Thomas/Volker, et al
Thanks to your assistance, I've been SUCCESSFUL in building a native =
ppc64 jdk8 on FreeBSD.
To validate the build, I made a couple of regression test runs with =
results similar to the Zero VM build in the same environment. Although, =
not all tests completed successfully (some of the failed test were due =
to missing test files in the distribution). The regression test stats =
file is attached.=20
I've created a set of initial patches for the code and several patches =
for the build system. However, there's one build system issue that I've =
not yet resolved. At the end of the Hotspot build, it errors because it =
cannot find jvmti.hmtl, jvmti.h, libjsig.so and libjvm.so. The files =
exist, but the "HOTSPOT_DIST" directory structure has not been created, =
with these files in the locations the build system expects. I'm sure =
that this is because of building a Compiler2 variant on a non-supported =
platform, as I don't have this issue with the Zero VM build. Thus, I =
manually created the "dist" structure and placed the files in the =
expected locations and the remainder of the build works as designed. =
Any thoughts?
I'm going to continue to stress test the build, to ensure everything is =
in working order.
Again, thanks for all the assistance.
Regards,
Curtis

Hi Curtis,
If SIGTRAP ist he problem, you could try -XX:-UseSIGTRAP.
This slows down null checks a bit, but this should not matter for now.
