-- 389189dbb322df0d0468ab13edf7dc185dc63833 by Abseil Team <absl-team@google.com>: absl str_format.h can compile with -Wconversion and -Wsign-compare PiperOrigin-RevId: 420799960 -- 762e5adc429fc143756c42fe92fe8073c87c075f by Abseil Team <absl-team@google.com>: GetStackTraceWithContext: Fix min_dropped_frames when no frames are recorded Previously, if there were still frames to skip, they would be included in min_dropped_frames. PiperOrigin-RevId: 420766341 -- 7d4374b8eaa410f4f98ec03d6a8997dccadfb271 by Abseil Team <absl-team@google.com>: absl::flags compiles with -Wconversion and -Wsign-compare PiperOrigin-RevId: 420476807 -- 5f00f7805419d725fa1ff57b388e4c0750d1d6b0 by Derek Mauro <dmauro@google.com>: Internal change PiperOrigin-RevId: 420282152 -- bd5471fc34956acf3888bf90287b2aee4415c96d by Derek Mauro <dmauro@google.com>: Internal change PiperOrigin-RevId: 420282033 -- 61c78020804e4290e9b2fe151aeaf99b198716ee by Derek Mauro <dmauro@google.com>: Internal change PiperOrigin-RevId: 420281867 -- dbe3aad24b65ea11664401a307ea3d2f28e8a7b9 by Derek Mauro <dmauro@google.com>: Remove the incorrect test for the availability of [[nodiscard]] It should have been ABSL_HAVE_CPP_ATTRIBUTE(nodiscard) instead of ABSL_HAVE_ATTRIBUTE(nodiscard). As a result, some code is not compliant with [[nodiscard]], so we cannot simply correct the availability test. Recommend that C++17-only code use the standard [[nodiscard] directly.
