X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=7185e6564d47f48d5bc041678d72b762dbabe15f;p=FUZIX.git

6809: Switch to -Os

We've updated the helpers so can now do this.

A minimal build 6809 image currently weighs in at 24K code, 8K data. Some
of this is the CPU, some the calling conventions, and some gcc.
