This is a follow-up to c8a016b99d97, following the post-landing discussion at https://chromium-review.googlesource.com/c/crashpad/crashpad/+/1393921/5#message-2058541d8c4505d20a990ab7734cd758e437a5f7 base::size, and std::size that will eventually replace it when C++17 is assured, does not allow the size of non-static data members to be taken in constant expression context. The remaining uses of ArraySize are in: minidump/minidump_exception_writer.cc (×1) minidump/minidump_system_info_writer.cc (×2, also uses base::size) snapshot/cpu_context.cc (×4, also uses base::size) util/misc/arraysize_test.cc (×10, of course) The first of these occurs when initializing a constexpr variable. All others are in expressions used with static_assert. Includes: Update mini_chromium to 737433ebade4d446643c6c07daae02a67e8deccao f701716d9546 Add Windows ARM64 build target to mini_chromium 87a95a3d6ac2 Remove the arraysize macro 1f7255ead1f7 Placate MSVC in areas of base::size usage 737433ebade4 Add cast Bug: chromium:837308 Change-Id: I6a5162654461b1bdd9b7b6864d0d71a734bcde19 Reviewed-on: https://chromium-review.googlesource.com/c/1396108 Commit-Queue: Mark Mentovai <mark@chromium.org> Reviewed-by: Mark Mentovai <mark@chromium.org>
