H8/300 Options
Shorten some address references at link time, when possible; this option uses
the linker option, -relax. See “ld and the H8/300” in Using LD in GNUPro Utilities for a fuller description.
Generate code for the H8/300H.
Make int data 32 bits by default.
On the H8/300H, use the same alignment rules as for the h8/300. The default for the H8/300H is to align longs and floats on 4 byte boundaries.
-malign-300 causes them to be aligned on 2 byte boundaries. This option has no effect on
the H8/300.
