Michal Gorny 4e9e939b4f [cmake] [asan] Remove unnecessary gtest dep from dynamic tests
Remove the redundant dependency on 'gtest' target from the dynamic tests
in non-MSVC environment. The tests reuse compiled objects
from ASAN_INST_TEST_OBJECTS, and therefore they have been built against
gtest already.

This both fixes the spurious dependency on 'gtest' target that breaks
stand-alone builds, and brings the dynamic tests more in line with
regular tests which do not pass this dependency
to add_compiler_rt_test() through generate_compiler_rt_tests().

Michal Gorny 007b540feb [cmake] [interception] Remove duplicate gtest from test COMPILE_DEPS
Fix the gtest dependency to be included in DEPS only, rather than
in COMPILE_DEPS + DEPS. The former variable is apparently used to
provide unconditional dependencies, while the latter are only used
for non-standalone builds. Since they are concatenated, specifying gtest
in both is redundant. Furthermore, including it in COMPILE_DEPS causes
build failure for standalone builds where 'gtest' target is not present.

Kostya Kortchinsky 8d4ba5fd23 [scudo] Allow for non-Android Shared TSD platforms, part 1
Summary:
This first part just prepares the grounds for part 2 and doesn't add any new
functionality. It mostly consists of small refactors:
- move the `pthread.h` include higher as it will be used in the headers;
- use `errno.h` in `scudo_allocator.cpp` instead of the sanitizer one, update
  the `errno` assignments accordingly (otherwise it creates conflicts on some
  platforms due to `pthread.h` including `errno.h`);
- introduce and use `getCurrentTSD` and `setCurrentTSD` for the shared TSD
  model code;

for the sanitizer allocator but *not* for the Scudo allocator.

Hence, this changeset introduces a new ReservedAddressRange object to

Kostya Kortchinsky 6a45f9ce82 [sanitizer] Move the errno/ENOMEM allocator checks logic to separate .cc
Summary:
This is a new attempt at D38706, which had 2 issues.

The first one was that it broke TSan, because `sanitizer_errno.h` was not
directly included in `tsan_mman.cc`. This fixes the include.

The second one was that it broke the nolibc build, because `__errno_location`
couldn't be found. This adds the new .cc to the libcdep list instead of the
base one.

Kostya Kortchinsky 03f9e76790 [sanitizer] Move the errno/ENOMEM allocator checks logic to separate .cc
Summary:
The fact that `sanitizer_allocator_checks.h` is including `sanitizer_errno.h`
creates complications for future changes, where it would conflict with `errno.h`
definitions on Android and Fuchsia (macro redefinition).

By moving the portion that sets errno in the checks to a separate compilation
unit, we avoid the inclusion of the header there, which solves the issue.

Not that it is not vital to have that function in a header as it is called as a
result of an unlikely event, and doesn't need to be inlined.

Whenever possible (Linux + glibc 2.16+), detect dynamic loader module by

matching approach fails on some configurations.

Dean Michael Berris 8dcba551d9 [XRay][compiler-rt] Write out arg1 payload in naive mode logging
Summary:
This change allows the XRay basic (naive) mode logging implementation to
start writing the payload entries through the arg1 logging handler. This
implementation writes out the records that the llvm-xray tool and the
trace reader library will start processing in D38550.

This introduces a new payload record type which logs the data through
the in-memory buffer. It uses the same size/alignment that the normal
XRay record entries use. We use a new record type to indicate these new
entries, so that the trace reader library in LLVM can start reading
these entries.

Depends on D38550.

Summary:
This change moves cxx-abi library in asan/ubsan/dd link command line

cxx-abi may be the full libstdc++/libc++, it makes sense for it to be
ahead of libc and libgcc, at least.

The real motivation is Android, where in the arm32 NDK toolchain
libstdc++.a is actually a linker script that tries to sneak LLVM's
libunwind ahead of libgcc's. Wrong library order breaks unwinding.
