* | StrFormat() simplification: Treat %v unconditionally as %d when formatting ↵Gravatar Greg Falcon2023-06-09
| | | | | | | | | | | | | | | | | | integers. This is a simplification but not a behavior change; we used to choose %u for unsigned ints, but %u and %d generate the same output for these types. PiperOrigin-RevId: 539104599 Change-Id: I9d7ff561b969a6287889f95063636d6b77a4a78b

* Migrate most RAW_LOGs and RAW_CHECKs in tests to regular LOG and CHECK.Gravatar Andy Getzendanner2023-05-23
| | | | | | | | | | | The non-RAW_ versions provide better output but weren't available when most of these tests were written. There are just a couple spots where RAW_ is actually needed, e.g. signal handlers and malloc hooks. Also fix a couple warnings in layout_test.cc newly surfaced because the optimizer understands CHECK_XX differently than INTERNAL_CHECK.

* Fix C++17 constexpr storage deprecation warningsGravatar Derek Mauro2022-06-09
| | | | | | | | | | | | | | | | | | | This change introduces the symbol ABSL_INTERNAL_NEED_REDUNDANT_CONSTEXPR_DECL to guard redundant declarations of static constexpr data members that are needed prior to C++17. This change also introduces the symbol ABSL_INTERNAL_CPLUSPLUS_LANG, which is supposed to be set to the same value as __cplusplus, except it uses _MSVC_LANG on MSVC so that the value is correct on MSVC.

This benchmark has significantly different possible behaviors that can result in misleading metrics. Specifically, we can have a case where we are deallocating the last node in the b-tree in the erase and then allocating a new node in the insert call repeatedly, whereas normally, we end up just inserting/erasing a value from the last node. Also, the name of the benchmark is misleading because it involves an erase and an insert, but the name only mentions the insert.

We’ve already special-cased double-double arithmetic in a number of tests, but compiler bugs [1, 2, 3] have now triggered both false positives and false negatives, which suggests testing with double doubles is unlikely to yield useful signal.
