0007d810e2 Change bool, and string properties to *bool, and *string for cc
there's no use case for prepending/appending to bool, and string
properties within module struct. Declearing "*bool" and "*string" almost
cover everything user need.

I did see one case that user specify relative_install_path as
path prefix in cc_defaults, and concatenate with the one in real module
to get the final relative install path in Android.bp <bionic/tests/libs>.

87dd963ace Remove no_default_compiler_flags property
no_default_compiler_flags is only used by the crt* modules,
is unnecessary, and causes problems when necessary flags like
-no-canonical-prefixes are not passed.  Remove the property.

Use useVndk() instead of noDefaultCompilerFlags() to determine
if adding libc as a dependency is necessary and won't cause a
circular dependency.

d4b484b070 Build system changes for CFI (Soong)
This CL makes multiples changes in preparation for platform-wide CFI.

(a) Adds a second -version-script=... to the command line
when building components that use a version script. This ensures that
__cfi_check is also exported, and allows CFI to be enabled for these
components.

(b) Adds both topdown and bottom up mutators for CFI to help propagate
dependencies correctly for components that may need CFI disabled.

(c) Fixes an issue with the mutators to correctly apply settings to
both generated variants

(d) Fixes issues when components have more than a single visibility
flag.

2a45412445 LLNDK can re-export headers
Added export_llndk_headers properties to llndk_library module. And a new

// frameworks/native/libs/arect/Android.bp
llndk_headers {
    name: "libarect_vendor_headers",

llndk_library {
    name: "libnativewindow",
    ....
    export_llndk_headers: ["libarect_vendor_headers"],
}

check that
-Iframeworks/native/libs/arect/include is in LOCAL_EXPORT_CFLAGS of

294356f045 Automatically reorder C/C++ link dependencies in Soong
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

Test: reorder the entries of static_libs in an Android.bp and see that linking still succeeds

6a43f04777 Squash vendor sources before linkageMutator runs
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.

82e2bf3b7f vendor_available:false hides a lib from vendors
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.

49b53d5c7c Explicitly link the profile runtime during PGO
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.

ada83ec0a6 Add PGO support to soong
Bug: http://b/63768402
Bug: http://b/65598278

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

c77a0b3f9c Extract the linker and embed it into host bionic binaries
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.

a4fce191ba Dump abi for vendor variants of VNDK libraries.
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.

d4e641b6e9 <Hermetic> Replace Soong Python bootstrap process with embedded
launcher.

For Python2, we bundle embedded launcher as bootstrapper within every
.par file. This feature is only enabled for linux_x86_64 for now. We
provide a user flag: hermetic_enabled within bp file. By default, Pyhon2
still use classic bootstrapping way to construct .par file and relys on
host interpreter. Once embedded_launcher is enabled, launcher will be
used to bootstrap .par file and execute user program.

For Python3, the launcher will be ready soon, and for now it still relys
on classic bootstrapping.

Test: Real example is used to test.

ba090d16c2 Add LTO support to soong
Enabling the lto property for a module builds that module and all static
dependencies with LTO.

LTO (link-time optimization) allows the compiler to optimize and
generate code for the entire module at link time, rather than
per-compilation unit. LTO is required for Clang CFI and other
whole-program optimization techniques. LTO also allows cross-compilation
unit optimizations that should result in faster and smaller code, at the
expense of additional compilation time.

8effde47de Install VNDK libs in /system instead of /vendor
If BOARD_VNDK_VERSION is set, and a module is set to
`vendor_available: true` it is installed in /system and /vendor.

However, if the module is a VNDK library, it must be
installed at `/system/${LIB}/vndk` instead of /vendor/${LIB}.
For those modules, need following to set.

vendor_available: true,
vndk: {
    enabled: true,
    support_system_process: true,
},

`support_system_process` is optional to define.
If it is defined to true, the module is regarded as vndk-sp.

link-type check for VNDK modules is added to make sure that VNDK
modules only link to other VNDK shared libraries or LL-NDKs.

move the ABI checks to VNDK from all of vendor_available.

