Hello,
with this move to t-bpabi other targets like RTEMS profit also from this
change. This is very good since the unwinder pull-in for 64-bit divisions was
pretty bad for small Cortex-M3 systems with internal flash only.

Hi,
lower-subreg.c goes completely bonkers at times with code
that uses the large vector modes, especially the vld3 / vst3
type operations. In these cases these large modes are usually
split into SImode moves which then cause massive spilling

Hi,
I've been investigating a patch which we've been using locally to fix
an issue with backtraces (using, e.g., glibc's backtrace() function)
through C++ exception-handling constructs on ARM. The original author of
the patch was Daniel Jacobowitz (please correct me if my understanding
is wrong!).
This makes into-SSA no longer rely on variable annotations and instead
uses on-the-side information local to into/update-SSA. Lookups can
probably be avoided in some places if we pass around the auxiliar
information instead of looking it up all the time.

This patch implements a new lock-free restriction. Thus, implicit dereferences
of access values prevent, as well as explicit dereference, the lock-free
implementation of protected objects.

This fixes the de-canonicalization of commutative GIMPLE operations in
the vectorizer that occurs when processing reductions. A loop_vec_info
is flagged for cleanup when a de-canonicalization has occurred in that
loop, and the cleanup is done when the loop_vec_info is destroyed.
