> Please review this change to the HotSpot Style Guide to suggest that C++ > Standard Library components may be used, after appropriate vetting and > discussion, rather than just a blanket "no, don't use it" with a few very > narrow exceptions. It provides some guidance on that vetting process and > the criteria to use, along with usage patterns. > > In particular, it proposes that Standard Library headers should not be > included directly, but instead through HotSpot-provided wrapper headers. This > gives us a place to document usage, provide workarounds for platform issues in > a single place, and so on. > > Such wrapper headers are provided by this PR for `<cstddef>`, `<limits>`, and > `<type_traits>`, along with updates to use them. I have a separate change for > `<new>` that I plan to propose later, under JDK-8369187. There will be > additional followups for other C compatibility headers besides `<cstddef>`. > > This PR also cleans up some nomenclature issues around forbid vs exclude and > the like. > > Testing: mach5 tier1-5, GHA sanity tests
