Colin Cross 31076b3185 Move stubs related methods out of LinkableInterface
The stubs methods are very specific to cc for now, move them out
of LinkableInterface so they are not shared with rust.  Instead,
create a cc.Module.library field that contains the libraryInterface
to simplify calling libraryInterface methods on cc modules.

Colin Cross 0de8a1e17b Start using Providers instead of direct module access
Export information about static libraries, shared libraries and
exported flags through Providers instead of accessing the module
directly.  Much more is left to be converted, but this significantly
simplifies the dependencies on libraries with stubs by making it easy
for a module to masquerade as another by simply exporting the
providers from the other module.  Instead of depending on all the
versions of a library and then picking which one to use later, it
can depend only on the implementation variant and then select the
right SharedLibraryInfo from the variant.

Thiébaud Weksteen d458745f15 cc: export Stripper struct
The cc stripping logic can be reused for Rust. Export the Stripper
structure for that purpose. Extract the strip-related flags from
builderFlags into StripFlags. Add the method flagsToStripFlags
(similarly to flagsToBuilderFlags).

Add the helper method disableStripping on libraryDecorator.

Colin Cross 82e192c3ae Add sdk mutator for native modules
Compiling native modules against the NDK disables platform features
like ASAN.  For anything shipped on the system image there is no
reason to compile against the NDK.  Add a new mutator to Soong that
creates a platform and an SDK variant for modules that set
sdk_version, and ignore sdk_version for the platform variant.  The
SDK variant will be used for embedding in APKs that may be installed
on older platforms.  Apexes use their own variants that enforce
backwards compatibility.

Yi Kong c49c393f73 Repack libgcc.a to only include required objects
Previous solution by using objcopy uses a quirky behaviour of the GNU
objcopy and there is no equivalent option in llvm-objcopy.

Instead of removing symbols, extract and repack libgcc to only include
required objects.

Ryan Prichard f979d73428 Omit .gnu_debuglink sections in object files
I'm not sure if these sections are used, but by adding them to
libgcc_stripped.a, we can end up with multiple .gnu_debuglink sections in
an executable, where the first two unhelpfully point at "libgcc.a". e.g.:

$ readelf -SW -x.gnu_debuglink out/target/product/walleye/system/bin/bootstrap/linker64

Yi Kong acee27cd72 Strip libgcc to only keep fallback symbols
We use libgcc as fallback for symbols not present in libclang_rt
builtins, however we didn't know what exact symbols were being used,
some may not be intended to fallback.

Create libgcc_stripped, which only contains unwind symbols from libgcc.

Patrice Arruda ea3fcdffc2 Soong: Add synopsis to several modules under the cc package.
Added synopsis to the following modules under cc package:
    * llndk_headers
    * llndk_library
    * vendor_public_library
    * toolchain_library

Bug: b/128337482
Test: Generated the documentation and verified that the synopsis was
added to each of the module.

Pirama Arumuga Nainar 65c95ff1fb Include libprofile-extras to all coverage variants
Bug: http://b/128524141

Include libprofile-extras (defined in system/extras/toolchain-extras) to
all modules that need a coverage variant.  Also add
'-uinit_profile_extras' when linking with coverage.  This causes the
setup code in libprofile-extras to be linked into binaries/libraries
with coverage enabled.

We add the static library to the non-coverage variants as well but is a
no-op for them (since the '-u...' flag is not added for them).

Adding this dependency creates several circular dependencies since
coverage variants were being created for other module types that never
had any compilation or linking done during the build.  This change stops
creating coverage variants for toolchain_library, cc_prebuilt_library_*,
cc_library_headers module types (by adding a function to the linker
interface to specify whether native coverage is enabled).

Dan Willemsen 742a5453c2 Remove `clang: false` support
Most everything in Soong is using clang (and we're getting very close
for Make as well), so remove the ability to select GCC to build a
module.

We still need to keep the internal functionality around to find libgcc.a
and other toolchain_library modules with GCC.

Nan Zhang 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>.
