Evgeniy Stepanov b163f0276f [msan] Fix bad interaction between with-calls mode and chained origin tracking.
Origin history should only be recorded for uninitialized values, because it is
meaningless otherwise. This change moves __msan_chain_origin to the runtime
library side and makes it conditional on the corresponding shadow value.

Previous code was correct, but _very_ inefficient.

Daniel Sanders 4dc8a78b04 [asan] adding support of 32-bit address sanitizer for MIPS
Summary: The patch supports both the clang cross-compiler and native compiler

Patch by Kumar Sukhani <Kumar.Sukhani@imgtec.com>

Test Plan:
Kumar had the following asan test results when compiled on a MIPS board:

  Expected Passes    : 96
  Expected Failures  : 2
  Unsupported Tests  : 84
  Unexpected Passes  : 4
  Unexpected Failures: 19

The list of unexpected failures can be found in the review.

Evgeniy Stepanov df187feae4 [msan] Fix handling of multiplication by a constant with a number of trailing zeroes.
Multiplication by an integer with a number of trailing zero bits leaves
the same number of lower bits of the result initialized to zero.
This change makes MSan take this into account in the case of multiplication by
a compile-time constant.

We don't handle the general, non-constant, case because
(a) it's not going to be cheap (computation-wise);
(b) multiplication by a partially uninitialized value in user code is
    a bad idea anyway.

Constant case must be handled because it appears from LLVM optimization of a
completely valid user code, as the test case in compiler-rt demonstrates.

Alexey Samsonov e595e1ade0 Remove top-level Clang -fsanitize= flags for optional ASan features.
Init-order and use-after-return modes can currently be enabled
by runtime flags. use-after-scope mode is not really working at the
moment.

The only problem I see is that users won't be able to disable extra
instrumentation for init-order and use-after-scope by a top-level Clang flag.
But this instrumentation was implicitly enabled for quite a while and
we didn't hear from users hurt by it.

Clang's lit cfg already detects the currently selected SDK via
"xcrun --show-sdk-path". The same thing should be done for compiler-rt tests,
to make them work on recent OS X versions. Instead of duplicating the detection
code, this patch extracts the detection function into a lit.util method.

Evgeniy Stepanov 2be29929be Fix line numbers for code inlined from __nodebug__ functions.
Instructions from __nodebug__ functions don't have file:line

intrinsics (SSE and other) from <*intrin.h> clang headers _never_
have file:line information.

With this change, an instruction without !dbg metadata gets one from
the call instruction when inlined.

Fixes PR19001.

Reset coverage data on fork().

For normal mode, this reduces coverage dump size, because PCs from the parent
process are no longer inherited by the child.

3) CMAKE_C_COMPILER is Clang and CMAKE_C_FLAGS contains -target and --sysroot

Dmitry Vyukov bde4c9c773 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

efficiently (i.e. without duplicating stack trace data) store the
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.

Greg Fitzgerald 1733b5e263 XFAIL ptrace test on arm
The patch adds better target_triple and target_arch defaults for lit tests,
which allows us to XFAIL tests based on architecture.

Was:
  target_triple = LLVM_DEFAULT_TARGET_TRIPLE
  target_arch = HOST_ARCH

Now:
  target_triple = COMPILER_RT_TEST_TARGET_TRIPLE
                , otherwise LLVM_DEFAULT_TARGET_TRIPLE
  target_arch = first item in COMPILER_RT_TEST_TARGET_TRIPLE

Sergey Matveev 6cb47a083b [sanitizer] Support sandboxing in sanitizer coverage.
Summary:
Sandboxed code may now pass additional arguments to
__sanitizer_sandbox_on_notify() to force all coverage data to be dumped to a
single file (the default is one file per module). The user may supply a file or
socket to write to. The latter option can be used to broker out the file writing
functionality. If -1  is passed, we pre-open a file.

Saleem Abdulrasool 44a8c7233a profile: explicitly initialize file name in the test
The instrprofile-write-file-only test was failing on the builtbots.  The runtime
library initialization is explicitly being discarded to avoid the atexit hook.
However, this would also prevent the filename from being initialized.  Thus,
when the write file was invoked, the filename would not be setup, and the test
would fail as the profiling data would never be written out.  Explicitly
initialize the filename to ensure that the data is written out when requested.
This should hopefully finally get the build bots all green again.

Duncan P. N. Exon Smith 55e4d66f0c 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.

Duncan P. N. Exon Smith 870b77cd4d InstrProf: Create a PIC version of the profile runtime
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.

Duncan P. N. Exon Smith f6366cbeff InstrProf: XFAIL tests from r208940 on Linux
According to the buildbots, the new features for shared objects don't
work on ELF since it requires an -fPIC when building the profile
library.  XFAIL these tests for now.

It's possible we'll have to build two versions of the profile library on
Linux (one with -fPIC and one without), but it's not clear to me exactly
how to resolve this.

Change the API of the instrumented profiling library to work with shared

  - Most things are now declared hidden, so that each executable gets

  - Initialization hooks up a linked list of writers.

  - The raw format with shared objects that are profiled consists of a
    concatenated series of profiles.  llvm-profdata knows how to deal
    with that since r208938.
