== Progress ==
* builtin_bswap16:
  * patch to catch (x<<8)|<x>>8) committed upstream after confirmation
    it was OK by PowerPC guys.

  * backporting of builtin_bswap16 for ARM to Linaro/4.7: one of the
    tests fails. Trying to isolate the trunk change that would make is
    pass.

  * useful discussions with Ulrich to investigate if we could avoid
    generating useless zero-extensions after rev16. I still need to
    experiment.

* PGO/hot-cold partitioning:
  * applied info from Matt, I have now a usable Spec2000 setup based
    on qemu.

== Next ==
* builtin_bswap16:
  * try to avoid useless zero-extensions.

* PGO/hot-cold partitioning:
  * investigate runtime failures.
  * run on a Snowball board.
