-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.
