In this PR I propose to refresh the included headers in hotspot `precompiled.hpp`. The current set of precompiled headers was refreshed in 2018, 7 years ago. I repeated the same operations and measurements after refreshing the set of precompiled headers according to the current usage frequency.
These are the results I observed. Depending on the platform, the improvement is between 10 and 20% in terms of total work (user+sys). The results are in seconds. linux-x64 GCC master real 81.39 user 3352.15 sys 287.49 JDK-8365053 real 81.94 user 3030.24 sys 295.82 linux-x64 Clang master real 43.44 user 2082.93 sys 130.70 JDK-8365053 real 38.44 user 1723.80 sys 117.68 linux-aarch64 GCC master real 1188.08 user 2015.22 sys 175.53 JDK-8365053 real 1019.85 user 1667.45 sys 171.86 ------------- Commit messages: - refresh Changes: https://git.openjdk.org/jdk/pull/26681/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=26681&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8365053 Stats: 41 lines in 1 file changed: 1 ins; 28 del; 12 mod Patch: https://git.openjdk.org/jdk/pull/26681.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/26681/head:pull/26681 PR: https://git.openjdk.org/jdk/pull/26681