Test: Copied the linked abi dumps produced by mm -j64 in bionic/libc to
prebuilts/abi-dumps/ndk and gzipped them. Ran mm -j64 again in
bionic/libc and verified header-abi-diff getting invoked.

10d2231d44 Check reused source files in hasSrcExt
hasSrcExt is used to determine extra flags and dependencies when
generated files are used.  If the generated files are being handled
in a static library whose objects are reused in a shared library,
the flags and dependencies still need to apply.  Instead of clearing
the source files in the shared library, move them to an OriginalSrcs
property, and check that in hasSrcExt along with the Srcs property.

Also pass extra exported include directories from the static
library to the shared library.

3e231fd8bd Add header-abi-checker for Vndk abi checks.
header-abi-dumper: dumps abi exported by source files for Vndk.
header-abi-linker: links abi dumps produced by header-abi-dumper.
header-abi-diff: compares linked dumps.

Test: mm -j64 showcommands > make_log in bionic/libc.
      This produced linked dumps in out/soong/.intermediates.
      Copied these dumps to
      prebuilts/abi-dumps/ndk/current/arm64/source-based/.
      Changed the abi and re-ran mm -j64 showcommands > make_log
      confirmed that the build reported compatibility breakge without
      actually failing (advisory mode).

4416e5db69 Split /system and /vendor modules, allow multi-installation
Nothing changes if BOARD_VNDK_VERSION isn't set.

When the VNDK is enabled (BOARD_VNDK_VERSION in Make), this will split
/system and /vendor modules into two different variant spaces that can't
link to each other. There are a few interfaces between the two variant
spaces:

The `llndk_library` stubs will be available in the /vendor variant, but
won't be installed, so at runtime the /system variant will be used.

Setting `vendor_available: true` will split a module into both variants.
The /system (or "core") variant will compile just like today. The
/vendor ("vendor") variant will compile against everything else in the
vendor space (so LL-NDK instead of libc/liblog/etc). There will be two
copies of these libraries installed onto the final device.

Since the available runtime interfaces for vendor modules may be
reduced, and your dependencies may not expose their private interfaces,
we allow the vendor variants to reduce their compilation set, and export
a different set of headers:

  cc_library {
      name: "libfoo",
      srcs: ["common.cpp", "private_impl.cpp"],
      export_include_dirs: ["include"],
      target: {
          vendor: {
	      export_include_dirs: ["include_vndk"],
	      exclude_srcs: ["private_impl.cpp"],
	      srcs: ["vendor_only.cpp"],
	  },
      },
  }

So the "core" variant would compile with both "common.cpp" and
"private_impl.cpp", and export "include".

The "vendor" variant would compile "common.cpp" and "vendor_only.cpp",
and export "include_vndk".

1dd8839286 Refactor sanitized library on-disk layout - Soong.
This CL moves the location of ASAN-ified libraries on disk in the
following manner:
/data/lib* --> /data/asan/system/lib*
/data/vendor/* --> /data/asan/vendor/*

There are a couple of advantages to this, including better isolation
from other components, and more transparent linker renaming and
SELinux policies.

c31994825a Fix include order
Include order should be module includes, dependency exported includes,
and then global includes.  Module includes and global includes are
computed during compileFlags, but dependency exported includes are
not handled until later.  Move the global includes into a new
flags variable so that the dependency includes can be appended
to the module includes.

11b261472a Rework vndk detection
Instead of having a module define `use_vndk: true`, assume that we're
building with the VNDK if we're installed on the vendor partition, and
BOARD_VNDK_VERSION==current. This now matches our behavior in Make.

Once BOARD_VNDK_VERSION!=current, we'll need to disable modules that
need to otherwise compile against the VNDK, since we can only compile
against the current VNDK.

Test: build.ninja for aosp_arm is the same before/after
Test: Ensure there are no boards that set BOARD_VNDK_VERSION
