C++17: compiler support for pmr namespace classes
I want to experiment with pmr::memory_resource for dynamic memory pooling.
This page and this page purport to list C++17 features and indicate compiler support for each. However, I do not find pmr, memory_resource or polymorphic_allocator listed here.
Also, what is the most recent proposal on these proposed features? I found this revised proposal from early 2014. Is that the latest?
Solution
Polymorphic allocator belonging to the pmr namespace are not compiler features; they're new standard library features. You should refer to these pages:
Note that polymorphic memory resources and polymorphic allocators are part of the "Library Fundamentals V1 TS Components for C++17".
libstdc++ supports it as part of GCC 9.1
libc++ support is marked as "in progress"
