This uses knowledge of transitive dependencies to reorder
linker command line arguments such that if module A depends
on module B, then module A is automatically listed before
module B in the linker command line.
This should mostly remove the need for Android.bp files to
list all of their static dependencies in link order
Bug: 66260943
Test: reorder the entries of static_libs in an Android.bp and see that linking still succeeds

This property defaults to 'true' and setting it to false skips profile
use. This escape hatch lets us disable PGO for a module without
completely removing the 'pgo' property. Additionally, this also helps
selectively disabling PGO for some architectures, if desired.
Test: Test that -fprofile-use is not added for a test module if
'enable_profile_use: false' is set.

linkageMutator removes srcs property of the shared variant of a lib in
order to reuse *.o files compiled for the static variant also to the
shared variant.
However, this causes problem when vendor-specific srcs are specified in
target: {vendor: {srcs: ["..."]}}. For example, let's assume
cc_library {
name: "libfoo",
srcs: ["foo.c"],
target: {
vendor: {
srcs: ["bar.c"],
},
},
}
Then,
static_vendor: inputs = foo.o, bar.o
shared_vendor: inputs = foo.o (from static_vendor), bar.o (from
static_vendor), bar.o
So, bar.o is included twice and this causes multiple symbol definition
error.
In order to handle the problem, vendor mutator is applied before the
linkage mutator and the vendor-specific srcs are squashed in the vendor
mutator.

When a lib is explicitly marked as `vendor_available: false`, then it
can't be directly depended by a vendor lib which is installed to /vendor
partition. This is to hide some VNDK libs (including llndk) from vendors
so that platform owners can have a freedom of modifying their ABI
without breaking vendors.
In addition, the list of the private libs are exported to the make world
as VNDK_PRIVATE_LIBRARIES.
Also, fixed a bug that allowed a vndk lib to link against to vendor
library (or vendor variant of a system lib) if the lib is prebuilt.
Bug: 64730695
Bug: 64994918
Test: Add `vendor_available: false` to libft2 and libcompiler_rt.
Add the libs to shared_libs property of a vendor library in soong

Bug: http://b/65598278
The profile runtime depends on libgcc for some symbols (only under some
circumstances - armv5, ndk r14, static executables). Since Android
build passes -nostdlib and adds libgcc manually, the profile runtime
gets passed to the linker later than libgcc.
Instead, explicitly add the profile runtime to the linker command (and
pass one other flag added by the clang driver to the link).
Test: Build a library with profile instrumentation that otherwise fails
instrumented build.

target.linux_glibc will apply to host builds with glibc, which is
identical to the current target.linux. In a future change, target.linux
will change to affect all targets using the Linux kernel (android,
linux_bionic, and linux_glibc).
target.bionic will apply to all OS variants using Bionic.

Add support for the 'pgo' property to specify how a module is processed
under PGO. A sample property is below:
pgo: {
instrumentation: true, // could be "sampling: true" when supported
profile_file: "pgo_simple.profdata",
benchmarks: ["pgo_simple"],
}
1. Runtime profiles can be gathered using "sampling" or
"instrumentation". Sampling is not supported initially.
2. If 'toolchain/pgo-profiles' project is found,
'toolchain/pgo-profiles/${profile_file}' is passed to the compiler and
linker when building this module.
3. If ANDROID_PGO_INSTRUMENT environment variable is set, and includes a
benchmark in the 'benchmarks' list, appropriate flags (for e.g.
-fprofile-generate for instrumentation) are passed to the compiler and
linker when building this module.
Test: Add example modules that specify the pgo property and verify
appropriate flags and dependencies in the Ninja file. Some
tests/examples are in https://android-review.googlesource.com/474805

The linux kernel requires that the ELF interpreter (runtime linker)
that's referenced by PT_INTERP be either an absolute path, or a relative
path from the current working directory. We'd prefer a relative path
from the binary, similarly to how we handle looking up shared libraries,
but that's not supported.
Instead, extract the load sections from the runtime linker ELF binary
and embed them into each host bionic binary, omitting the PT_INTERP
declaration. The kernel will treat it as a static binary, and we'll use
a special entry point (linker_wrapper) to fix up the arguments passed by
the kernel before jumping to the embedded linker. From the linker's
point of view, it looks like the kernel loaded the linker like normal.

Bionic headers aren't implicit when building with the VNDK, they're
exported from libc. So add libc to the shared libraries of a cc_object

Currently, abi is dumped for platform variants of system libraries.
Dump them for vendor variants since they are the ones which need to be abi
stable on security updates. This also ties abi dumping to BOARD_VNDK_VERSION.
Test: For libfoo:
1) Added a source file with a dummy function for the core
variant.
2) Excluded the source file from the vendor variant.
3) BOARD_VNDK_VERSION=current mm -j64 produces libfoo.so.lsdump with no
dummy_function since the source file was not included in the vendor
variant.
Test: Inspected build.ninja and confirmed that all of a library's abi
dump dependencies (.sdump files are dependencies of the final .lsdump files) are
from vendor variants.
