light up sanitizers for ARM
...
You can expect the sanitizers to be built under any of the following conditions:
1) CMAKE_C_COMPILER is GCC built to cross-compile to ARM
2) CMAKE_C_COMPILER is Clang built to cross-compile to ARM (ARM is default target)
3) CMAKE_C_COMPILER is Clang and CMAKE_C_FLAGS contains -target and --sysroot

tsan: refactor storage of meta information for heap blocks and sync objects
...
The new storage (MetaMap) is based on direct shadow (instead of a hashmap + per-block lists).
This solves a number of problems:
- eliminates quadratic behaviour in SyncTab::GetAndLock (https://code.google.com/p/thread-sanitizer/issues/detail?id=26 )
- eliminates contention in SyncTab
- eliminates contention in internal allocator during allocation of sync objects
- removes a bunch of ad-hoc code in java interface
- reduces java shadow from 2x to 1/2x
- allows to memorize heap block meta info for Java and Go
- allows to cleanup sync object meta info for Go
- which in turn enabled deadlock detector for Go

Generalize StackDepot and create a new specialized instance of it to

origin history tree.
This reduces memory usage for chained origins roughly by an order of
magnitude.
Most importantly, this new design allows us to put two limits on
stored history data (exposed in MSAN_OPTIONS) that help avoid
exponential growth in used memory on certain workloads.
See comments in lib/msan/msan_origin.h for more details.

InstrProf: Support profiling dlopen'd shared libraries
...
Shared objects are hard. After this commit, we do the right thing when
profiling two separate shared objects that have been dlopen'd with
`RTLD_LOCAL`, when the main executable is *not* being profiled.
This mainly simplifies the writer logic.
- At initialization, determine the output filename and truncate the
file. Depending on whether shared objects can see each other, this
may happen multiple times.
- At exit, each executable writes its own profile in append mode.

These tests were XPASS-ing on Linux bots creating Mach-O, which makes
sense, since the real difference is the object format.
I'm hoping a short-term fix to get these tests passing on ELF is to
create two copies of the runtime -- one built with -fPIC, and one
without. A follow-up patch will change clang's driver to pick between
them depending on whether `-shared` is specified.

Use COMPILER_RT_EXPORT rather than COMPILER_RT_ABI for this function. Adding an

The .align statements in ARM assembly routines is actually meant to be a power

.p2align. .p2align is guaranteed to be a power-of-two alignment always and much
more explicit.
The .align in the case of x86_64 is byte alignment, use .balign instead of
.align.

Define CRT_HAS_128BIT even for PPC32
...
r201909, which introduced CRT_HAS_128BIT, unintentionally broke self-hosting on
PPC32. We used to define CRT_HAS_128BIT only on LP64 systems, but this is not
quite right (at least for Clang-compiled code). Even though __int128 is not
supported on PPC32, SROA can (and does) still form i128 variables at the IR
level, and operations on those variables may turn into the associated runtime
calls. As a result, we still need to compile __ashlti3, __ashrti3, __lshrti3,
and perhaps others, on PPC32.

[CMake] Use ExternalProject to build MSan-ified version of libcxx for unit tests.
...
This change lets MSan rely on libcxx's own build system instead of manually
compiling its sources and setting up all the necessary compile flags. It would
also simplify compiling libcxx with another sanitizers (in particular, TSan).
The tricky part is to make sure libcxx is reconfigured/rebuilt when Clang or
MSan runtime library is changed. "clobber" step used in this patch works well
for me, but it's possible it would break for other configurations - will
watch the buildbots.

[ASan] Fix coverage behavior when a PC belongs to an unknown address range.
...
This happens, e.g., when coverage data is collected for a module which is then
dlclose()'d. Currently this causes CovDump() to ignore all PCs that are greater
than the unrecognized PC. In other words, unloading a module causes ASan to
silently ignore any coverage data for modules loaded at higher addresses.
Instead we should just skip the unrecognized PCs.

[asan] enable LeakSanitizer (LSan) by default in asan. This only affects Linux x86_64. LSan has been used in various projects for more than half a year and we now consider it quite stable to be on by default.

[sanitizer] enable check_printf by default for asan and tsan. We've been using this flag for a while and it seems to be stable enough for the rest of the world.

[asan] add one more mode to run asan tests with '-with-calls', i.e. using -mllvm -asan-instrumentation-with-call-threshold=0. This is very unfortunate since it effectively doubles the number of gunit asan tests that need to be built and run, but as long as we need out-lined calls (PR17409) I see no other way to test this workaround

[ASan] Change AddressSanitizer.LoadStoreCallbacks to use asan_malloc and asan_free.
...
Interceptors don't really work on OSX in asan_noinst_test.cc (this is more or less intentional),
so one shouldn't call intercepted functions in this test -- added a comment about this.

[ASan] Replace a CHECK for mmap_limit_mb with a RAW_CHECK.
...
In the case of a CHECK failure the program tries to fork and launch llvm-symbolizer,
but hangs in mz_force_lock because one of the allocator locks is already acquired.
