Subject: [PATCH] Add step to find-debuginfo.sh script to compress annobin
|
|
|
672c60 |
notes.
|
|
|
672c60 |
|
|
|
672c60 |
With the introduction of the annobin gcc plugin to the build process,
|
|
|
672c60 |
built binary files have become larger. Sometimes significantly so.
|
|
|
672c60 |
This is a patch that adds a new step to the post-link process performed
|
|
|
672c60 |
by rpmbuild, to run the objcopy program with the --merge-notes option
|
|
|
672c60 |
specified. This will reduce the size of the annobin notes in binary
|
|
|
672c60 |
files, thus alleviating the size growth.
