Several test cases that used to fail on both power LE and BE
now run correctly on LE.

Bill Schmidt 2979162732 [PPC64, TSAN] LLVM basic enablement of thread sanitizer for PPC64 (BE and LE)
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.

Kuba Brecka 6c9122ffba [tsan] Change comments referencing code.google.com to point to GitHub instead. NFC.
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.

Kuba Brecka 77ff411247 [tsan] Fix signals and setjmp/longjmp on OS X
1) There's a few wrongly defined things in tsan_interceptors.cc,
2) a typo in tsan_rtl_amd64.S which calls setjmp instead of sigsetjmp in the interceptor, and
3) on OS X, accessing an mprotected page results in a SIGBUS (and not SIGSEGV).

Adhemerval Zanella 2f7f5e3535 [compiler-rt] [tsan] Enable intercept setjmp/longjmp for AArch64
This patch adds assembly routines to enable setjmp/longjmp for aarch64
on linux.  It fixes:

 * test/tsan/longjmp2.cc
 * test/tsan/longjmp3.cc
 * test/tsan/longjmp4.cc
 * test/tsan/signal_longjmp.cc

I also checked with perlbench from specpu2006 (it fails to run
with missing setjmp/longjmp intrumentation).

Adhemerval Zanella d7984710ae [tsan] Enable tsan for aarch64
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.

Dmitry Vyukov c0ae07e98c tsan: fix signal_longjmp test in debug mode
In debug mode tsan checks that user accesses
access user memory. NULL is not user memory.
So the test fails. Allocate real inaccessible
memory for the test.
