Subject: [Bug default/27363] New: Emit more detailed diagnostic output for "Unknown DWARF"
Date: Sun, 07 Feb 2021 11:06:43 +0000 [thread overview]
Message-ID: <bug-27363-11298@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=27363
Bug ID: 27363
Summary: Emit more detailed diagnostic output for "Unknown
DWARF"
Product: dwz
Version: unspecified
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: default
Assignee: nobody at sourceware dot org
Reporter: d.filder at web dot de
CC: dwz at sourceware dot org
Target Milestone: ---
The terseness of the current "Unknown DWARF" error messages makes it
very difficult to analyze what is going on in cases of not yet
parseable or standard-violating DWARF data. They should give more
information, namely include:
- a hexdump of the data around the offending entity,
- whether the entity is invalid (get_DW_*_name()==NULL) or merely not
yet handled by the code,
- current values of DW_AT_{name,producer,comp_dir,language,...},
- and instructions to include that output in the bug report and retain
a copy of the unstripped binary for upload upon request.
From my cursory understanding the 3rd item might be easily
implementable with global variables holding copies of the most
recently seen values.
Regards,
Dennis.
