[Petr Hosek via Phabricator via cfe-commits]

================
Comment at: compiler-rt/lib/profile/InstrProfilingPlatformLinux.c:265-267
+COMPILER_RT_VISIBILITY
+void *__llvm_profile_keep[] = {(void *)&dummy_cnts, (void *)&dummy_data,
+                               (void *)&dummy_name, (void *)&dummy_vnds};
----------------
Does AIX linker support the `retain` attribute? That would be a cleaner solution.


================
Comment at: compiler-rt/lib/profile/InstrProfilingRuntime.cpp:20-22
 COMPILER_RT_VISIBILITY int INSTR_PROF_PROFILE_RUNTIME_VAR;
-}
 
+static int Registration = RegisterRuntime();
----------------
Is it possible to reuse the runtime hook variable on other platforms as well? I'd really like to avoid introducing another variable.
