            Bug ID: 24832
           Summary: mips: convert from data to object always generate MIPS
                    I
           Product: binutils
           Version: 2.33 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: syq at debian dot org
  Target Milestone: ---

$ echo "abc" > xx.dat
$ mips64el-linux-gnuabi64-ld -r -b binary xx.dat -o xx.o
$ file xx.o
xx.o: ELF 64-bit LSB relocatable, MIPS, MIPS-I version 1 (SYSV), not stripped

while to link xx.o with real mips64 objects, it fails:
