            Bug ID: 27190
           Summary: m68k: fmovemx does not accept pc-relative addressing
                    modes for memory-to-register transfers
           Product: binutils
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: admin@tho-otto.de
  Target Milestone: ---

Created attachment 13121
  --> https://sourceware.org/bugzilla/attachment.cgi?id=13121&action=edit
Add fix for gas not allowing pc-relative addressing for fmovemx <ea>,<list>

Assembling an instruction like


   fmovem.x addr(%pc),%fp0-%fp1


Is rejected by gas. For memory-to-register-transfers, it should also allow
pc-relative addressing modes. Attached is proposed fix (changes the
"alterable-control" flag to "control" for those instructions).
