ical challenges for implementing it with this method can be
solved.
I've attached 3 patches for reference:
- Binutils handling of SHF_GNU_RETAIN in binutils-SHF_GNU_RETAIN.patch
- New "retain" GCC attribute in gcc-retain-attribute.patch
- "used" applies SHF_GNU_RETAIN
correctly, so running at these optimization levels verifies the changes
in this patch.
Ok for trunk?

The length of an insn can be used to calculate its cost, when optimizing for
size. When optimizing for speed, this is a good estimate, since the cycle cost
of an MSP430 instruction increases with its length.
