// Test misaligned reads and writes spanning cache line boundaries | |
// 2014-12-05 Eric Smith <spacewar@gmail.com> | |
// This program demonstrates that on an AMD FX-8350, and presumably | |
// other x86_64 processors, misaligned 64-bit reads and/or writes | |
// which span a cache line boundary are not atomic. For a | |
// "simultaneous" write and read of a misaligned value, the read may | |
// return a value that is partially the pre-write value, and partially | |
// the written value. |
