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=elfutils.git;a=blob;f=backends/riscv_init.c;h=551e7bb6d34942222a1627e98de91208ef8261af;hb=HEAD#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.
