Cross compile jdk8u on PPC32

'hotspot/src/cpu/ppc' only supports PPC64. I’m not so familiar with the zero build, but I’ve heard about people using zero on PPC32 (e.g. for Debian). Maybe one of them can provide hints.

Subject: Re: Cross compile jdk8u on PPC32
I am still having trouble compiling the 'zero' jvm-variant. I get C/C++ compiling errors I am trying to fix.
I looked in 'hotspot/src/cpu' and saw there are source-code folders for different cpu architectures: 'ppc', 'sparc', 'x86', 'zero'.
If I use jvm-variant 'zero' when compiling it will try to use the code from 'hotspot/src/cpu/zero'.
I looked in the mercurial commit logs and saw (I guess) commits for PPC being done in the folder 'hotspot/src/cpu/ppc'.
My question are to build for PPC 32 what source-code folder should I use 'hotspot/src/cpu/zero' or 'hotspot/src/cpu/ppc'?
Do I try to build/compile using jvm-variant 'zero' and force it to use the code from 'hotspot/src/cpu/ppc'?
Is the source-code from 'hotspot/src/cpu/ppc' onlu for PPC 64?
Thank you very much for the help,

That's wrong. Zero supports JNI just fine.
