- Subject: [PATCH 0/4] Improve elfutils diagnostics
Hi,
This patch series attempts to improve elfutils feedback to help guide
the user towards fixing erroneous situations.
The first two patches enable elfutils to give a more specific error when
compressed sections fail to be decompressed.
The third patch add the new function dwfl_errmsg_details(), which can be
used to provide dynamic freeform information to the user to supplement
the static error message from dwfl_errmsg().
The fourth patch makes use of this facility to provide the user with all
the paths that were attempted while looking for the debug file.
Suggestions and comments welcome!
