== Progress == * AArch64 frame grows downward: no feedback yet.

* Disable-peeling: Vectorizer cost model has been changed upstream, the current default now includes the effect of disabling peeling. I have submitted benchmark jobs to check the exact effet; expecting some regressions since the reduced test case I was working on now generates the same code as with my patch.

* AArch64 bootstrap failure: build it still on-going, so still hoping to reproduce it.

* GCC trunk validation: - good progress on reporting - cross-validating several configurations (currently 18) for each upstream commit is too much for our compute farm to handle. Reduced to patches related to ARM/AArch64, but then we can miss regressions caused by other generic patches.

* Backports: - committed a few simple ones.

== Next == * AArch64 frame grows downward: continue * Disable-peeling/new vectorizer cost model: analyze bench results * Backports : check which ones can be reasonably done
