Hardware models and configurations

In Specifying target machine and compiler version, we discussed the standard option, ‘-b’, which chooses among different installed compilers for completely different target machines, such as VAX vs. 68000 vs. 80386.

In addition, each of these target machine types can have its own special options, starting with ‘-m’, to choose among various hardware models, or configurations—for example, 68010 vs. 68020, floating coprocessor or none. A single installed version of the compiler can compile for any model or configuration, according to the options specified.

Some configurations of the compiler also support additional special options, usually for compatibility with other compilers on the same platform.

The following documentation discusses options for the compiler on specific targets.
