From f1cdc73f78a2f9b6499b4a5462485a873d9620af Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add basic find-debuginfo script tests
Covers basic find-debuginfo script functionality. Checks .debug files
are generated by eu-strip, .gnu_debugdata is generated, .gdb_index is
added by gdb-add-index, dwz multi file is created and all debugsources
are found, also does parallel runs. Skips dwz testing if .debug_addr
is generated (since dwz currently doesn't handle that).
* configure.ac: Check whether -gdwarf-5 produced DWARF5 .debug_addr.
* tests/atlocal.in: Add DWARF_5_DEBUGADDR.
* tests/Makefile.am (TESTSUITE_AT): Add find-debuginfo.at.
* tests/testsuite.at: m4_include find-debuginfo.at.
* tests/find-debuginfo.at: New test file.

Subject: [PATCH] debug_str_offsets header version and padding are 2 bytes, not
4 bytes
Reading too much bytes for the header made debugedit skip the first
actual string offsets table entry.

Subject: [PATCH] debugedit: Handle unused .debug_str_offsets entries
As a sanity check we would assert when rewriting a .debug_str index we
hadn't seen while processing the DWARF. This relies on the DWARF
producer/compiler to not emit strings that aren't used. So when
processing/rewriting the .debug_str_offsets we assume all indexes
point to .debugstr offsets we have seen before.
This assumption doesn't seem to hold for clang++ at the moment. It
does put strings in the .debug_str section referenced from the
.debug_str_offsets section that aren't used anywhere else. So
debugedit will fail with an assert when processing such files.
We don't want to process the .debug_str_offsets section multiple time
and possibly have to rewrite other str references in other
sections. So instead when we encounter an unseen/unused string we
replace it with a dummy string "<debugedit>".
To help DWARF producers indentify these unused strings we keep a
reference to the original string table and produce a warning
explaining which .debug_str_offsets table at which index points to the
unseen .debug_str offset.
debugedit: Warning, .debug_str_offsets table at offset ce2d0 index

stridxentry.

From 64d61a5f7d0ed685880f5c4f4b91f967445ba3a9 Mon Sep 17 00:00:00 2001
From: Mark Wielaard <mark@klomp.org>
Date: Thu, 16 Jan 2025 12:02:11 +0100
Subject: [PATCH] find-debuginfo: Fix skip_mini (".gnu_debugdata") handling
The conditional that tests $skip_mini for true/false was inadvertently
flipped, causing the add_minidebug() function to no longer run for the
otherwise eligible binary files.
Fixes: 971a74d79b48 ("find-debuginfo: Check files are writable before modifying them")

debugedit: Use standard libelf elf_strptr
The strptr function in debugedit.c does the same thing as libelf
elf_strptr. But elf_strptr handles bounds checks and invalid section
offsets better. And elf_strptr handles compressed sections.
* tools/debugedit.c (strptr): Just call elf_strptr.

commit c156ae62c3913aa86bd4cd4abda93772747e029f
Author: Morten Linderud <morten@linderud.pw>
Date: Sun Nov 6 18:10:23 2022 +0100
debugedit: decompress (and recompress) DWARF sections
When encountering compressed DWARF section try to decompress them
before rewriting. Afterwards recompress them. All this is
automatic. No new command line options.
Decompression was added by Morten, Mark then added recompression.
The recompression support needed a bit of workaround for an elfutils
< 0.192 bug https://sourceware.org/bugzilla/show_bug.cgi?id=32102
Various new tests were added. In debugedit.at DEBUGEDIT_SETUP now
takes an (optional) second arg to set the -gz=... option. readelf is
now called with -zp to automatically decompress any compressed
data/string sections.

commit 971a74d79b48a19ff1446642f39b3c5a8a7db238

find-debuginfo: Check files are writable before modifying them
Since commit dfe1f7ff3 ("find-debuginfo.sh: Exit with real exit status
in parallel jobs") there is a check whether gdb-add-index worked
correctly and find-debuginfo would fail (even in parallel mode) if an
error occured.
This turned out to show that gdb-add-index needs write permission to
add the gdb index to the file. This is also the case for a couple of
other things, like running objcopy --merge-notes. debugedit and
add_minidebug already made sure it had write permission.
To make sure find-debuginfo doesn't (partially) fail extend the
writable check to include the gdb-add-index and objcopy --merge-notes
invocation.

commit a359559d4a7696a415cfec5f924363d26cb9a4eb
Author: Mark Wielaard <mark@klomp.org>

debugedit: Handle DWARF5 DW_UT_type (Unit type 2) in ET_EXE/DYN
Handle DW_UT_type as if it is a DW_UT_compile unit by skipping the
type id and offset in the header. Which are the only differences with
DW_UT_compile. And the id and offset don't need to be rewritten. This
doesn't handle debug types in objects or partial linked (ET_REL) files
that contain COMDAT sections (because debugedit doesn't handle more
than one debug_info section). Add a testcase for foobarbaz.exe.
