This can be used by 12Chromium, subject to the guidance at 13https://chromium.googlesource.com/chromium/src/+/main/styleguide/c++/c++-features.md; 14it can be used without restriction by Chromium's dependencies, except that 15objects compiled into Chromium itself cannot use anything relying on 16absl::base_internal::FastTypeId (see https://crbug.com/1096380). 17 18How to update Abseil: 19 201. From your source root run third_party/abseil-cpp/roll_abseil.py to download the code from the Abseil git repository and apply chromium specific patches. 21 222. Update BUILD.gn files to match changes in BUILD.bazel 23 24If there is a new test, add dependcy on it from absl_tests in the 25third_party/abseil-cpp/BUILD.gn target 26 273. From your source root run third_party/abseil-cpp/generate_def_files.py to 28 regenerate Windows symbol definition files. 29 304. If abseil adds new features, update styleguide/c++/c++-features.md and add headers for that feature into exclude list in root DEPS 31 32Local Modifications: 33 34* absl/copts.bzl has been translated to //third_party/absl-cpp/BUILD.gn. Both 35 files contain lists of compiler flags in order to reduce duplication. 36 37* All the BUILD.bazel files have been translated to BUILD.gn files. 38 39* Patches from //third_party/abseil-cpp/patches have been applied. 40 41* Increment this number to silence presubmits about modifying files in 42 third_party when regenerating absl .def files: 2 43
