jdk8u-dev MacOS 10.15+ build environment?

[Hohensee, Paul]

Restarting this thread. We at Amazon have been building 8u using Xcode 12 for some months, see Ben Taylor's post

https://mail.openjdk.java.net/pipermail/jdk8u-dev/2021-March/013558.html

so that’s what we'd like to see targeted. Several backports have already been done (8200550, 8230428, 8077364, 8055754, 8033289) and another is tagged (8253375).

Thanks,
Paul

From what I remember, they were not proposed as backports but as a separate
patch without the source history.

I can't see a problem with most of the changes proposed, particularly if they
only touch a build configuration (Mac OS) which doesn't work at present.

Patches like https://cr.openjdk.java.net/~phh/jdk8u-xcode12-patches/hotspot/8033289.patch
I've backported myself a long time ago in IcedTea.

Which version of clang are we targetting? As I said before, with the shared code,
a lot of this seems to be warnings from a particular version of clang that will
likely be the same on other platforms, and so can be reproduced without needing
Mac OS.
