== 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
