=== Progress ===
* Get TSAN building for Aarch64 on 42-bit VMA systems. (4/10) (-pie mode only)

Expected Passes : 253
Expected Failures : 2
Unsupported Tests : 1
Unexpected Failures: 13

The failures are categorized into three types.
(1) setjmp and longjmp implementation in assembly needs to written for Aarch64 .

ThreadSanitizer :: longjmp.cc
ThreadSanitizer :: longjmp2.cc
ThreadSanitizer :: longjmp3.cc
ThreadSanitizer :: longjmp4.cc
ThreadSanitizer :: signal_longjmp.cc

(2) FATAL: ThreadSanitizer: failed to intercept pthread_cond_init. I
need to debug and see why this happens.
ThreadSanitizer :: bench_mutex.cc
ThreadSanitizer :: cond.c
ThreadSanitizer :: cond_cancel.c
ThreadSanitizer :: cond_race.cc
ThreadSanitizer :: cond_version.c
ThreadSanitizer-Unit :: rtl/TsanRtlTest/Posix.CondBasic

(3) TLS descriptions ThreadDescriptorSize (), GetTls () and ThreadSelf
() defintions are needed for aarch64.
tls_race.cc
tls_race2.cc

Some ptrace defintions are needed PTRACE_GETREGS, PTRACE_SETREGS
PTRACE_GETFPREGS, PTRACE_SETFPREGS for sanitizer, but they are not
implemented for Aarch64. I am planning to switch off that code in
TSAN.

* ASAN/TSAN documentation. ASAN documentation complete. TSAN in progress. (4/10)


* Emails, meetings. (2/10)
* Linaro 1-1 with christophe, Ryan.
* AMD meetings/event, 1-1 with AMD manager, status meeting.
* GCC mailing list.

===Plan ===
Complete TSAN documentation.
Analyze remaining failures for TSAN.
Push LLVM tree to git.linaro.org for handover.
