== Progress ==
* Neon vext support for builtin_shuffle:
* Committed vext patch upstream, as well as a small cleanup patch.
* Merged vext support into gcc-linaro/4.7 branch.
* Posted upstream a follow-up patch to make vext tests support
big-endian.
Filed PR 54517: wrong code generation in big-endian with inline in
these tests.
* Updated patch to fix 3 testcases in big-endian after upstream comments.
* Implement builtin_bswap16:
* Posted upstream a patch to implement bswap16. Discussion on-going,
to have less duplication between arm and thumb patterns.
* Investigating how to make GCC catch the (x<<8)|(x>>8) construct
(where x is unsigned short) and map it to rev16, like
builtin_bswap16.
== Next ==
* Continue with bswap16 support.
