In current GHA, `hotspot_compiler` testing takes a long time, and often takes the longest. On MacOS and Windows it routinely takes 60..80 minutes, while other test groups run in 30..40 minutes. This often drags the total wall clock time to run the GHA up. Fortunately, there are already several parts in `hotspot_compiler` test group, which we might just run separately: https://github.com/openjdk/jdk/blob/dc256fbc6490f8163adb286dbb7380c10e5e1e06/test/hotspot/jtreg/TEST.groups#L142-L146
There is a bit of awkwardness about `not_xcomp` subgroup, which does not have lots of tests. Instead of doing another short job, I think we can just meld it into the quickest "part 2". # Before linux-x64 / test (hs/tier1 compiler) 38m 27s windows-x64 / test (hs/tier1 compiler): 1h 17m 30s macos-x64 / test (hs/tier1 compiler): 1h 2m 53s # After linux-x64 / test (hs/tier1 compiler part 1): 11m 38s linux-x64 / test (hs/tier1 compiler part 2): 9m 34s linux-x64 / test (hs/tier1 compiler part 3): 21m 40s windows-x64 / test (hs/tier1 compiler part 1): 24m 19s windows-x64 / test (hs/tier1 compiler part 2): 18m 54s windows-x64 / test (hs/tier1 compiler part 3): 43m 32s macos-x64 / test (hs/tier1 compiler part 1): 26m 44s macos-x64 / test (hs/tier1 compiler part 2): 20m 40s macos-x64 / test (hs/tier1 compiler part 3): 42m 10s Additional testing: - [x] GHA (current run is in progress, but I had clean runs before) ------------- Commit messages: - Job name is actually wrong - Move xcomp to part 2 - Work Changes: https://git.openjdk.org/jdk/pull/16860/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=16860&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8320921 Stats: 13 lines in 1 file changed: 10 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/16860.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/16860/head:pull/16860 PR: https://git.openjdk.org/jdk/pull/16860
