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

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.

device_kernel_headers is a built-in heder-only lib that provides device-specific
kernel headers. The header path is configured via a new product variable
SystemIncludeDirs, which is currently the mirror of
TARGET_PROJECT_SYSTEM_INCLUDES in the make world.
Note: generic kernel headers (bionic/libc/kernel) have been added to the
include path by default. "device_kernel_headers" module is for device-specific
kernel headers such as /device/*/*/kernel-headers.
Note 2: this is opt-in for Android.bp modules (i.e. header_libs :
["device_kernel_headers"] required.) while it is always provided to
Android.mk modules.

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".

Shared libraries are now installed to different directories depending on
their types.
* NDK libraries: /system/lib/ndk
* VNDK libraries: /system/lib/vndk
* VNDK-ext libraries: /system/lib/vndk-ext
* Framework-only libraries: /system/lib
* Vendor-only libraries: /vendor/lib
* Same-process HALs: /vendor/lib/sameprocess
In addition, a new module type vndk_ext_library is added. It is almost
identical to cc_shared_library but it introduces another attribute
'extends'. This is use to reference the vndk library that this vndk-ext
library is extending.
For example, in order to extend a vndk library libFoo:
cc_library {
name: "libFoo",
srcs: [...]
}
---------------------
vndk_ext_library {
name: "libFoo-extended",
srcs: [...]
extends: "libFoo"
}
Then, libFoo will be installed as /system/lib/vndk/libFoo.so and
libFoo-extended will be installed as /system/lib/vndk-ext/libFoo.so.
Note that file name of the latter is libFoo.so, not libFoo-extended.so:
file name of an extending module is automatically set to that of the
extended module.

This is configured the same as make -- a global NATIVE_COVERAGE=true
flag to allow native coverage, then COVERAGE_PATHS=path1,path2,... to
turn it on for certain paths.
There are .gcnodir files exported to Make and saved in $OUT/coverage/...
files which are `ar` archives containing all of the compiler-produced
.gcno files for a particular executable / shared library.
Unlike the Make implementation, this only passes links the helper
library (automatically through --coverage) when one of the object files
or static libraries being used actually has coverage enabled.
Host support is currently disabled, since we set -nodefaultlibs, which

Right now this mostly just copies what Make is doing in
build/core/ninja.mk and build/core/soong.mk. The only major feature it
adds is a rotating log file with some verbose logging.
There is one major functional difference -- you cannot override random
Make variables during the Make phase anymore. The environment variable
is set, and if Make uses ?= or the equivalent, it can still use those
variables. We already made this change for Kati, which also loads all of
the same code and actually does the build, so it has been half-removed
for a while.
The only "UI" this implements is what I'll call "Make Emulation" mode --
it's expected that current command lines will continue working, and
we'll explore alternate user interfaces later.
We're still using Make as a wrapper, but all it does is call into this
single Go program, it won't even load the product configuration. Once
this is default, we can start moving individual users over to using this
directly (still in Make emulation mode), skipping the Make wrapper.
Ideas for the future:
* Generating trace files showing time spent in Make/Kati/Soong/Ninja
(also importing ninja traces into the same stream). I had this working
in a previous version of this patch, but removed it to keep the size
down and focus on the current features.
* More intelligent SIGALRM handling, once we fully remove the Make
wrapper (which hides the SIGALRM)
* Reading the experimental binary output stream from Ninja, so that we
can always save the verbose log even if we're not printing it out to
the console

For every file which we can run clang-tidy (C/C++ clang-built), we add a
new build node that depends on the object file (since clang-tidy does

on or off without needing to rebuild the object files.

This compresses multiple files in parallel, and will split up larger
files (5MB+) into smaller chunks (1MB) to compress in parallel.
There is a small size overhead to recombine the chunks, but it's only a
few bytes per chunk, so for a 1MB chunk, it's minimal.
Rough numbers, with everything in the page cache, this can compress
~4GB (1000 files) down to 1GB in 6.5 seconds, instead of 120 seconds with
the non-parallel soong_jar and 150 seconds with zip.
Go's DEFLATE algorithm is still a bit worse than zip's -- about 3.5%

This doesn't do any decompression / recompression, but just copies over

rewriting of the paths.
The first expected usecase is to replace img_from_target_files during

zip2zip -i <target-files.zip> -o <img.zip> OTA/android-info.txt:android-info.txt IMAGES/*:.
Except it decompresses and recompresses the images, which takes over a
minute instead of a few seconds.

Some checks for common errors with user-provided compiler and linker
flags:

the make definition and use the value from Soong.

a property was set in a blueprints file.

Instead of using this hardcoded list, use the blueprint plugin
infrastructure to find them at build time and load them.

Allow modules to vary their properties based on product variables.
For now, DEVICE_USES_LOGD, DEVICE_USES_JEMALLOC, and DEVICE_USES_DLMALLOC,
and BOARD_MALLOC_ALIGNMENT are supported.
Product variables can provide a value (only bool and int supported for
now), and if any of the product variable properties contains a "%d"
then Sprintf will be called with the property value as the format
and the product variable value convert to an int as the only argument.
For example:
product_variables: {
dlmalloc_alignment: {
cflags: ["-DMALLOC_ALIGNMENT=%d"],
},
},
will cause -DMALLOC_ALIGNMENT=16 to be added to any top level
properties called "cflags".

Instead of putting all the blueprint registrations in soong_build,
put them all in init() functions. This puts the registration next
to the implementation.

During mutation, make deep copies of the blueprint modules, then start
modifying the property lists to apply the static/shared properties.

Translation is getting complicated because the expressions supported
by Blueprint are difficult to support in Make. Modify androidbp
to use context aware parsing so it can evaluate all expressions at
parse time, so it only needs to deal with constant values.

Build a map of blueprint directory to modules built from that
directory, and then add phony rules to build.ninja that emulate
the behavior of mma in the current build system.
Also fixes checkbuild to depend on checkbuild files and installable
files, but not installed files.

Rename module definition files to Android.bp to avoid conflicts
with another project called Blueprint.
