These are created by bp2build in /build/bazel/rules/apex. Eventually
these config_settings should likely be colocated with the source apex
definition.
Another alternative was to make Bazel's apex a macro that generates a
config_setting. I did not pursue this further for now since it requires the
apex_available of every allowlisted cc_library to also be allowlisted.
This might not always be true (e.g. com.android.runtime)

The default ELF segment alignment will be 4096. This alignment
can be overriden by setting the desired alignment in
PRODUCT_MAX_PAGE_SIZE_SUPPORTED flag. The alignment has to be
a multiple of the configured kernel page size.

If a library contributes to an API surface, it will have only a single
copy on device. Therefore, we should disallow installation to muliple
apexes/platform.
There are some exceptions to this rule today, and they have been relaxed
using allowlists.

Soong does not enforce apex_available on the contents of test apex. To
prevent special-casing test apexes in the apex validation aspect in
Bazel, drop the test apexes from the tags altogether.
( The core problem I am trying to solve is making sure that stub
libraries in Bazel have a single apex available. apex validation happens
to be a nice side benefit)

The core problem I am trying to solve is making sure that stub
libraries in Bazel have a single apex available. In Soong, this will be
enforced using some graph walk which is not easy to port to Bazel.
However, we might need to revisit this when we build the enforcement
mechanism in Bazel. We likely need a `test_for` on the top level
apex_test Bazel rule so that the test apex is _allowed_ to link against impl
of the library it is trying to test.
(This CL retricts this to cc_library, I can expand this to other modules
if this is the right approach.)

Currently, there is little verification around allowlisted modules
actually being mixed-built. This flag would allow us to verify
that a module allowlisted is mixed-built for at least one variant.

system libraries (libc, libm, libdl) belong to the runtime apex api
domain. platform and other apexes should link against stubs and not impl
of these libraries. Update bp2build so that both apex/non_apex picks
stubs. These axes need to be more granular in the future, but for now
this works because
- non_apex axis (platform) is a separate api domain than the runtime apex
- com.android.runtime which matches apex axis has not been allowlisted
yet.

We used to enable unique names only when a profile is available.
But A profile generated for a binary without unique names doesn't
work well when building a binary with unique names. To avoid a
chicken-and-egg problem, this CL enables the flag when afdo=true,
whether a profile exists or not.

only be added for CFI if `-fvisibility=hidden` is not already
specified. This will be achieved using toolchain features. Note
that Soong itself never adds `-fvisibility=hidden`. This is only
ever added in the `cflags` property of a bp file.

ld -r reorders symbols and invalidates the .llvm_addrsig section, which
then causes warnings if the resulting object is used with ld --icf=safe.
The warning is especially common when building with musl, as the
clang_rt.crt* objects have .llvm_addrsig sections, are linked into
libc_musl_crt* using ld -r, and are then linked into every other binary
and shared library with --icf=safe.
Strip the .llvm_addrsig section after ld -r to prevent the warnings.

The public stubs of libclang_rt.* originate from the same module. When
generating the Androidmk entries for these stubs, we need to add a
suffix to differentiate between the two stub variants.
This is likely an issue specific to libclang_rt.*. The public stubs of
other libraries like libc, liblog, ... come from a separate module
ndk_library which adds an .ndk suffix

again now bionic and ART have switched to gp. There's no need for a
corresponding "reserve gp" change because gp is automatically reserved.
