* Prevent all CHECK functions from expanding macros for the error string.Gravatar Mike Kruskal2022-12-13
| | | | | | | | | This was likely an unintentional behavior change made a while ago while trying to reduce duplication. The new behavior will always include the unexpanded macro in the error string. For example, `CHECK_EQ(MACRO(x), MACRO(y))` will now output "MACRO(x) == MACRO(y)" if it fails. Before this change, CHECK and QCHECK were the only macros that had this behavior. Not using function-like macro aliases is a possible alternative here, but unfortunately that would flood the macro namespace downstream with CHECK* and break existing code.

* Eliminate AArch64-specific code paths from LowLevelHashGravatar Benjamin Barenblat2022-12-08
| | | | | | | | | | | | | | After internal investigation, it’s no longer clear that the alternative LowLevelHash mixer committed in a05366d851c5cb88065272f951e03955197e7c11 unequivocally improves performance on AArch64. It unnecessarily reduces performance on Apple Silicon and the AWS Graviton. It also lowers hash quality, which offsets much of the performance gain it provides on the Arm Neoverse N1 (see https://github.com/abseil/abseil-cpp/issues/1093). Switch back to the original mixer.

Also, move the infoz() accessor functions to be before the data members of CommonFields to comply with the style guide.
