            Bug ID: 27925
           Summary: riscv backend only provides return value locations for
                    code compiled for LP64D ABI
           Product: elfutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: backends
          Assignee: unassigned at sourceware dot org
          Reporter: wcohen at redhat dot com
                CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

When diagnosing why a port of systemtap to riscv wasn't able to get $return
values from functions I found that the elfutils riscv backend initialization
code only sets up the return value location handler for the riscv for code =
that
is compiled for hardware floating point (LP64D):

https://sourceware.org/git/?p=3Delfutils.git;a=3Dblob;f=3Dbackends/riscv_in=
it.c;h=3D551e7bb6d34942222a1627e98de91208ef8261af;hb=3DHEAD#l67

elfutils dwfl_module_return_value_location() should still be able to provide
the location of the return value for riscv code for the other ABIs besides
LP64D.
