== Progress == * Disable-peeling: - benchmarking locally on snowball - failed to build reference branch on cbuild, for an unknown reason

* Turnoff 64bits ops in Neon: - committed upstream in 4.9 (now stage 1) - benches of backport into Linaro-4.7 OK: no significant diff, except +12.6% on spec2k's crafty) - Filed merge request.

* Vectorizer cost model: - benches of backport inot Linaro-4.7 OK (no significant diff, as expected). - Filed merge request.

* Revert-coalesce: - benches ran in cbuild, but no *-diff.txt file generated.

* Libsanitizer: - testsuite results OK. All unsupported tests are normal.

* Neon intrinsics codegen: - got internal feedback

* GDB reverse debug: - filed 2 bug reports after internal requests.

* Misc: - filed several bug reports against cbuild to track the problems I observed.

== Next == * Disable-peeling: - analyze bench results - understand/'fix what's wrong with cbuild

* Turnoff 64bits ops in Neon: - backport to Linaro-4.8

* Revert-coalesce: - manually compute bench differences if unable to have cbuild do it.

* Libsanitizer: - propose patch upstream.
