(-O1 is fine). This is a new regression introduced in GCC9.
For everyone's safety, extend -O0 hack to dwarf2{expr,loc}.c for
all arm variants with GCC >= 8.
Summary of changes in tzdata2020b (2020-10-06 18:35:04 -0700):
Revised predictions for Morocco's changes starting in 2023.
Canada's Yukon changes to -07 on 2020-11-01, not 2020-03-08.
Macquarie Island has stayed in sync with Tasmania since 2011.
Casey, Antarctica is at +08 in winter and +11 in summer.
GCC 9.3 seems to be able to compile rtree.c with -O2:
- No new regressions in ATF.
- System survives over a night, at least, under heavy loads.
On the other hand, unfortunately, GCC 9.3 still miscompiles tcache.c
with -O2 or -O1. For example, even ``gcc -g hello.c'' fails with ICE
if tcache.c is compiled with -O[12] in libc.

Subject: [PATCH] Preinitialize the sockaddr_un variable to zero
Don't pass random sun_len for the BSD's,
zero the whole structure as recommended for portability.
Reported by Coverity.
gdbsupport/ChangeLog:
* agent.cc (gdb_connect_sync_socket): Preinitialize addr with zeros.
* dhcpcd: Backticks have been removed from quoting filenames
* dhcpcd: Only manipulate stdin, stdout and stderr if they are valid
* duid: Adjust option so the type can be specified
* logerr: Don't leak logfile fd to scripts
* privsep: Run the launcher process in the sandbox
* BSD: Use `ifi_link_state` as the single source of truth about carrier
* BSD: Ignore vether(4) devices by default
fonts included as part of X11 that are also included as scalable fonts
as part of macOS.
Many websites will attempt to select these fonts, which results in
very strange, poor quality rendering.
This should keep legacy X11 applications that want the old "Helvetica"
and "Times" fonts working, but prevent them from being selected by
applications that want scalable fonts.
It should not prevent "Helvetica" or "Times" from being selected
if the user installs a scalable version.
aka "the memcmp bug", from a patch for gcc-10 in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95189
Tested on x86_64 by running a full build, install and running it.
Testing that the problem has been fixed with one of the unit tests provided.

Subject: [PATCH] [compiler-rt] [netbsd] Improve the portability of
ThreadSelfTlsTcb
Use __lwp_gettcb_fast() and __lwp_getprivate_fast(), as _lwp_getprivate()
can be a biased pointer and invalid for use in this function on all CPUs.
- Bug fixes to gmp_snprintf, conversion to double, mpz_powm,
and mpf_set_str.
- New functions for factorial, primorial, fibonacci, mpz_2fac_ui,
and mpz_mfac_uiui.
- MIPS r6 cores are now supported.
- Various speeds ups.
Changed __float128 to the type _Float128 specified in ISO/IEC TS 18661.
__float128 is used as a fallback if _Float128 is not supported.
New function mpfr_get_str_ndigits about conversion to a string of digits.
New function mpfr_dot for the dot product (incomplete, experimental).
New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available
only when MPFR has been built with decimal float support).
New function mpfr_cmpabs_ui.
New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
The mpfr_out_str function now accepts bases from -2 to -36, in order to
follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
assertion failure, as with other invalid bases).
Shared caches: cleanup; really detect lock failures (abort in this case).
Improved mpfr_add and mpfr_sub when all operands have a precision
equal to twice the number of bits per word, e.g., 128 bits on a 64-bit
platform.
Optimized the tuning parameters for various architectures.
0's and svr4_exec_displacement read phdrs_target successfully, and we
end up in the rabbit-hole of 0 displacement for pie binaries and then we
can't load our shared libaries from the core file.
this is an optimization that primarily benefits linux/glibc -
most other systems have this disabled. in netbsd we've tried to
patch around it to make things work, but there still appears to be
some edge cases where libGL mysteriously crashes.

