+Abseil for Debian
+-----------------
+
+libabsl-dev installs a number of files to 'internal' directories. In general,
+your project should not directly include any files from these directories; they
+may change without warning. If you think you need something from one of those
+files, please report a bug with reportbug(1).

+Description: extensions to the C++ standard library
+ Abseil is an open-source collection of C++ library code designed to augment the
+ C++ standard library. The Abseil library code is collected from Google's C++
+ codebase and has been extensively tested and used in production. In some cases,
+ Abseil provides pieces missing from the C++ standard; in others, Abseil
+ provides alternatives to the standard for special needs.

+
+Abseil generates discrete distributions using Walker’s aliasing
+algorithm. This creates uniformly distributed buckets, each with a
+probability of sending traffic to a different bucket. Abseil represents
+a bucket as a pair
+
+ (probability of retaining traffic ×
+ alternate bucket if traffic is passed)
+
+and a distribution as a vector of such pairs. For example, {(0.3, 1),
+(1.0, 1)} represents a distribution with two buckets, the zeroth of
+which passes 70% of its traffic to bucket 1 and the first of which holds
+on to all its traffic.
+
+This representation is not unique: When a bucket retains traffic with
+probability 1, the alternate bucket is irrelevant. Continuing the
+example above, {(0.3, 1), (1.0, 0)} _also_ represents a two-bucket
+distribution where the zeroth bucket passes 70% of its traffic to the
+first and the first hangs on to all traffic. Exactly what representation
+Abseil generates for a given input is related to how much precision is
+used in intermediate floating-point operations, which is an
+architectural implementation detail. Remove sensitivity to that detail
+by not examining the alternate bucket when the retention probability is
+1.0.
+
+The author works at Google. Upstream applied this patch as Piper
+revision 372993410 and exported it to GitHub; the Applied-Upstream URL

+Subject: Disable SysinfoTest.NominalCPUFrequency on armel/armhf
+
+NominalCPUFrequency has different behavior on 32-bit and 64-bit ARM
+kernels. The Debian arm64 buildds assume they can build 32-bit ARM
+packages, but if they do, the NominalCPUFrequency test will fail.
+Disable the test when building for 32-bit ARM.

+Forwarded: yes

+
+This patch is a subset of the referenced commit, which originally also changed
+the mix function on arm64. The original message is as follows:
+
+ Alternative bit mixer for LowLevelHash on ARM
+
+ LowLevelHash's bit-mixer is inefficient on ARM because it calculates
+ a 128-bit product of two 64-bit numbers. On ARM, this requires a
+ sequence of two instructions with a high combined latency and poor
+ throughput. This change provides alternative bit-mixing code for ARM
+ that uses only 64-bit arithmetic (multiplication, xor, and
+ left-shifts) and speeds things up considerably.
+
+ The bit-mixing code for ARM was inspired by by Woothash[1] and
+ xxh3[1]. Once I landed on a sequence of operations that provided
+ good mixing, I used a test harness to search for the combination of
+ shift / rotate factors that provided the best mixing, as indicated
+ by SMHasher hash quality tests. The new mixing code passes 13 out of
+ 15 of the hash quality test suites in SMHasher, with the two
+ failures being in the noise range: e.g. 1 collision vs. zero
+ expected in a keyset of ~8m keys.

+
+Avoid using libstdc++'s implementation of std::hash<std::bitset> and
+std::hash<std::vector> on big endian platforms in the implementation
+of absl::Hash.
+
+This is a workaround for a buggy implementation that results in many

+Subject: Use absl::uint128 for AES random number generator
+Forwarded: yes
+Applied-Upstream: https://github.com/abseil/abseil-cpp/commit/b06e719ee985ecd63e0dffbc68499549216f817f
+
+Replace randen’s internal 128-bit integer struct, u64x2, with
+absl::uint128. This eliminates some code and improves support for
+big-endian platforms.
+
+The author works at Google. Upstream applied this patch as Piper
+revision 383475671 and exported it to GitHub; the Applied-Upstream URL
+above points to the exported commit.

+Configure Abseil for Debian.

+ - Set the SONAME appropriately.
+
+ - To minimize the possibility of future ABI breakage, treat absl::any,
+ absl::optional, absl::string_view, and absl::variant as their own types
+ (rather than aliases for the std:: versions), and compile everything in an
+ inline namespace.
+
+ - Enable upstream's hardened build mode.
+
+ - Disable Intel SSE2 on i386, since Debian supports some i386 processors

+ have it.
+
+ - Disable Intel SSSE3 entirely, since no i386 processor supports it and Debian

+The code

+ static_cast<int>(x * y)
+
+(for double x and y) performs a double multiplication into a temporary

+
+On 32-bit ARM, all functions are aligned to multiples of two bytes, and
+the lowest-order bit in a function’s address is ignored by the CPU when
+computing branch targets. That bit is still present in instructions and
+ELF symbol tables, though; it’s repurposed to indicate whether the
+function contains ARM or Thumb code. If the symbolizer doesn’t ignore
+that bit, it will believe Thumb functions have boundaries that are off
+by one byte, so instruct the symbolizer to null out the lowest-order bit
+after retrieving it from the symbol table.
