            Bug ID: 28951
           Summary: eu-addr2line produces relative path names, should be
                    absolute
           Product: elfutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tools
          Assignee: unassigned at sourceware dot org
          Reporter: fche at redhat dot com
                CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

The behaviour binutils addr2line is more helpful, in that it prefixes relative
source filenames with the CU cwd.  This behaviour would make it more useful to
tools that mechanically process the source file names.

eu-readelf does have:

  -A, --absolute             Show absolute file names using compilation
                             directory

Which produces:

$ (echo 0; echo 0585b0) | eu-addr2line -A -e `debuginfod-find debuginfo
07ae52cfc7f4eda1d13383c04564e3236e059993`

We could make that the default maybe?

Sorry for not noticing the flag.  Making it default would let it match
binutils.  (Both also have the "-s" option for basename.)

Matching binutils addr2line would be good.
I also added a new --relative option to get the old default back.
(-s, --basenames, isn't exactly the same)

commit 9e39d31c4ec1c8f7eb16886f8b7fd04c0a4f2462
Author: Mark Wielaard <mark@klomp.org>
Date:   Fri Mar 11 15:44:21 2022 +0100

    addr2line: Make --absolute the default, add --relative option.

    Make --absolute (including the compilation directory in file names)
    the default and add a new option --relative to get the previous
    default behavior.
