3996b01f0c3eb60f72825b154dce8019b6215f1d by Derek Mauro <dmauro@google.com>:

Add GCC 4.9 test script. This will become our new minumum version and
GCC 4.8 will be removed soon.

[Trivial] tweak flat_hash_map.h doc comment

The comment is probably right both ways, but the lack of an "if" here seemed jarring to me.

16bc03b9b30fbf08d7dc61025fa8ec4b57077be8 by Abseil Team <absl-team@google.com>:

Fix symbolization for elf files whose SYMTAB section is stripped, but have a DYNSYM section.

Previously, if we did not find a SYMTAB section, we would bail out of symbolization early, rather than checking the DYNSYM section.

4c60ee329b1eeb0b0d10c4f76f282e5fbae2c5b2 by Derek Mauro <dmauro@google.com>:

18e1ba970d33f122026803d8ca90035b9088949d by Eric Fiselier <ericwf@google.com>:

Disable variant tests that break with P0608R3

9b7424cac66f5407f0ed74ed288bf3099a4fa330 by CJ Johnson <johnsoncj@google.com>:

Updates the implementation of InlinedVector::insert(...) to be exception safe and adds an exception safety tests for insert(...)

39c04f3621491eaff9e2eda619718d5b5f20fbd9 by Abseil Team <absl-team@google.com>:

Use a typedef to allow building with NVCC

Without this change NVCC fails to compile compressed_tuple.h.  NVCC is relevant
because TensorFlow uses NVCC on Ubuntu and inclues abseil.

054aafcebf595077054164f1da3703124ab209b4 by Abseil Team <absl-team@google.com>:

Updates the ScopedAllocatorWorks test for InlinedVector to not rely on the byte count allocated by the standard library

In doing so, removes LegacyNextCapacityFrom(...) impl function from InlinedVector

Also applies clang-format to the test file

Enhance compatibility of abseil's strings package with nvcc.

efc5b9c221ee31e15d10b35d31c8f3ae6eddaa8c by Abseil Team <absl-team@google.com>:

Follow CCTZ's lead and allow GetWeekday() and GetYearDay() to be
called with any civil-time type.  A CivilSecond, for example, has
a weekday just as much as a CivilDay does.

Increase the timeout of randen_engine_test.
It seems to timeout under TSAN often enough to justify the increase.
