[ACTIVITY] Sep 24-Sep 28

== 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.
