[libcxx-commits] [PATCH] D113066: [libcxx][SystemZ][z/OS] Update libcxx/src/memory.cpp to accommodate POSIX(OFF)

[Jon Roelofs via Phabricator via libcxx-commits]

jroelofs added inline comments.


================
Comment at: libcxx/src/memory.cpp:152
 {
-    auto m = static_cast<__libcpp_mutex_t*>(__lx);
-    unsigned count = 0;
----------------

================
Comment at: libcxx/src/memory.cpp:195
     };
     return muts[hash<const void*>()(p) & (__sp_mut_count-1)];
 }
----------------
micro-optimization: when threading is disabled, always return `muts[0]`.
