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.
