Summary:
Changes:
* Add initial msan stub support.
* Handle NetBSD specific pthread_setname_np(3).
* NetBSD supports __attribute__((tls_model("initial-exec"))),
define it in SANITIZER_TLS_INITIAL_EXEC_ATTRIBUTE.
* Add ReExec() specific bits for NetBSD.
* Simplify code and add syscall64 and syscall_ptr for !NetBSD.
* Correct bunch of syscall wrappers for NetBSD.
* Disable test/tsan/map32bit on NetBSD as not applicable.
* Port test/tsan/strerror_r to a POSIX-compliant OSes.
* Disable __libc_stack_end on NetBSD.
* Disable ReadNullSepFileToArray() on NetBSD.
* Define struct_ElfW_Phdr_sz, detected missing symbol by msan.
* Change type of __sanitizer_FILE from void to char. This helps
to reuse this type as an array. Long term it will be properly
implemented along with SANITIZER_HAS_STRUCT_FILE setting to 1.
* Add initial NetBSD support in lib/tsan/go/buildgo.sh.
* Correct referencing stdout and stderr in tsan_interceptors.cc
on NetBSD.
* Document NetBSD x86_64 specific virtual memory layout in
tsan_platform.h.
* Port tests/rtl/tsan_test_util_posix.cc to NetBSD.
* Enable NetBSD tests in test/msan/lit.cfg.
* Enable NetBSD tests in test/tsan/lit.cfg.

The map32bit.cc test uses the MMAP_32BIT flag which is supported only
on x86-64.

default.
Summary:
The triple is not the right thing to XFAIL on since LIT only sees the default
triple and not the effective triple chosen by any -target option in the RUN
directives. This discrepancy is shown in the table below:
Default Triple | Options | XFAIL | LIT's expected result | Desired expectation
=================+===================================+========+=======================+====================
mips-linux-gnu | -target mips-linux-gnu | | Pass | Pass
mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | | Pass | Pass
mips-linux-gnu | -target mips-linux-gnu | mips | Fail | Fail
mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips | Fail | Fail/Pass* (debatable**)
mips-linux-gnu | -target mips-linux-gnu | mips- | Fail | Fail

mips-linux-gnu | -target mips-linux-gnu | mips64 | Pass | Pass
mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips64 | Pass | Fail*

x64_64-linux-gnu | -target x86_64-linux-gnu | | Pass | Pass
x64_64-linux-gnu | -target i386-linux-gnu | i386 | Pass | Fail*
x64_64-linux-gnu | -target x86_64-linux-gnu | i386 | Pass | Pass
x64_64-linux-gnu | -target i386-linux-gnu | x86_64 | Fail | Pass
x64_64-linux-gnu | -target x86_64-linux-gnu | x86_64 | Fail | Fail*
* These all differ from LIT's current behaviour.
** People's expectations vary depending on whether they know that LIT does a
substring match on the default triple or think it's an exact match on an
architecture.
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:
Options | XFAIL | LIT's expected result
==================================+==================+======================
-target mips-linux-gnu | | Pass
-target mips64-linux-gnu -mabi=64 | | Pass
-target mips-linux-gnu | target-is-mips | Fail
-target mips64-linux-gnu -mabi=64 | target-is-mips | Pass
-target mips-linux-gnu | target-is-mips64 | Pass
-target mips64-linux-gnu -mabi=64 | target-is-mips64 | Fail
-target i386-linux-gnu | | Pass

-target x86_64-linux-gnu | target-is-i386 | Pass

This patch is by Simone Atzeni with portions by Adhemerval Zanella.
This contains the LLVM patches to enable the thread sanitizer for
PPC64, both big- and little-endian. Two different virtual memory
sizes are supported: Old kernels use a 44-bit address space, while
newer kernels require a 46-bit address space.
There are two companion patches that will be added shortly. There is
a Clang patch to actually turn on the use of the thread sanitizer for
PPC64. There is also a patch that I wrote to provide interceptor
support for setjmp/longjmp on PPC64.
Patch discussion at reviews.llvm.org/D12841.

Changing comments that have references to code.google.com to point to GitHub instead, because the current links are not redirected properly (they instead redirect to different issues, mostly ASan). NFC.

There's a few more lit tests that require features not available on OS X (MAP_32BIT, pthread_setname_np), let's mark them with "UNSUPPORTED: darwin".

This patch enabled TSAN for aarch64 with 39-bit VMA layout. As defined by
tsan_platform.h the layout used is:
0000 4000 00 - 0200 0000 00: main binary
2000 0000 00 - 4000 0000 00: shadow memory
4000 0000 00 - 5000 0000 00: metainfo
5000 0000 00 - 6000 0000 00: -
6000 0000 00 - 6200 0000 00: traces
6200 0000 00 - 7d00 0000 00: -
7d00 0000 00 - 7e00 0000 00: heap
7e00 0000 00 - 7fff ffff ff: modules and main thread stack
Which gives it about 8GB for main binary, 4GB for heap and 8GB for
modules and main thread stack.
Most of tests are passing, with the exception of:
* ignore_lib0, ignore_lib1, ignore_lib3 due a kernel limitation for
no support to make mmap page non-executable.
* longjmp tests due missing specialized assembly routines.
These tests are xfail for now.
The only tsan issue still showing is:
rtl/TsanRtlTest/Posix.ThreadLocalAccesses
Which still required further investigation. The test is disable for
aarch64 for now.

Even sleep(1) lead to episodical flakes on some machines.
Use an invisible by tsan barrier to enforce required execution order instead.
This makes the tests deterministic and faster.

Allow user memory in the first TB of address space.
This also enabled non-pie binaries and freebsd.
