Subject: [PATCH 1/4] find-debuginfo: Pass -j down to dwz
|
|
|
|
Now that dwz 0.15 supports parallel jobs, add a way to control it from
|
|
here. find-debuginfo already has a -j parameter so we can just extend it
|
|
and pass the value down to dwz as well.
|
|
|
|
This should fix building large packages on memory constrained builders,
|
|
such as webkitgtk on s390x in Fedora koji build system, where we can now
|
|
use the -j option to tune down parallelism to avoid running out of
|
|
memory during dwz run.
|
|
|
|
Add a configure check to make sure the installed dwz supports the
|
|
-j option.
