commit 13daa8e4889a971309f7d46a8d49129cb26088a5 Author: Andreas Krebbel <krebbel@linux.ibm.com> Date: Fri Nov 9 11:00:47 2018 +0100 S/390: Fix optional operand handling after memory addresses Instructions having an optional argument following a memory address operand were not handled correctly if the optional argument was not specified. gas/ChangeLog: 2018-11-09 Andreas Krebbel <krebbel@linux.ibm.com> * config/tc-s390.c (skip_optargs_p): New function.
