- Axe -mpreferred-stack-boundary=2 as -Os turns this on by default.
- Axe -fdata-sections as turning it on or off makes no difference. If it did make a difference it would serve to bloat boot2 even further with extra padding. - Axe -fforce-addr. This gets us 32 bytes so we are down to only being 64-bytes over. We still can't compile this with gcc 3.1. The problem seems to be that the -fno-align-foo options don't actually work. Comparing the new and old output it turns out that gcc is 4-byte padding all the functions and labels and what not despite the passed in arguments thus adding the unfortunate bloat to boot2.
