RFR(S): 8067330 : ZERO_ARCHDEF incorrectly defined for PPC/PPC64 architectures

[Severin Gehwolf]

Hi,

Could someone please review and sponsor this fix for JDK-8067330? In
particular, the hotspot build expects either PPC64 or PPC32 to be
defined (hotspot/src/share/vm/utilities/macros.hpp:366) and if one of
them is indeed defined PPC gets defined as well. However if neither of
the two is defined then PPC gets silently undefined. This may result in
incorrectly generated code for the Zero variant build.

Bug: https://bugs.openjdk.java.net/browse/JDK-8067330

Thanks!

Cheers,
