-- 2c5c118f0615ba90e48ee2f18eccc9f511740f6d by Samuel Benzaquen <sbenza@google.com>: Rename internal macros to follow the convention in absl. PiperOrigin-RevId: 299906738 -- 92d84a707c7ebc4ec19bdd92d5765d1b6d218c1e by Derek Mauro <dmauro@google.com>: Import GitHub #629: Skip the .exe suffix in the helpshort filter on Windows PiperOrigin-RevId: 299892396 -- 2a6910d4be6c67a8376628764121b528ff53504d by Abseil Team <absl-team@google.com>: Use unsigned int128 intrinsic when available. It generates better branchless code. PiperOrigin-RevId: 299848585 -- 110c16cf0a739e1df5028fb6fbd03ef5dde1d278 by Derek Mauro <dmauro@google.com>: Import GitHub #594: Avoid reading the registry for Windows UWP apps PiperOrigin-RevId: 299821671 -- d8397d367e88163e5e8a47f379c716352dc91d03 by Greg Falcon <gfalcon@google.com>: Add absl::Hash support for Cord. The hash function is heterogeneous with other string types: a Cord and a string with the same byte sequence will hash to the same value. SwissTable types know about Cord, and will allow heterogeneous lookup (e.g., you can pass a Cord to flat_hash_map<string, T>::find(), and vice versa.) Add a missing dependency to the cmake Cord target. PiperOrigin-RevId: 299443713 GitOrigin-RevId: 2c5c118f0615ba90e48ee2f18eccc9f511740f6d Change-Id: I7b087c7984b0cb52c4b337d49266c467b98ebdf9
