Bug ID: 23564
Summary: 7.7 regression: dwz: Missing DWZ common file filename
is no longer printed
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: symtab
Assignee: unassigned at sourceware dot org
Reporter: jan.kratochvil at redhat dot com
Target Milestone: ---

PASS:
GNU gdb (GDB) 7.6.1.20131021-cvs
Reading symbols from /tmp/usr/bin/echo...could not read
'/tmp/usr/bin/../../.dwz/coreutils-8.29-7.fc28.x86_64': No such file or
directory

FAIL:
GNU gdb (GDB) 7.7.1.20140611-cvs
Reading symbols from /tmp/usr/bin/echo...could not find '.gnu_debugaltlink'
file for /tmp/usr/bin/echo

It is more useful to know the filename than having to do:
$ objcopy -O binary --set-section-flags .gnu_debugaltlink=A -j
.gnu_debugaltlink /tmp/usr/bin/echo /proc/self/fd/1|perl -e 'undef
$/;$_=<>;s/\0.*/\n/s;print'
../../.dwz/coreutils-8.29-7.fc28.x86_64

Since this has been present since GDB 7.7, I don't think we can call this
critical for 8.2, can we?

--- Comment #2 from Jan Kratochvil <jan.kratochvil at redhat dot com> ---
It is definitely not a release blocker, just it would be nice if it gets fixed
in time to also still backport it to 8.2. But I do not plan to fix it myself so
I agree that 8.2 target milestone probably makes no sense.
