--- Comment #12 from tonyb at cybernetics dot com --- The patch fixed my own programs, so I rebuilt all of Yocto with -flto in two different directories. I found that most shared libraries in /lib and /usr/lib still have the problem (i.e. are still not binary reproducible), as well as binaries from pciutils, e2fsprogs, dropbear, sysvinit, hdparm, and a few other packages (they are all binary reproducible without -flto). However, the patch certainly did improve things, since some binaries that were different previously are now the same.
