29e95d94bf Move copy rule for system server jars from dexpreopt_gen to makefiles.
This is necessary in order to expose the copy rule to Ninja. Otherwise
Ninja has a build rule that depends on the copied jar (namely, dexpreopt
commands for all subsequent system server jars that have the current one
in class loader context), but no rule that creates it, so Ninja fails
with a "no rule to make ..." error.

The change only affects system server ed in Android.mk

Previously the problem existed, but was hidden by the fact that the only
system server jar defined in Android.mk was the last one on the list, so
no other jar depended on it. Now that updatable apex jars are also
dexpreopted (https://r.android.com/1828115) the problem was uncovered.

ca9bc98e0c Preopt APEX system server jars.
The path to the artifacts will in the form of
/system/framework/oat/<arch>/<encoded-jar-path>@classes.{odex,vdex,art},
where <encoded-jar-path> is the path to the jar file with "/" replaced
by "@". For example,
/system/framework/oat/x86_64/apex@com.android.art@javalib@service-art.jar@classes.odex

There will be a follow-up CL to update ART runtime to recognize
artifacts in that path.

0b1c70efbc Don't add uses_libs/optional_uses_libs to the manifest_fixer.
These properties specify libraries that cannot be implicitly inferred by
Soong. If these properties are added to Android.bp, this can only be for
the reason that there is a <uses-library> tag in the manifest which is
unknown to the build system. Adding them to the manifest_fixer doesn't
make sense: if they are not in the manifest, they should be removed from
Android.bp as well.

Ulya Trafimovich
fc0f6e34ce Fix the way manifest fixer detects optional <uses-library> entries.
Previously manifest_fixer used a naive way to distiniguish optional libs
from required ones: it checked if a library is on the list of optional
compatibility libraries. This works for compatibility libs, but not for
other libs.

Now we properly track optionality through all stages of the build,
starting with the addition of the library as a dependency (here's where
the `uses_libs`/`optional_uses_libs` distinction kicks in), store it in
dependency tag and propagate to class loader context, and from there to
the manifest_fixer.

The tests have been updated accordingly.

aa3c355820 eng builds: dexpreopt: stop explicitly removing minidebuginfo
This special-casing is actively unhelpful nowadays, as it breaks
callstack unwinding and symbolisation by tools that work using the
on-device debug info (e.g. perfetto's profilers). It's also highly
surprising that eng builds have less debug info than userdebug/user.

As far as I can tell, the history behind this case is (with some
internal-only references as the context is in the review comments): the
minidebuginfo was originally rolled out in device-specific makefiles
(e.g. ag/2433691). Eng builds were excluded, presumably due to time/size
concerns for rebuild+resync workflow, as well as the assumption that
engineers using eng builds already have the necessary debug info
off-device. Later, as some more makefile variables were introduced, the
conversation in ag/990059 shows that the overheads were no longer a
concern, and the last patchset generalised the option to include eng
builds. However at a later point, during device-specific makefile
cleanup, the eng-exclusion got restored: ag/2455645. This then ended up
in the makefile->soong transition, leaving us with the current special
casing that is undesireable.

Checking things with an internal master build on my workstation:
dexpreopting system services is 10s regardless of this minidebuginfo
flag, and the resulting odex size is 37MB vs 38MB. Overall, I only see 4
dexpreopt invocations as part of a local build, so the effect of this
patch should be negligible.

840efb6661 Don't attempt to add stub libraries to class loader context.
A Java module may depend on a stub library. In that case an additional
dependency on the implementation library is created, and it is used to
add the implementation library to class loader context. We should not
attempt to add the stubs library as well (previously the attempt to add
it happend after the implemention was added to CLC, to the attempt was
unsuccessful).

Raise an error if someone tries to add the same library with different
build/instal paths.

Also, rename local variable `implicitSdkLib` to `sdkLib` to better
reflect its meaning.

Ulya Trafimovich
69c1aa94ac Drop "prebuilt_" prefix when adding libraries to class loader context.
This is needed when some source libraries get replaced with prebuilt
variants: CLC should contain one entry for a library (the prebuilt one
or the source one, whichever of them is preferred). Because the prebuilt
module name starts with "prebuilt_" prefix, previously Soong considered
such libraries as two different ones libraries and added both to CLC.

0e4ccebb16 Don't fail if the target module is disabled in dex2oat tool
dependencies.

dexpreopt.RegisterToolDeps runs late after prebuilt dependencies have
been resolved, and there's special code in dex2oatPathFromDep to
resolve the prebuilt from the source module. However, if the source
module is disabled then the dependencies check in validateAndroidModule
will complain, so we need to disable that check in this particular
situation.

Also add a comment to explain why dexpreopt.RegisterToolDeps needs to
run so late.

