Hi,

This month, I spent some time on the ring0 packages to ensure that they can all be built reproducibly, if it were not for this Profile-Guided-Optimisations (PGO).
One idea for gcc is to have two versions - one fast and one reproducible that differ by approx 8% in performance, but produce identical .o files.

Here are the autogenerated bits:
last month's status:
https://lists.opensuse.org/archives/list/factory@lists.opensuse.org/thread/G5MQCF65GZGNUTK3P5BBXK3RW5IP5ZEH/

Last months' reproducible builds project updates (including my work):
https://reproducible-builds.org/reports/2024-05/

I uploaded https://rb.zq1.de/compare.factory-20240630/ today

https://rb.zq1.de/spec/glossar.txt explains the meaning of below values:
total-packages: 15549 (+52)
build-tried: 15491 (+52)
build-failed: 22 (+4)
build-n-a: 193 (-3)
build-succeeded: 15276 (+51)
build-official-failed+na: 39 (-18)
build-compare-failed: 154 (+0)
build-compare-succeeded: 15122 (+51)
verify-failed: 234 (-76)
verified-semi-reproducible: 14855 (+133)
verified-bit-identical: 13545 (+35)
bit-by-bit-identical: 14622 (+135)
not-bit-by-bit-identical: 647 (-82)
not-bit-by-bit-identicalcheck: 654 (-84)

https://rb.zq1.de/compare.factory-20240630/graph.png
shows the change over time

https://rb.zq1.de/compare.factory-20240630/unreproduciblerings.txt
lists very unreproducible core packages (bootstrap+DVD)

Of the badly unreproducible packages,
5 were in ring0
35 were in ring1

That makes it 40/4043 => 0.99 %
which is below the overall average of
154/15276 => 1.01 %

647/15276 => 4.24 % of packages are not perfectly reproducible
