            Bug ID: 110061
           Summary: libatomic: 128-bit atomics should be lock-free on
                    AArch64
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: wilco at gcc dot gnu.org
  Target Milestone: ---

128-bit atomics should be lock-free on AArch64. This is what most users expect,
gives better performance and makes it possible to inline/outline the recently
added 128-bit atomic instructions. It also makes GCC and LLVM ABI compatible
(since LLVM atomics are always lock-free).
