Yes, code size is not as one might wish. See
http://e2e.ti.com/support/development_tools/compiler/f/343/p/384317/1356674#1356674
for some information, as well as
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64027
Those issues, unfortunately, are not solved by linker optimizations. (IRT
Eric: I was unaware of the visibility attribute, so haven't run into that,
though I can see it will be useful in the future.)
My core blockers for msp430-elf are an official patch for
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64160 and a new release of the
support headers/linker scripts that reverts the broken initialization
infrastructure (which I assume TI is working on).
But since mspgcc doesn't build on Ubuntu 14.04 the code size issue does
become more important. The E2E response hints that we're running into an
organizational conflict of interest at TI.
