I think this JEP is primarily about updating the HotSpot-specific subset of C++ and usage guidance to include some C++14 features. HotSpot usage is already different in some ways from C++ code in other parts of the JDK. For example, HotSpot code doesn't use global operator new; that isn't likely to change, and non-HotSpot code doesn't have access to the alternatives defined and used but not exported by HotSpot. As a necessary prerequisite for that, the JDK build system is being updated to enable the use of C++14 features. It's probably possible to limit the scope of the language change to HotSpot, but that doesn't seem useful. It also probably wasn't possible while Solaris was still in the mix. It is expected that groups responsible for other parts of the JDK will also want to take advantage of that build change, but I think it's up to those other groups to decide on an adoption strategy. I have no reason to think the choices being suggested here as appropriate for HotSpot are appropriate JDK-wide. I can't say whether a JEP is generally needed; maybe it's simply "C++14 - yes" in some areas. Also, some of the reasons for this being a JEP no longer apply. For example, Solaris was going to require at least a major ABI change, and at the time the JEP was created there was no path to C++14 for the AIX/PPC port; both of those needed visibility and discussion that seemed best provided via the JEP process. > -phil. > > On 6/13/20, 8:48 PM, Kim Barrett wrote: >>> On Jun 10, 2020, at 2:26 AM, Kim Barrett<kim.barr...@oracle.com> wrote: >>> >>>> On Jun 8, 2020, at 4:07 PM, Philip Race<philip.r...@oracle.com> wrote: >>>> BTW the JEP (https://bugs.openjdk.java.net/browse/JDK-8208089) still says >>>>> For Solaris: Add the -std=c++14 compiler option. ..... >>>> So I am sure there is still some room to update the JEP :-) >>> Yeah, I have some updates to make.
