adb22c8169 Switch from ALIGNAS() to alignas().
There is no longer a need to use this macro; compilers have no problem
with `alignas()` nowadays.

Subsequent CLs will remove the macro entirely once it's unused in both
Crashpad and Chromium.

dc489055ed Fix incorrect DCHECK in CET contexts
This DCHECK() was not correct. When dumping a process with CET
enabled the cetumsr and cetussp registers are not available in
the context obtained for the exception record. All contexts to be
written to a minidump must have the same context format so those
registers will be present for captured threads. It is therefore ok for
the context to expect extended xsave registers but for them to be
zero in some cases.

41f6ad560f Fix crashpad tests under UBSan
These are slightly frustrating. First, when a struct is packed, some of
its fields may be underaligned. This is fine for direct access
(foo.bar), but if one takes the address if the field, this creates an
unaligned pointer. Dereferencing that pointer is then UB. (I'm not sure
if creating that pointer is UB.)

Crashpad seemingly doesn't do this, but it uses EXPECT_EQ from GTest.
EXPECT_EQ seems to internally take pointers to its arguments. I'm
guessing it binds them by const reference. This then trips UBSan. To
avoid this, we can copy the value into a temporary before passing to
EXPECT_EQ.

Second, the test to divide by 0 to trigger SIGFPE is undefined behavior.
The compiler is not actually obligated to trip SIGFPE. UBSan prints one
of its errors instead. Instead, since this file is only built on POSIX
anyway, use GCC inline assembly to do the division. That one is
well-defined.

Finally, casting a string to uint32_t* is undefined both by alignment
and by strict aliasing (although Chromium doesn't enable the latter).
Instead, type-punning should be done with memcpy.

ARM64 supports storing pointer authentication codes in the upper bits of
a pointer. This mask can be used by LLDB to mimic ptrauth_strip and
strip the pointer authentication codes. To recover an address from
pointer with an authentication code, `AND` this mask with the pointer.

If the platform does not support pointer authentication, or the range of
valid addressees for a pointer was unaccessible, this field will be 0
and should be ignored.

339b125241 [minidump] Fix unaligned pointer in thread name list
https://crrev.com/c/3671775/ introduced a warning (and thus, a
compilation failure) on 32-bit ARM when taking the address of the RVA64
field MINIDUMP_THREAD_NAME::RvaOfThreadName:

minidump/minidump_thread_name_list_writer.cc:57:23: error: taking address of packed member 'RvaOfThreadName' of class or structure 'MINIDUMP_THREAD_NAME' may result in an unaligned pointer value [-Werror,-Waddress-of-packed-member]
  name_->RegisterRVA(&thread_name_.RvaOfThreadName);
                      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Indeed, MINIDUMP_THREAD_NAME's RvaOfThreadName field is not aligned,
so the technique used in MinidumpWritable::Register*() of passing in a
rawptr to an arbitrary struct field which is later dereferenced cannot
be used for this field.

This CL replaces the use of MinidumpWritable::Register*() with
overriding MinidumpThreadNameWriter::WillWriteAtOffsetImpl() to
directly calculate and assign thread_name_.RvaOfThreadName.

9e0051aba6 Write compacted xsave contexts in minidumps
Adds new structures and offsets for minidump extended contexts. This
information will be captured from threads in a later CL so this CL
does not yet write different dumps, except in testing.

Minidump format for extended compacted contexts has been determined by
experiment. Offsets for where to write various parts of the context
are hardcoded to 0x550 as this matches values seen in Windows. Offsets
for misc_info_5 match those seen in working minidumps that can be opened
in windbg. Our hope is that while these could change in future, CPU
and OS vendors are unlikely to change them.

See doc[0] for a discussion of these fields and offsets in the minidump.

See "MANAGING STATE USING THE XSAVE FEATURE SET" Chapter 13 in the
Intel SDM[1]. Many of the offsets and sizes of the extended features
are provided by cpu specific values. We can access these in Windows
using the SDK, and transfer these to the saved extended context
which in turn is understandable by windbg.

Further information is available from AMD Ch. 18 "Shadow Stacks"[2].

1aa478d161 Remove DISALLOW_* macros in crashpad
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
ignore_result, which is the only other thing defined in base/macros.h.

d5d78c1469 [third_party] Make mini_chromium relocatable
This will accommodate moving third_party/mini_chromium around.
The default location is unchanged for now.

There are GN variables that may need to be updated when Fuchsia's source
re-organizes its layout:

* mini_chromium_source_parent : this contains a BUILD.gn with groups and
encloses the mini_chromium_source_root.  This is controlled by the
structure of the project that depends on this project.

* _mini_chromium_source_root : this is what is normally checked out from
git, the upstream source directory

* mini_chromium_import_root : points inside source_root to make GN files
accessible.

This first step breaks out case logic for "if (crashpad_is_in_fuchsia)"
even if the value is unchanged for now.  This will faciliate a smaller
change when Fuchsia re-structures third_party sources.

8804387c75 Fix -Wc++11-narrowing in crashpad.
timeval's first member's type is __kernel_old_time_t on at least
Windows; this is a 32-bit type as opposed to time_t, which is a 64-bit
type.  As a result, casting directly to time_t results in a truncation,
triggering the warning.

It's not possible to cast directly to __kernel_old_time_t, since that
type is not exposed here.  Instead, cast to the underlying type, long,
which should work correctly on all platforms.

