How it works:
1. build/make/core/Makefile generates a txt file with the kernel
version, which is taken from an explicit BOARD_KERNEL_VERSION value,
or extracted from the kernel image on the source tree, or extracted
from the kernel image extracted from the prebuilt boot.img.
The file is saved at
$ANDROID_PRODUCT_OUT/obj/PACKAGING/check_vintf_all_intermediates/kernel_version.txt.
2. If PRODUCT_ENABLE_UFFD_GC is "default", meaning the GC type needs to
be determined by the kernel version, build/make/core/Makefile copies
kernel_version.txt to
out/soong/dexpreopt/kernel_version_for_uffd_gc.txt.
3. build/soong/dexpreopt/config.go writes the the UFFD GC flag to
out/soong/dexpreopt/uffd_gc_flag.txt. The flag is determined by an
explicit PRODUCT_ENABLE_UFFD_GC value or by contruct_uffd_gc_flag.py,
which reads kernel_version_for_uffd_gc.txt and determines the flag
accordingly.
4. dex2oat takes the UFFD GC flag from uffd_gc_flag.txt.
5. post_process_props.py mangles ro.dalvik.vm.enable_uffd_gc based on
the same logic.

Api levels annotations flags should respect the stubs type, but the
everything api versions xml file was being passed to the metalava

This change fixes such issue by setting api versions xml file (passed to

We obtain credentials for RBE through gcloud in case of builds on glapstations (i.e., glinux workstations at home). Hence gcloud needs to be able to run during the build for this credential fetching to work.

crt_pad_segment adds a NOTE to the ELF which is used by the binoic
loader to determine whether it should pad segments when mapping them
into the virtual address space, such that there are no gaps between
mappings of consecutive segments. This avoids an increase in
unreclaimable kernel slab memory usage for VMAs on devices where the
runtime-page-size > elf-segment-p_align.
Since -fandroid-pad-segment [1] respects -nostdlib used in android
platform builds, soong must link in crt_pad_segment to platform shared
libraries.
For simplicity, link crt_pad_segment everywhere that crtend_so is
applicable, ignoring nocrt property, as there is no other reason
to track these separately.

LLNDK will not be finalized at the same time with NDK and APEX
libraries. The ABI dumps need to be generated and stored separately.
In lsdump_paths.txt, each dump path is tagged with LLNDK, NDK, etc. A
library may have multiple dumps with different tags. The finalization
scripts will read lsdump_paths.txt and select the dumps for LLNDK.
LLNDK versioning for trunk stable has not been implemented. Currently
the dumps for LLNDK, APEX, NDK are identical.

For prebuilts, the dexpreopt rules of system server jars are now
generated from the context of the top-level prebuilt apex and not in the
context of the shim java_import modules. Since
`dex_preopt.profile_guided` property is defined in java_import, this
needs to be bubbled up to the top-level apex. This will be done using
deapxerInfo. If profile_guided of a transitive java_import is true, the deapexed .prof file will be
set as dexreopter.inputProfilePathOnHost before invoking
dexpreopter.dexpreopt. This ensures that only that java_import undergoes
profile guided dexpreopt, and not every other transitive java_import

Even when building stubs from source, the rules for the
java_api_library modules are generated although they are not
executed. This leads to NPE, as setting `WITHOUT_CHECK_API=true`
prevents `checkCurrentApiTimestamp`, which the java_api_library modules
depend on, from being generated.
To prevent the NPE, this change prevents the `checkCurrentApiTimestamp`
from being registered as the dependency of the java_api_library modules
when `WITHOUT_CHECK_API=true` is set.

This CL is the java_(test_)_import equivalent of aosp/2928483.
With trunk stable, we will have
multiple prebuilts of the prebuilt java .jars in
prebuilts/module_sdk/art/<v>/test-exports/, and this CL introduces a

Implementation details: Create a new source_module_name property to
identify the root module. rdeps referring to the root module will get
redirected if necessary. This property also
becomes the stem, if `stem` is not set explicitly.

For prebuilts, java.dexpreopt gets called twice
1. in the context of the top-level prebuilt apex
2. in the context of the java_library shim
Only the artifacts of (1) get installed. The artifacts generated by 2)
are unused. However the args used to generate the artifacts of (1) are
incorrect. It uses moduleName(ctx) to do special-handling of apex system
server jars. This special-handling does not happen in (1), so although
dexpreopt artficats get generated, they get generated with the wrong
args.
To fix this, add an additional parameter in java.dexpreopt to pass the
libraryName explicitly.
Details
- Delete moduleName function. This was used to determine the java
library name, which is no longer safe
- Add a libraryName parameter to java.dexpreopt
- Most module types will use j.Name() as libraryName
- prebuilt_apex and apex_set will iterate over its `contents` and use
each element as libraryName when invoking java.dexpreopt
With the correct args passed from (1), we can drop j.dexpreopt from (2)
completely. Dropping (2) also breaks profile guided dexpreopt tests.
These currently operate on (2). They will be moved to (1) in the next CL
of this stack.
