[PATCH 0/3] Uncontroversial improvements to C++20 wait-related implementation

[Thiago Macieira]

Discussion at:
https://gcc.gnu.org/pipermail/libstdc++/2021-February/052043.html

This patch set includes the uncontroversial parts that improve
performance but don't otherwise change ABI.

Please note we still need to decide on how to deal with the future ABI
break.

Thiago Macieira (3):
  Atomic __platform_wait: accept any 32-bit type, not just int
  std::latch: reduce internal implementation from ptrdiff_t to int
  barrier: optimise by not having the hasher in a loop
