H8/300 Options

These -m options are defined for the H8/300 implementations:

-mrelax

Shorten some address references at link time, when possible; uses the linker option -relax. See ld and the H8/300, for a fuller description.

-mh

Generate code for the H8/300H.

-ms

Generate code for the H8S.

-mn

Generate code for the H8S and H8/300H in the normal mode. This switch must be used either with -mh or -ms.

-ms2600

Generate code for the H8S/2600. This switch must be used with -ms.

-mint32

Make int data 32 bits by default.

-malign-300

On the H8/300H and H8S, use the same alignment rules as for the H8/300. The default for the H8/300H and H8S 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.
