[PATCH] D82282: [Support][AIX] Add declaration of wait4 to fix build

[Hubert Tong via Phabricator via llvm-commits]

hubert.reinterpretcast added inline comments.


================
Comment at: llvm/lib/Support/Unix/Program.inc:370
     WaitResult.Pid = wait4(ChildPid, &status, WaitPidOptions, &Info);
   } while (WaitUntilTerminates && WaitResult.Pid == -1 && errno == EINTR);
 
----------------
Got a build, but it hangs. Will need to check this loop.
```
