RFR : 8231448: s390 and ppc - replace JVM type comparisons to T_OBJECT and T_ARRAY with call to is_reference_type

Wed Sep 25 13:08:01 UTC 2019

Hello, please review the following change .

Recently,  https://bugs.openjdk.java.net/browse/JDK-8230505

  replaced  a lot of  JVM conditionals compares against T_OBJECT and T_ARRAY   ( for readability and future extendability )  with a call to

is_reference_type .

However   the change  8230505    did not  change  the calls  in src/hotspot/cpu/ppc   and  src/hotspot/cpu/s390  .
My change  adjusts the remaining calls  in the  ppc / s390  coding .
