Re: msp430-elf size optimizations - some notes and a patch

Is it the intent to fully support C++ in this port, inclusive of
static initializers and exceptions?   (Exclusive of features that
require host support like threads, though it'd be good if <chrono>
could be used with various MSP430 clocks providing the underlying
timers.)

Proper support for C++11 in msp430-elf-gcc sometime soon would be one
of the things that will slow my move to ARM-based microcontrollers.  I
can respect flags that disable its support; I don't want to have to
add flags to put support back, or find language-mandated features do
not work.  (The move to ARM is inevitable, though; MSP430 just doesn't
stack up so well anymore, even for ultra-low-power applications).

Subversion Kills Productivity. Get off Subversion & Make the Move to Perforce.
With Perforce, you get hassle-free workflows. Merge that actually works. 
Faster operations. Version large binaries.  Built-in WAN optimization and the
freedom to use Git, Perforce or both. Make the move to Perforce.
