This reverts commit 2370af0e23.
Reason for revert: New Build Breakage: aosp-master/aosp_arm64_ab-userdebug @ 4376965
Change-Id: Ibe4b819c4292457c454bf42e6d94fba3071ec04b
libm is a default library for device builds, so default it for host
builds as well.
Also removes duplicate additions of -ldl, -lpthread, -lm and -lrt.
Test: m host
Change-Id: I8f7e799d48a1f427e48dcfb1d0ccba93c5f9780b
Make sure that libdl is always after libc on the command line.
Simplifies the logic to always support system_shared_libs for
sdk and vndk builds.
For backwards compatibility without updating lots of Android.bp
files, allow libdl to be listed in shared_libs as long as it
is also in system_shared_libs or libc is not in system_shared_libs.
Remove all the places that libdl is added as a dependency, since
it will always be present unless explicitly removed now.

It's never anything except nil, and it unnecessarily complicates
the implementations.

This CL blocks modules intended for the host from having the bottom up
sanitizer mutator applied. We only maintain a single copy of host
binaries, so generating variants doesn't make sense
anyway. Additionally, the existing logic was causing an error with
builds not embedded in make (eg: aosp-build-tools which uses
soong_ui.bash) where the wrong variant was installed on the host. This
change should fix that.
Bug: 64536751
Test: m -j40 && SANITIZE_TARGET="address" m -j40
Test: aosp-build-tools build breakage is fixed.
Change-Id: Ia79b4661f69ce26a7be17c4339c18ca0f397d760
This CL fixes a bug in the ASAN top down mutator which was incorrectly
checking (and setting) SanitizeDep to true only for the parent module
and not for the visited child modules.
Fixing this also requires some changes to the variant creation logic
to ensure that the correct variant is passed to make for
installation. This will eventually be replaced by logic that appends
an appropriate suffix to sanitized libraries (eg: libc++.asan), which
will allow both variants to be passed to make.

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).
Bug: 37480243
Test: BOARD_VNDK_VERSION=current m -j <name> is successful, where <name>
is one of the vendor-only libraries in Soong. (i.e.
android.hardware.renderscript@1.0-impl)
Test: m -j does not break anything

Ubsan is currently support ARM/ARM64,
so It's OK to enable the build Flag
Test: build test module with flags in Android.bp:
sanitize: {
all_undefined: true,

Change-Id: I37a01b4610132f58315e68335b3c3cdfb148357d
Add support for excluding paths from having integer_overflow applied to
them when using SANITIZE_TARGET=integer_overflow via an
INTEGER_OVERFLOW_EXCLUDE_PATHS make variable. This covers the soong side
of the change.
Bug: 30969751
Test: Build with SANITIZE_TARGET=integer_overflow
SANITIZE_TARGET_DIAG=integer_overflow
INTEGER_OVERFLOW_EXCLUDE_PATHS=<path> and confirmed this was no
longer being applied to binaries in that path.
Change-Id: I298b772f5425da28dff1cf007825be19558db3a8
Adds the SANITIZE_TARGET=integer_overflow build option to apply signed and
unsigned integer overflow sanitization globally. This implements the
Soong side of the build option.
An additional build option is provided to control whether or not to run
in diagnostics mode, controlled by SANITIZE_TARGET_DIAG. This works the
same way that SANITIZE_TARGET does and currently only supports
'integer_overflow' as an option.
A default sanitizer blacklist is added to avoid applying sanitization
to functions that are likely to exhibit benign overflows.
Bug: 30969751
Test: Building with and without the new flags, device boot-up, tested
various permutations of controlling the new flags from build files.
Change-Id: Ibc8a8615d3132f1a23faaf1cb4861f24c5ef734a
Update the coverage sanitizer flags in soong to use the new
flavor of coverage sanitization.

Test: Fuzzer runs with coverage guards.

Add a list of flags which are not understood by clang LibTooling tools
and filter them out of the Cflags the tools are invoked with.
Test: In frameworks/av, make libmedia vendor_available (this invokes
header-abi-dumper on this module), mm -j64.

Change-Id: I46f017212b89f4331145c999103d0ed44da0abaf
Setting Sanitize.Diag.Undefined to true does not enable diagnostics for
all possible UBSan sanitizers that might be declared in Sanitize.Misc_undefined
(specifically unsigned-integer-overflow and nullability-*). This adds an
equivalent Sanitize.Diag.Misc_undefined string array to allow diagnostics to
be enabled in these sanitizers.
Bug: 62546512
Test: make works and device boots.
Test: Tested an Android.bp generated binary with the new field enabling
unsigned-integer-overflow diagnostics.
Change-Id: I9aa7cb2555ab4f94ae1aa290715a617718d936ff
Also filter out -Wl,--no-undefined for all host sanitizers, not just ASan.
UBSan on host defaults to no-trap (i.e. diagnostic mode), and that requires
the runtime library and runs into the same problem with undefined symbols as ASan.
Bug: 34719251
Test: Misc_undefined: ["integer"] on a soong target

This CL disables CFI if both CFI and ASAN flags are enabled. This
allows ASAN to take precedence where needed, preventing build errors
that would otherwise arise.

Test: SANITIZE_TARGET="address" m -j40
Change-Id: Id336bf2bf5498d4c3ea6492e36b366c76c06376e
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.

CFI enabled components need ar to use the gold linker. This CL adds
that.

Test: Enabling CFI for a Soong component builds without error.
Change-Id: Icbf78fa1ca0d845350516b4dd345b54fbb7ef847
Adds the -fsanitize-blacklist option for CFI, using the built in
blacklist at external/compiler-rt/lib/cfi/cfi_blacklist.txt.
Also refactors the CFI cflags and ldflags into cc/makevars.go to
ensure they're consistent across Soong and make projects.
Bug: 30227045
Test: ENABLE_CFI=true m -j40 builds and boots.
Test: The blacklist prevents runtime errors that otherwise occur.

This CL disables CFI for 32-bit ARM processes, which is broken due to

With SANITIZE_TARGET="address coverage", if a module disables ASan
(address: false), it is left with just coverage, which is not
supported. In that case, disable coverage as well.

Change-Id: Idcd04dad8cab7c7e2644d2408b1b8a381490e5af
This CL ensures that locally enabling CFI in a .bp file is not honored
unless it is enabled globally using ENABLE_CFI=true first, effectively
hiding it behind a flag.

Allow specifying one or more architectures to sanitize for. Defaults to

Host builds were compiling without -Wl,--no-undefined because of an ASAN

Host builds may build binaries that must have ASAN disabled. Convert
host ASAN to use variants. Since there is only one install location for
