Ok, this is the part I don't really understand yet. Why run with Zero on
Linux/sparc64? Shouldn't it be possible to run HotSpot "natively" (with
the template interpreter, C1, C2) on Linux/sparc64?
The first three patches are needed to get native Hotspot to build on
Linux sparc. Without the patches, the builds bails out with compiler
errors.
So, should I just run the testsuite with all three patches applied?
Yes, please run the testsuite with the three patches applied. This
should work (famous last words ;)) for the "native" Linux/sparc64
version of hotspot (if not, I would to curious to learn why). To test
Linux/sparc64+zero you obviously need the fourth patch applied as well.
The fourth patch just fixes Zero on Linux sparc. If I understand
correctly, Debian's openjdk packages always build the Zero VM even on
targets with a native Hotspot. And without the last patch, the Zero
build fails on Linux sparc.
Ah, now I think I get it :) This is for the openjdk-9-jre-zero package,
right? Does the openjdk-9-jre package provide the "native" (using
template interpreter, C1, C2) version of hotspot if possible?
Thanks,
