Параметры подробно (Options detail)

H8/300

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.

       -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.

       -mexr
           Extended registers are stored on stack before execution of
           function with monitor attribute. Default option is -mexr.
           This option is valid only for H8S targets.

       -mno-exr
           Extended registers are not stored on stack before execution
           of function with monitor attribute. Default option is
           -mno-exr.  This option is valid only for H8S targets.

       -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.
