13.2. Architecture selection

An architecture is a type of cpu on which an object file is to run. Its name may contain a colon, separating the name of the processor family from the name of the particular cpu.

The command to list valid architecture values is "objdump -i" (the second column contains the relevant information).

Sample values: "m68k:68020", "mips:3000", "sparc".
