It is a simple yet efficient solution. Also provided is a solution for\nthe ABA problem that relies on CMPXCHG16B Intel instruction for Double-Word Compare-And-Swap.\nWe require `unmanaged` classes; currently this will leak memory if you do not have safe memory-management solution.

As well, when you compile you _must_ build with\n`CHPL_LLVM` set (I.E to `CHPL_LLVM=llvm` or `CHPL_LLVM=system`) as the program uses `extern`\nblocks.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flouisjenkinscs%2Flocalatomics","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flouisjenkinscs%2Flocalatomics","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flouisjenkinscs%2Flocalatomics/lists"}
