Previously we would rely on implicit re-raising to deliver signals to
the underlying handler on POSIX systems if the signal is detected as
being re-raisable via WillSignalReraiseAutonomously(). This detection
mechanism is imperfect, as it will misclassify signals delivered as
a result of kill(2) when passing a signal number usually used for
synchronous signals, but now also asynchronous MTE tag check faults,
which are delivered as SIGSEGV signals on Linux. As a result, these
signals would not be re-raised and therefore would be discarded.
Although we could, for example, teach WillSignalReraiseAutonomously()
about MTE faults, the signal would still be re-raised via raise(3)
and therefore we would lose the information in siginfo.
We can avoid discarding these signals on Linux while at the
same time preserving the siginfo by making use of the syscall
rt_tgsigqueueinfo(2) which delivers a signal together with a
user-provided siginfo. The problem still exists on non-Linux POSIX
systems because this syscall is Linux-specific.
With kernel versions prior to 3.9, the kernel will reject the
rt_tgsigqueueinfo() syscall with EPERM. If that happens, follow
the non-Linux code path.

The way that division operations behave have changed between Armv7
and Armv8. On the later one, divisions by zero will *not* yield an
exception of any kind (for both a 32bit and 64bit app), for hardware
integer divide operation.
On Arm processors exceptions may also be a factor of:
- if the hardware implementation supports it.
- if the kernel has set the proper internal state registers/flags.
- C library implementations (e.g. libgcc x clang_rt).
Aside that, a division by zero is within the realm of UD (Undefined
Behavior) in C/C++.
Since there are two categories of tests (explicit raise x caused by
instructions), it just makes sense to disable the second for Arm
since there is no reliable way to cause a SIGFPE without an explicit
raise() POSIX call.
For x86, we keep the previous implementation idea but streamlined
the code by deploying 'volatile' to ensure that the compiler
won't optimize away the result of the division (i.e no need
to call stat() and fstat()).

This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.
#include "base/macros.h" is removed from files that don't use

base::size, and std::size that will eventually replace it when C++17 is
assured, does not allow the size of non-static data members to be taken
in constant expression context. The remaining uses of ArraySize are in:
minidump/minidump_exception_writer.cc (×1)
minidump/minidump_system_info_writer.cc (×2, also uses base::size)
snapshot/cpu_context.cc (×4, also uses base::size)
util/misc/arraysize_test.cc (×10, of course)
The first of these occurs when initializing a constexpr variable. All
others are in expressions used with static_assert.

gtest used to require (expected, actual) ordering for arguments to
EXPECT_EQ and ASSERT_EQ, and in failed test assertions would identify
each side as “expected” or “actual.” Tests in Crashpad adhered to this
traditional ordering. After a gtest change in February 2016, it is now
agnostic with respect to the order of these arguments.
This change mechanically updates all uses of these macros to (actual,
expected) by reversing them. This provides consistency with our use of
the logging CHECK_EQ and DCHECK_EQ macros, and makes for better
readability by ordinary native speakers. The rough (but working!)
conversion tool is
https://chromium-review.googlesource.com/c/466727/1/rewrite_expectassert_eq.py,
and “git cl format” cleaned up its output.
EXPECT_NE and ASSERT_NE never had a preferred ordering. gtest never made
a judgment that one side or the other needed to provide an “unexpected”
value. Consequently, some code used (unexpected, actual) while other
code used (actual, unexpected). For consistency with the new EXPECT_EQ
and ASSERT_EQ usage, as well as consistency with CHECK_NE and DCHECK_NE,
this change also updates these use sites to (actual, unexpected) where
one side can be called “unexpected” as, for example, std::string::npos
can be. Unfortunately, this portion was a manual conversion.
