There is a project with LTO patches and LTO enabled on the top of 5.18.3: https://build.suse.de/project/monitor/home:jirislaby:kernel-lto And the same source base, but LTO disabled by the config: https://build.suse.de/project/monitor/home:jirislaby:kernel-lto-disabled The diff between those is minimal: https://build.suse.de/package/rdiff/home:jirislaby:kernel-lto-disabled/kernel-source?opackage=kernel-source&oproject=home%3Ajirislaby%3Akernel-lto&rev=3 Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
