Hi,
After SAP discontinued the support of linuxppc64 and aixppc64
of OpenJDK 8 I want to share how we ran the
hotspot jtreg tests, and especially which tests we excluded.
Most of the test excludes could be fixed by downporting
test changes.
Also, issues might be fixed after we excluded them, I did not
check this.
We build with only mandatory configure settings, except for the following:
linuxppc64: --with-extra-cflags=-Wno-strict-aliasing
aix: --with-native-debug-symbols=internal
We run jtreg with the following settings:
-Djava.awt.headless=true
-k:(!headful)&(!ignore)&(!stress)&(!intermittent)
We excluded the following tests:
First, tests that fail on all platforms we tested:
# Testbug
# This test copied or moved the root directory / to some subdirectory, filling up the disc
compiler/ciReplay/TestSA.sh generic-all
compiler/ciReplay/TestVM_no_comp_level.sh generic-all
compiler/ciReplay/TestVM.sh generic-all
# Fails in 8 until 8044416 will be fixed or
# the test exclusion change 8044540 will be downported from jdk9
serviceability/sa/jmap-hashcode/Test8028623.java generic-all
# Fixed in 11 by 8195621: JTReg failure: gc/g1/TestLargePageUseForAuxMemory.java
gc/g1/TestLargePageUseForAuxMemory.java generic-all
Further, tests we see failing on ppc but not on x86_64.
