Bug ID: 32914
Summary: dwp is silent on missing dwo references in executable
Product: binutils
Version: 2.45 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: vries at gcc dot gnu.org
CC: ian at airs dot com
Target Milestone: ---
There are two ways to specify input dwo files for dwp.
Either:
- you specify dwo files explicitly, or
- you specify an executable, and then dwp has to find the dwo references in the
executable.
Now say we don't specify an executable, and no dwo files either, we get a fatal
error:
...
$ dwp -o a.out.dwp
/home/vries/binutils/install/bin/dwp: fatal error: no input files and no
executable specified
...
However, say we generate an a.out without dwo file references:
...
$ g++ test.cc -g
$ dwp -e a.out
$
...
That happens silently.
Essentially this is another case of "no input files", and should probably also
produce an error.
