Bug ID: 31085
Summary: Provide tool to extract path to .dwo from binary
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tools
Assignee: unassigned at sourceware dot org
Reporter: sam at gentoo dot org
CC: arsen at sourceware dot org, elfutils-devel at sourceware
dot org
Target Milestone: ---
It would be nice if elfutils provided a tool to find the .dwo path embedded in
a binary with gcc's -gsplit-dwarf (extract '.debug_str' to find the .dwo path).
```
echo 'int main() {}' > /tmp/foo.c
gcc /tmp/foo.c -ggdb3 -o /tmp/foo -gsplit-dwarf
```
/tmp/foo might be moved after the build (e.g. installed by the build system to
DESTDIR). I need a way to map /tmp/foo -> /tmp/foo.dwo by reading .debug_str
from /tmp/foo.
(The reason being: I might have a lot of binaries in my DESTDIR. I need to know
which of them have debug information available & where it is, so I can copy
them into the DESTDIR too in e.g. /usr/lib/debug).
