9da9d49ede Only depend on a single file for generated headers
While the rule may really need all of the generated header files to
exist, only one of them (per genrule task) needs to be in the dependency
list, since the rest are essentially aliases.

This brings an AOSP aosp_arm-userdebug out/soong/build.ninja file from
372MB to 156MB, with equivalent functionality. The Android-aosp_arm.mk
file is reduced from 11MB to 6.5MB.

7e53c57ed6 Disable inlining and loop unrolling in LTO without PGO profile
Such optimisations may significantly increase the binary size when
compiler heuristics are off. Disabling these helps cut down the
binary sizes with negligible decrease in performance, but allows us to
be more comfortable enabling LTO across various projects.

51be632b95 Fix llvm-ar error caused by using lto and sanitizer together
LLVM-AR does not allow passing --plugin options more than once. The
--plugin ARFLAGS that lto want to add, may already exist if sanitizer is
also turned on.

Fixed this by adding a new bool Flags.ArGoldPlugin. Set this variable to
true whenever LLVM gold plugin is needed for ArFlags. In function
TransformObjToStaticLib(), add this option to arFlags using global value
${config.LLVMGoldPlugin} if the bool value is true.

f351174107 Support VNDK extensions
This commit adds `extends: "name"` property and provides basic support
to VNDK extensions.  This is the simplest example:

```
cc_library {
    name: "libvndk",
    vendor_available: true,
    vndk {
        enabled: true,
    },
}

cc_library {
    name: "libvndk_ext",
    vendor: true,
    vndk: {
        enabled: true,
        extends: "libvndk",
    },
}
```

A vndk extension library must extend an existing vndk library which has
`vendor_available: true`.  These two libraries must have the same
`support_system_process` property.

VNDK-ext libraries are installed to `/vendor/lib[64]/vndk` and
VNDK-SP-ext libraries are installed to `/vendor/lib[64]/vndk-sp` by
default.

If there is a matching abi-dumps in `prebuilts/abi-dumps`,
`header-abi-diff` will be invoked to check for ABI breakages.

2db7692a74 Add [soc|device|product]_specific
Added three properties (soc_specific, device_specific, and
product_specific) that shows what a module is specific to.

`soc_specific: true` means that the module is specific to an SoC
(System-On-a-Chip) and thus need to be installed to vendor partition.
This has the same meaning as the old `vendor: true` setting.

`device_specific: true` means that the module is specific to the entire
hardware configuration of a device includeing the SoC and off-chip
peripherals. These modules are installed to odm partition (or /vendor/odm
when odm partition does not exist).

`product_specific: true` means that the module is specific to the
software configuration of a product such as country, network operator,
etc. These modules are installed to oem partition (or /system/oem when
oem partition does not exist). These modules are assumed to be agnostic
to hardware, so this property can't be true when either soc_specific or
device_specific is set to true.

5beccee92c Split logtags implementations for cc and java
Logtags files in cc and java are treated fundamentally differently.
In cc, they are not used for compiling at all, but need to be passed
to Make to be combined into the global logtags list, and logtag files
are listed in a logtags property.  In java they are listed in srcs
and produce generated code that is compiled in, and so shouldn't
also need to be listed in a logtags property.

Move the logtags property to cc and export it to Make from there,
and have java extract logtags files from srcs to be exported to
Make.

7154928c93 Install VNDK snapshot libraries for system build
When BOARD_VNDK_VERSION := <VNDK version>, or
PRODUCT_EXTRA_VNDK_VERSIONS includes the needed <VNDK version> list,
the prebuilt VNDK libs in prebuilts/vndk/ directory will be
installed.

Each prebuilt VNDK module uses "vndk_prebuilt_shared" for shared
VNDK/VNDK-SP libs.

Following is the sample configuration of a vndk snapshot module:
vndk_prebuilt_shared {
    name: "libfoo",
    version: "27",
    vendor_available: true,
    vndk: {
        enabled: true,
    },
    arch: {
        arm64: {
            srcs: ["arm/lib64/libfoo.so"],
        },
        arm: {
            srcs: ["arm/lib/libfoo.so"],
        },
    },
}

The Android.bp for the snapshot modules will be auto-generated by a
script.

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.

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.

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.

Test: make -j12 libc with lto: true for libc

27b188bc86 .vendor suffix is added only for libs having core/vendor variants
When the lib is vendor-only, then .vendor suffix is not added.
Furthermore, this change correctly adds .vendor suffix even to the names
listed in LOCAL_SHARED_LIBRARIES so that we don't need to add the suffix
in the make world.

This also allows us to use the original name (without the .vendor
suffix) of the vendor-only modules in make (e.g. in PRODUCT_PACKAGES or
as a make target).

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.

4c35af09ea fix: a vendor variant of a lib doesn't re-export llndk headers
If a vendor (or vendor_available) lib has a dependency to a llndk
library, the name of the llndk library is modified to <name>.llndk.

There was a bug that this name modification is done only for shared_libs
property, but not for export_shared_lib_headers property. As a result,
the headers of the llndk was not re-exported. Fix the bug by modifying
export_shared_lib_headers property as well.
