic, but at least adds
a bit of context so devs who make a simple mistake can more easily
fix it.

This change makes the installation routine for rust be similar to that
of cc. Previously, rust.baseCompiler.install() (which internally calls
android.ModuleContext.InstallFile()) was not called when the module is
not installable. Although this may sound right at first glance, it is a
behavior different from that of cc and prevents an uninstallable rust
module from being packaged into a packaging module like
android_filesystem. This is because the packaging happens inside
InstallFile().
Fixing the issue by following the behavior of cc modules; Call
HideFromMake() or SkipInstall() when a rust module is not installable,
but call InstallFile() as long as the output file is valid.
InstallFile() internally skips the installation (but the packaging) when
HideFromMake() or SkipInstall() was called.
