[8u-dev] RFR+RFA (M): JDK-8176100: [REDO][REDO] G1 Needs pre barrier on dereference of weak JNI handles

[Hohensee, Paul]

Thank you, Andrew. Oracle indeed doesn't support sparc starting with 12, and never paid much attention to linux-sparc.

    I saw the original post, but I'm waiting on the review outcome before
    approving a patch of this size with arch-specific changes.
    
    I'd also like to see some response with regards x86 & ppc. I think sparc
    may lack support, going forward, and I don't think Oracle were even
    particularly maintaining Linux+SPARC. Last time I asked around, I
    couldn't find anyone with a machine to test it on. It looks like there
    may be some in the GCC compile farm now [0], so I'll try and take a
    look, unless anyone has any better offers.
