-- 23500704dd7c2642fad49f88c07ce41ebaab12e4 by Abseil Team <absl-team@google.com>: Change fetch_add() to store(1 + load()) As there is only one concurrent writer to the Info struct, we can avoid using the more expensive fetch_add() function. PiperOrigin-RevId: 329523785 -- 79e5018dba2e117ad89b76367165a604b3f24045 by Abseil Team <absl-team@google.com>: Record rehash count in hashtablez This will help identify which containers could benefit from a reserve call. PiperOrigin-RevId: 329510552 -- e327e54b805d67556f934fa7f7dc2d4e72fa066a by Abseil Team <absl-team@google.com>: Fix -Wsign-compare issues. These lines could theoretically have overflowed in cases of very large stack traces etc. Very unlikely, but this was causing warnings when built with -Wsign-compare, which we intend to enable with Chromium. In none of these three cases is it trivial to switch to a range-based for loop. PiperOrigin-RevId: 329415195 -- 08aca2fc75e8b3ad1201849987b64148fe48f283 by Xiaoyi Zhang <zhangxy@google.com>: Release absl::StatusOr. PiperOrigin-RevId: 329353348 -- bf4d2a7f8b089e2adf14d32b0e39de0a981005c3 by Xiaoyi Zhang <zhangxy@google.com>: Internal change PiperOrigin-RevId: 329337031 -- 42fa7d2fb993bbfc344954227cf1eeb801eca065 by Abseil Team <absl-team@google.com>: Internal change PiperOrigin-RevId: 329099807 GitOrigin-RevId: 23500704dd7c2642fad49f88c07ce41ebaab12e4 Change-Id: I6713e4ca3bb0ab2ced5e487827ae036ab8ac61f1
