== GCC related ==
* Launchpad #693686, GCC ARM segfault ICE when building Chromium in V8.
Spent some time reproducing; this ICE seems to be in the maverick
gcc-4.5, at the vectorizer phase. As the ICE happens in
tree-vect-stmts.c:supportable_widening_operation(), I'm suspecting
(without further verification yet) this might be due to vmovn not
backported? (Linaro 4.5 does has this ported I think)
* PR44557, Thumb-1 ICE. Looking further after seeing Richard Earnshaw's
comment on my patch. It would be nice if we could upgrade the entire
secondary reload bits, looking into this.
== This week ==
* Look into more GCC issues.
* Get some backports done.
