Summary: Use isb instead of yield on arm64
Key: IMPALA-12122
URL: https://issues.apache.org/jira/browse/IMPALA-12122
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 4.2.0
Reporter: Sebastian Pop
Chromium switched the implementation of atomicops.h and family to use the C++11
atomics library in this change:
[https://github.com/chromium/chromium/commit/57a4e4a50c673c25e9cdaab53e32f6e53aa0b574]
It allowed for a large simplification later on where most of the
platform-specific logic and assembly could be removed. This seems easier to
maintain than the current code.
