Filipe Cabecinhas 3121ddf7fa [asan] Move scariness_score_test.cc to a common subdirectory
Summary:
Only one of the tests in it doesn't work on OS X.
On Windows it seems that everything that is being moved is also
supported.

The abort() test wasn't copied over (original case 22). This is because
it doesn't work on OS X.

Commit r280364 has introduced some call-graph optmisations making a profiler

across functions. This commit works around the issue, leaving the origial

Dean Michael Berris f50eb93da7 [compiler-rt][XRay] Initial per-thread inmemory logging implementation
Depends on D21612 which implements the building blocks for the compiler-rt
implementation of the XRay runtime. We use a naive in-memory log of fixed-size
entries that get written out to a log file when the buffers are full, and when
the thread exits.

This implementation lays some foundations on to allowing for more complex XRay
records to be written to the log in subsequent changes. It also defines the format
that the function call accounting tool in D21987 will start building upon.

Once D21987 lands, we should be able to start defining more tests using that tool
once the function call accounting tool becomes part of the llvm distribution.

Adhemerval Zanella 1005b7d90c msan: Enable 48-bit VMA support on aarch64
This patch adds 48-bits VMA support for msan on aarch64. As current
mappings for aarch64, 48-bit VMA also supports PIE executable. The
48-bits segments only cover the usual PIE/default segments plus some
more segments (262144GB total, 0.39% total VMA). Memory avaliability
can be increase by adding multiple application segments like 39 and
42 mapping (some mappings were added on this patch as well).

Tested on 39 and 48-bit VMA kernels on aarch64.

Akira Hatanaka 1164cae527 [asan] Mark asan-symbolize-sanity-test.cc as UNSUPPORTED on x86_64-apple
and x86_64h-apple.

Mark the test as UNSUPPORTED to fix a bot that is failing.

http://lab.llvm.org:8080/green/job/clang-stage2-configure-Rlto_check

The bot is failing because asan_symbolize.py cannot tell whether the
reported address is from an x86_64 slice or an x86_64h slice by the
length of the address alone, so it ends up passing the wrong arch to
atos.

Chris Bieneman 5968c3ac1f [CMake] Add check-compiler-rt target for runtimes build
Durning standalone builds (which includes runtimes builds) we want to create a target named check-compiler-rt. Additionally we also create check-all if it doesn't already exist as a convienence target that depends on check-compiler-rt.

This allows us to generate a single check target that invokes lit for all test suites in the runtimes projects, while avoiding name collision of check-all and not breaking existing workflows.

It fails if the clang's default target is not X86.

The proposed patch adds an additional requirement for the X86 target to the test, making lit ignore the test if the target is different.

Daniel Sanders 875671185e [mips] Remove obstack.cc XFAIL added in r278504 since it broke X86 and PPC somehow.
Adding the XFAIL has caused msan to report a different line number in the call

at first glance since it's the line that uses uninitialized memory rather than
the first non-whitespace line of the file but this needs investigating.

The mips64el compiler-rt build has recently been enabled. XFAIL the failing

The two asan tests require the integrated assembler. This will be fixed soon
for Debian mips64el but not for any other mips64el targets since doing so
requires triple-related issues to be fixed..

has already been posted for this).

Evgeniy Stepanov 851378831e [asan] abort_on_error=1 by default on Android.
With this change, the default behavior on error is to call abort()
instead of _exit(). This should help the OS to capture a tombstone of
the error.

RAM usage of the lit test suite goes up because of all the tombstone
gathering, so I'm limiting the parallelism of the test target.
Previously it was based on the number of the CPUs on the host
machine, which is definitely wrong.

  * These all differ from LIT's current behaviour.
  ** People's expectations vary depending on whether they know that LIT does a

This patch adds "target-is-${target_arch}" to the available features list and
updates the mips XFAIL's to use them. XFAIL'ing on these features will
correctly account for the target being tested. Making the table:

Summary:
Adds a new, generic, resizing hashtable data structure for use by esan
tools.  No existing sanitizer hashtable is suitable for the use case for
most esan tools: we need non-fixed-size tables, parameterized keys and
payloads, and write access to payloads.  The new hashtable uses either
simple internal or external mutex locking and supports custom hash and
comparision operators.  The focus is on functionality, not performance, to
catalyze creation of a variety of tools.  We can optimize the more
successful tools later.

Adds tests of the data structure.

Dean Michael Berris 68e74847bf [compiler-rt][XRay] Implement __xray_unpatch() and __xray_remove_handler()
Summary:
We also add one test (and the XRay testing infrastructure) to exercise
the patching and unpatching code. This uses the XRay API exported
through the headers as well, installing a custom log handler.

Depends on D23101 for the updated emitted code alignment for the
return/entry sleds.
