Peter Collingbourne e5ba28648f build: Link the unwinder dynamically into platform and vendor binaries.
Instead of linking the unwinder statically into every binary, link it
dynamically, by exporting the symbols from libc.so. This has a number
of advantages:

- Reduces image size (system.img size decreases by 1.7MB on walleye-userdebug,
  and 1.2MB on crosshatch-userdebug).
- Allows us to easily change/upgrade the unwinder throughout the system,
  including vendor prebuilts.
- Allows code outside of libc++ to define custom personality routines.
  Previously, personality routines would call the unwinder routines in the
  local binary, which would cause problems with unwinders with global state
  (such as the libgcc unwinder) if the copy of the unwinder used for unwinding
  (normally libc++'s copy) were different from the copy linked against the
  personality routine.

Colin Cross 4af21ed26f Split local and global cflags
Native compiler flags are currently applied in approximately:
global cflags
local cflags
local include dirs
global include dirs
global conlyflags
local conlyflags
global cppflags
local cppflags

This means that a flag that is enabled in the global cppflags
cannot be disabled in the local cflags, and an Android.bp author
must know to disable it in the local cppflags.  A better order
would be:
global cflags
global conlyflags
global cppflags
local cflags
local conlyflags
local cppflags
local include dirs
global include dirs

We are mixing both the global and local cflags into a single
variable, and similar for conlyflags and cppflags, which
prevents reordering them.  This CL prepares to reorder them
by splitting the global and local cflags into separate variables.

Ivan Lozano 52767be335 Add support for Rust C libraries.
Adds the ability for rust modules to be compiled as C libraries, and
allows cc modules to depend on these rust-generated modules. This also
means that soong-rust should not have any dependencies on soong-cc aside
from what's required for testing.

There's a couple small fixes included as well:

 - A bug in libNameFromFilePath that caused issues when library's had
 "lib" in their name.
 - VariantName is removed from rust library MutatedProperties since this
 was unused.

Bug: 140726209
Test: Soong tests pass.
Test: Example cc_binary can include a rust shared library as a dep.

Ryan Prichard b49fe1bde7 Stop linking libdl.a into static bins
libdl.a has a no-op dlopen, which breaks static libraries that need a real
dlopen. Instead of automatically linking libdl.a into static executables,
make it optional.

Until recently, the libunwind_llvm.a unwinder, used on arm32, needed the
no-op dladdr, but it's now built using -D_LIBUNWIND_USE_DLADDR=0.

The HWASan run-time uses dlsym and dladdr, so add a libdl dependency for
HWASan-built static binaries. We could also remove the dependency from
libclang_rt.hwasan_static-*.a, but this is also easy to do.

Bug: http://b/141485154
Test: bionic unit tests, device boots, verify that static and dynamic
   executables can throw/catch an exception
Test: verify that a static executable using dlopen doesn't link (unless it
   adds an explicit dependency on libdl)

Colin Cross f7a17daefe Use -nostdlib++ instead of -nodefaultlibs
Host builds using libc++ used -nodefaultlibs to turn off the default
C++ runtime, and then added back all the other necessary libraries.
Clang supports -nostdlib++ since https://reviews.llvm.org/D47115
that removes the C++ runtime without affecting the other default
libraries.  Use -nostdlib++, and remove the lists of default
libraries.

2019-08-23 00:15:08 +00:00
Pete Bentley 99f2fc27e6 BoringSSL FIPS build - introduce extraLibFlags and use for STL libs.
Rationale: On non-bionic, stl.go currently adds system libraries to
ldFlags, this causes problems for partialLd rules.  However adding the
same libraries to libFlags breaks some existing modules due to symbol
conflicts as the system libraries are linked before some module code.

Introduced a general mechanism for adding libraries to be linked
last rather than making this STL-specific.

Pirama Arumuga Nainar a403cc7254 Change STL for Windows to libc++.
- Stop including libstdc++ headers.
- '-pthread' and 'static-libgcc' are unused when we pass -nodefaultlibs.
We didn't pass -nodefaultlibs for libstdc++.
- Use SjLj exceptions for 32-bit.  libgcc_eh implements SjLj exception
model for 32-bit.
- Disable visibility annotations for libcxx and libcxxabi since we are
only going to support these as static libraries.
- Use Win32 threads.  MinGW pthreads throws an error when building
libcxx since it's pthread_mutex_initializer is not constant (needs a
cast).
- Link libgcc_eh, which needs pthread, which in turn depends on
kernel32.  Wrap the libraries with --start-group and --end-group and
remove duplicates.

Test: Build and test Windows binaries under Wine.

Ryan Prichard b1703659a8 Use Soong modules for the NDK's extra STL libraries
* The extra STL libs are:

       libc++abi.a [needed for ndk_libc++_static]
       libandroid_support.a [always needed in NDK r16]
       libunwind.a [needed for ARM32]

 * The existing STL-dependency logic in linkShared only applies to shared
   libraries. By moving it to STL deps, the extra STL libs are linked into
   both shared libraries and executables.

 * Remove the ndk_prebuilt_library/ndkPrebuiltLibraryFactory module type,
   which is unused now.

 * Reuse the ndk_prebuilt_static_stl module type to describe the extra
   static libraries that are linked with both the static and shared libc++
   STLs.

Dan Albert a07b84598f Disable availability macros in libc++ on Darwin.
libc++'s headers are annotated with availability macros that indicate
which version of Mac OS was the first to ship with a libc++ feature
available in its *system's* libc++.dylib. We do not use the system's
library, but rather ship our own. As such, these availability
attributes are meaningless for us but cause build breaks when we try
to use code that would not be available in the system's dylib.