For running dex2oat on the target_files, the paths should be use the
device install path instead of the path starting with $(OUT).
So add usesTargetFiles option and basePath option which indicates
extracted path. With those options, the path is replaced with
$(basePath)/$(device path)

And also, add DexPreoptImageDeviceLocations in the config which refers
to the boot image path(without arch) on the device. Because
DexPreoptImage related device path was missing.

dd622951a4 Fix AAPT path in dexpreopt.
Dexpreopt uses AAPT to parse `targetSdkVersion` from the manifest, so it
the generated dexpreopt.sh script that calls AAPT must depend on it,
otherwise AAPT might not be built by the time it is used. Tool
dependencies are handled via the global Soong config and the
DEXPREOPT_GEN_DEPS variable that Soong generates for Make. This config
always uses Soong tool paths, like out/soong/host/linux-x86/bin/aapt
rather than out/host/linux-x86/bin/aapt.

This CL fixes a mistake in dexpreopt rule that used context-dependent
AAPT path (so, when called from Make, the dependency was on Soong tool,
but a Make tool was actually used, so it failed sometimes).

9023b02c00 Allow using updatable boot jars in dexpreopt (but don't use them yet).
This CL handles updatable boot jars in the same hacky way as we handle
non-updatable boot jars: it creates a set of predefined paths to the dex
jars in a global config, then traverses all modules in a singleton
context, finds updatable boot jars and adds copy rules from these jars
to the predefined paths. A proper way would be to register dependencies
of the dexpreopted modules on the boot jars and extracting paths to dex
files by walking these dependencies.

bd6b076f80 Allow modules that don't run verify_uses_libraries to have nonempty CLC.
There are modules that would have passed verify_uses_library check, but
don't run it for some reason (the check gets enabled either with an
explicit setting, or if the module has nonempty <ues-library> lists in
the build properties). Previously all such modules were assumed to have
empty CLC, which is not always true. In particular, compatibility
libraries are ignored, which affected e.g. Calendar and messaging apps.

This CL gives such apps a chance to have correct CLC. The goal for the
future is to enforce verify_library_check by default.

4fced5582d Support test fixtures in dexpreopt package
The tests in dexpreopt are unit tests that don't require the use of
test fixtures but there are a number of tests in java and apex packages
that need to configure dexpreopt behavior so this changes adds support
for modifying the dexpreopt configuration in test fixtures.

4a13acb07d Use compiler filter "verify" for dexpreopt w/o class loader context.
In cases when class loader context cannot be computed at build time and
verify_uses_libraries check is relaxed (RELAX_USES_LIBRARY_CHECK=true)
dexpreopt uses a special compiler filter that suppresses AOT-compilation
to native code and applies only those optimizations that do not require
class loader context. Previously the "extract" filter was used. Now ART
supports using "verify" filter in this configuration.

8c35fcf4d5 Add non-fatal mode for verify_uses_libraries check.
The new mode is enabled with environment variable
RELAX_USES_LIBRARY_CHECK. If the variable is set to true, then a
verify_uses_libraries check failure does not fail the build, instead it
sets a special compiler filter "extract" for dexpreopt, which means that
the DEX file will be extracted, but it won't be compiled to native code.
Class loader context will be set to empty in this case (not &, as it is
going to be deprecated soon).

If the variable RELAX_USES_LIBRARY_CHECK is unset or set to something
other than "true", then the old behaviour of the verify_uses_libraries
check is preserved.

The intended use case for this flag is to have a smoother migration path
for the Java modules that need to add <uses-library> information in
the build files. The flag allows to quickly silence build errors. This
flag should be used with caution and only as a temporary measure, as it
masks real errors and affects performance.

verify_uses_libraries check is reworked so that it writes the error
message to a status file (which is used instead of the former timestamp
file). Currently the stored error message is not used, but it may be
used later to produce a warning. Dexpreopt command checks if the status
file exists and is nonempty; if that is the case, then compiler filter
is set to "extract".

Test: Manually add some mismatch between the libraries in the Android.bp
      and Android.mk files for dexpreopted apps, build with
      RELAX_USES_LIBRARY_CHECK=true and obsserve that the build doesn't
      fail and they are compiled with compiler-filter "extract".
      Unset RELAX_USES_LIBRARY_CHECK and observe that the build fails.

65556a87d3 Preserve <uses-library> order in dexpreopt.config files.
Library order is important because it is used to construct class loader
context, which is then written into OAT/ODEX files and chacked against
class loader context constructed by PackageManager on the device. If the
orders are different, dexpreopted code is rejected.

Soong avoids using Go maps for class loader context representation
precisely for that reason. However, for the modules defined in makefiles
dexpreopt configs were serialized to JSON and unmarshaled to Go maps,
which resulted in wrong order of libraries. This CL changes Go
representation of class loader contexts imported from JSON and makes the
order stable.
