+Subject: [PATCH] [SystemZ] Improve error messages for unsupported relocations
+
+In the SystemZMCObjectWriter, we currently just abort in case
+some unsupported relocation in requested.  However, as this
+situation can be triggered by invalid (inline) assembler input,
+we should really get a regular error message instead.
