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.
Example:
❯ readelf -WS /system/lib64/libc++.so [Output simplified]

Current VNDK prebuilts are disabled if BOARD_VNDK_VERSION is not set,
but VNDK prebuilts should be enabled even BOARD_VNDK_VERSION is not set
because VNDK APEXes should be available from VNDK deprecation. This
change removes some restrictions on VNDK prebuilts to enable those from
VNDK deprecation.

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.

This CL is scoped to cc_* module types. With trunk stable, we will have
multiple prebuilts of the cc modules in
prebuilts/module_sdk/art/<v>/host-exports/, and this CL introduces a
mechanism to use apex_contributions to select a specific versioned
prebuilt when building.
If a soong module is selected using apex_contributions, all rdeps will
get that soong module, which includes
- rdep soong modules which might be depending on it via Android.bp
- Soong's rule builder HostToolPath API
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.

Although vendor modules can be built bundled, they are technially not
part of the "platform", as it cannot access platform libraries (system
partition) directly.
They can only link to a restricted set of platform libraries (LLNDK),
and access restricted set of APIs.
We used to derive the LLNDK API level from the VNDK version. However
after VNDK deprecation, there is no "VNDK version" anymore.
Instead we would just derive the value from platform SDK version:
* If building an in-development build, build vendor modules against the
in-development "current" API level.
* If building a REL / Final build, vendor should target the latest
stable API.

No-one ever fixes unused-* or deprecated-* warnings in external/ (nor should they!).
-Wno-deprecated-enum-enum-conversion should probably have been added
next to -Wno-deprecated-anon-enum-enum-conversion when it was added,
since it's a major spam contributor, and equally unlikely that anyone
will clean them up.
-Wno-deprecated-dynamic-exception-spec is a weird special case because
it should be irrelevant after our next libc++ update, but in the
meantime -- because libc++ is used everywhere -- this is a massive spam
contributor that no-one on Android cares about because we don't use
exceptions (and the people seeing this can't fix libc++ anyway).

The previous patch was insufficient. Craig Topper explains:
-fno-vectorize only disables the loop vectorizer
-fno-slp-vectorize only disables the SLP vectorizer
The backend can also use vector instructions for memcpy/memset or
combining multiple scalar loads and/or stores. That is independent
of -fno-vectorize.
-mllvm -vector-bits-min=0 will disable any use of fixed vectors. And
will make attribute(vector_size) get scalarized.
-mno-implicit-float will disable both vectorizers and
prevent the backend for using vectors for memcpy/memset
oor multiple scalar loads/stores. It will not affect
attribute(vector_size). -mno-implicit-float also prevents scalar
floating point instructions from being used for anything that didn’t
use float/double/_Float16/etc. type in source, but I don’t think that
happens on RISC-V today. 32-bit X86 can use a 64-bit x87 FP load as an
atomic load for uint64_t, for example. Basically -mno-implicit-float
is supposed to prevent the compiler from using FP or vectors when the
source doesn’t explicitly use FP or vectors.
So -mno-implicit-float was what we were actually looking for here. I've
done a clean build with this change, and see only the expected
(hand-written assembler) vector code in bionic, and the ART
ClassLinker::LoadClass() issue is gone too. As far as I can tell, the
remaining vector code is all deliberate in that sense.
We may still end up back here again, to change "gcv" to "gc", but that
still requires some code changes just to build, and still makes it less
obvious that this is just a temporary workaround for a qemu bug
(specifically https://gitlab.com/qemu-project/qemu/-/issues/1976).
