[PATCH] D58930: Add XCOFF triple object format type for AIX

Tue Mar 5 05:54:43 PST 2019

apaprocki added inline comments.

================
Comment at: lldb/source/Plugins/Process/gdb-remote/GDBRemoteCommunicationClient.cpp:2079
+          if (log)
+            log->Printf("sorry: unimplemented for XCOFF");
+          return false;
----------------
No need to be `sorry:` :) This should probably just say `error: XCOFF is unimplemented` to be more direct in case anything is expecting "error:" in the output.

================
Comment at: llvm/lib/Support/Triple.cpp:537
   return StringSwitch<Triple::ObjectFormatType>(EnvironmentName)
+    // FIXME: We have to put XCOFF before COFF;
+    // perhaps an order-independent pattern matching is desired?
----------------

Agreed, existing code seems fine as long as there is a comment explaining that `xcoff` must come before `coff` in case it isn't obvious at a quick glance.
