[11u] Backport 8229352: Use of an unitialized register in 32-bit ARM template interpreter

[christoph.goettschkes at microdoc.com]

Hi Boris,

I have the following issue:

The hotspot tier1 JTreg tests do not show any regresseion (as with the 
jdk/jdk repository), but the CDS archive tests are failing (with and 
without the patch applied). I guess this would block the backporting. 
Should I already send you the "Fix Request" comment and file a new bug 
report for that?

I did not see this issue when I tested the jdk/jdk repository (not sure if 
the issue is there too). I guess this is due to the fact that I changed 
the test setup (I have to use a different test device right now).

Not even the following test works:

$ ./jdk/bin/java -cp $(pwd) -XX:+UnlockDiagnosticVMOptions 
-XX:SharedArchiveFile=$(pwd)/cds.jsa -Xshare:dump -version

I am not able to reproduce this issue on amd64, but it is present on 
32-bit ARM hard and soft float.

Thanks, Christoph