Changes:
- define fileno_unlocked() for NetBSD
- use defined __sanitizer_FILE for NetBSD
- handle symbol indirection for vfork and nanosleep
- delete sem_* API, currently moved to common code with sanitizers
- undef SANITIZER_INTERCEPT_PTHREAD_SIGMASK to fix build
- remove locally introduced SANITIZER_NETBSD
With these changes, TSan for GCC builds.
Use the 2020-09-10 snapshot to replace two-years-old GCC9 copy of
interceptors.
With this change, ASan works with the locally patched GCC tree (as there
were IOCTL operations not properly defined).
- alpha is running and no regression in ATF (tests in lib/libc/sys are
skipped due to port-alpha/55652).
- m68000 is successfully built and running at a same level as before.
- m68k (amiga, mac68k, sun3) is running and no regression in a tiny
subset of ATF (kernel, lib/libc/{gen,sys}).
- macppc (oea) and evbppc (booke, ibm4xx) are running and no regression
in ATF.

Add NetBSD LSan support
Summary:
Combine few relatively small changes into one:
- implement internal_ptrace() and internal_clone() for NetBSD
- add support for stoptheworld based on the ptrace(2) API
- define COMPILER_RT_HAS_LSAN for NetBSD
- enable tests for NetBSD/amd64
Inspired by the original implementation by Christos Zoulas in netbsd/src for GCC.
The implementation is in theory CPU independent through well defined macros
across all NetBSD ports, however only the x86_64 version was tested.

Stop tracking atexit/__cxa_atexit/pthread_atfork allocations in LSan/NetBSD
Summary:
The atexit(3) and __cxa_atexit() calls allocate internally memory and free on exit,
after executing all callback. This causes false positives as DoLeakCheck() is called
from the atexit handler. In the LSan/ASan tests there are strict checks triggering
false positives here.
Intercept all atexit(3) and __cxa_atexit() calls and disable LSan when calling the
real functions.
Stop tracing allocations in pthread_atfork(3) funtions, as there are performed
internal allocations that are not freed for the time of running StopTheWorld()
code. This avoids false-positives.
The same changes have to be replicated in the ASan and LSan runtime.
Non-NetBSD OSs are not tested and this code is restricted to NetBSD only.

Add __lsan::ScopedInterceptorDisabler for strerror(3)
Summary:
strerror(3) on NetBSD uses internally TSD with a destructor that is never
fired for exit(3). It's correctly called for pthread_exit(3) scenarios.
This is a case when a leak on exit(3) is expected, unavoidable and harmless.

into '_' to meet sh variable name rules) into a shell string processing
loop.
On my test system, this reduces the total elapsed time for the bin/sh ATF
tests from about 109 secs to about 102 (user cpu from 24.5 to 21, sys cpu
from 34 to 30) and the usr.bin/make tests elapsed time from 42.5 to 40
secs (user from a bit over 15 to a bit over 13, and sys from 16+ to 13+).
(Recorded on an AMD64 domU).
These probably exaggerate the effect, as there are a bunch of quite small
tests, which means the ATF overhead (which this change affects) is a greater
proportion of the total test time than for some other tests where most of
the time is spent actually testing.
But I am fairly confident that there will be at least some improvement.
This could be further improved by removing the cmdsub invocation method,
and instead passing the name of a variable containing the string to
normalise (with the result returned in that same var) - but that would
mean altering all the callers as well. Some other time maybe.
Cherry-pick and adapt:

[compiler-rt] [netbsd] Switch to syscall for ThreadSelfTlsTcb()
This change avoids using internal, namespaced per-CPU calls that
are not a stable interface to read the TSL base value.
- most builds are working
- arm64, amd64, sparc, evbmips64-eb, and armv7hf-el are known to be
stable and work
- mips64-el needs new binutils, in testing
- vax, sh3*, riscv64 and mipse[lb] builds are broken in various ways
