            Bug ID: 31325
           Summary: mips: clone3 is wrong for o32
           Product: glibc
           Version: 2.39
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: adhemerval.zanella at linaro dot org
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

The mips clone3 (sysdeps/unix/sysv/linux/mips/clone3.S) does not take in
consideration that the cprestore might generate the gp save on the stack (so
clone3 must allocate some space before issuing the syscall) and $8 is not
guarantee by the kABI to be preserved after the syscall.