This has Year 2038 problems (which is why time_t is switching to
64-bit), which I suspect would be best fixed by a larger change like
moving away from using timeval anywhere (?).  I'm not really certain
what all would be involved in trying to make this whole pipeline
Y2038-safe, so I haven't attempted to tackle this.

This is no longer sufficient to identify OS versions accurately in macOS
11. A new MacOSVersionNumber function reports the full OS version as

MacOSXVersion is also renamed to MacOSVersionComponents for

bdf9471324 mac: Switch from <AvailabilityMacros.h> to <Availability.h>
The macOS 11.0 SDK, as of Xcode 12b6 12A8189n, has not updated
<AvailabilityMacros.h> with a MAC_OS_X_VERSION_11_0 or
MAC_OS_X_VERSION_10_16 constant. However, the <Availability.h> interface
has been updated to provide both __MAC_11_0 and __MAC_10_16.
<AvailabilityMacros.h>’s MAC_OS_X_VERSION_MAX_ALLOWED, which is supposed
to identify the SDK version, is broken in the 11.0 SDK in that whenever
the deployment target is set to 10.15 or earlier, the SDK will be
mis-identified through this interface as 10.15. When using the
<Availability.h> equivalent, __MAC_OS_X_VERSION_MAX_ALLOWED, the 11.0
SDK is identified as 10.16 (arguably it should be internally versioned
as 11.0, but at least this interface allows it to be detected
unambiguously.) It’s clear that the <AvailabilityMacros.h> interface
provides no meaningful support for the macOS 11.0 SDK at all, but
<Availability.h> does.

<Availability.h> was introduced in the Mac OS X 10.5 SDK, so there is no
relevant SDK version compatibility problem with this interface.

Key differences between these interfaces for the purposes used by
Crashpad:
 - <AvailabilityMacros.h> → <Availability.h>
 - MAC_OS_X_VERSION_MIN_REQUIRED (DT) → __MAC_OS_X_VERSION_MIN_REQUIRED
 - MAC_OS_X_VERSION_MAX_ALLOWED (SDK) → __MAC_OS_X_VERSION_MAX_ALLOWED
 - MAC_OS_X_VERSION_x_y → __MAC_x_y
 - <Availability.h> __MAC_OS_X_VERSION_* SDK/DT macros are only
   available when targeting macOS, while <AvailabilityMacros.h>
   MAC_OS_X_VERSION_* SDK/DT macros are available on all Apple platforms,
   which may be a source of confusion. (<Availability.h> __MAC_* macros
   do remain available on all Apple platforms.)

This change was made mostly mechanically by:

sed -i '' -Ee 's/<AvailabilityMacros.h>/<Availability.h>/g' \
    $(git grep -E -l '<AvailabilityMacros.h>' |
          grep -v AvailabilityMacros.h)

sed -i '' -Ee 's/(MAC_OS_X_VERSION_(MIN_REQUIRED|MAX_ALLOWED))/__\1/g' \
    $(git grep -E -l 'MAC_OS_X_VERSION_(MIN_REQUIRED|MAX_ALLOWED)' |
          grep -v AvailabilityMacros.h)

sed -i '' -Ee 's/(MAC_OS_X_VERSION_(10_[0-9]+))/__MAC_\2/g' \
    $(git grep -E -l 'MAC_OS_X_VERSION_(10_[0-9]+)' |
          grep -v AvailabilityMacros.h)

828095ac32 Clear the gn sources_assignment_filter when building in Chromium
Chromium relies on a global gn sources assignment filter, even though
it’s kind of discouraged. Crashpad doesn’t use this, instead selecting
which files to build entirely with the logic in its .gn files. In some
cases, Chromium’s filters prevent _linux files from building on Android,
and _mac files from building on iOS, even though Crashpad’s build has
explicitly requested these inclusions. To overcome this problem,
clear the gn sources_assignment_filter in all of Crashpad’s own .gn
files when building in Chromium.

161bfed35a Remove/replace unnecessary includes of logging.h
If the file just needs the CHECK/CHECK_OP/NOTREACHED
macros, use the appropriate header for that instead.
Or if logging.h is not needed at all, remove it.

This is both a nice cleanup (logging.h is a big header,
and including it unnecessarily has compile-time costs),
and part of the final step towards making logging.h no
longer include check.h and the others.

a45eea40fc Update gtest to e3f0319d89f4cbf32993de595d984183b1a9fc57
I’m most interested in picking up 1b3eb6ef3462, “Explicitly define copy
constructors used in googletest tests.”

This also reorganizes files and rewrites text to refer to this project
as Google Test and googletest (and Google Mock and googlemock), as it
prefers to be known. Some filenames are left at gtest_* following the
precedent set by gtest itself. For example, #include "gtest/gtest.h" is
still used, so #include "test/gtest_death.h" is retained too.
gtest_all_test OutputFileHelpersTest.GetCurrentExecutableName hard-codes
the expected executable name as gtest_all_test among other options that
do not include googletest_all_test, so test executables retain their
names as well.

194e23910c Change for loops to use const references where they did not previously
From cl/304219049:

Optimize C++11 range-based for loops where the variable is copied in
each iteration but it would suffice to obtain it by const reference.
This is only applied to loop variables of types that are expensive to
copy which means they are not trivially copyable or have a non-trivial
copy constructor or destructor.

To ensure that it is safe to replace the copy with a const reference,
the following heuristic is employed:
 - The loop variable is const qualified.
 - The loop variable is not const, but only const methods or operators
   are invoked on it, or it is used as const reference or value argument
   in constructors or function calls.
