1 18.1 Target Selection
1 =====================
1
1 A "target" is an object file format. A given target may be supported
1 for multiple architectures (⇒Architecture Selection). A target
1 selection may also have variations for different operating systems or
1 architectures.
1
1 The command to list valid target values is 'objdump -i' (the first
1 column of output contains the relevant information).
1
1 Some sample values are: 'a.out-hp300bsd', 'ecoff-littlemips',
1 'a.out-sunos-big'.
1
1 You can also specify a target using a configuration triplet. This is
1 the same sort of name that is passed to 'configure' to specify a target.
1 When you use a configuration triplet as an argument, it must be fully
1 canonicalized. You can see the canonical version of a triplet by
1 running the shell script 'config.sub' which is included with the
1 sources.
1
1 Some sample configuration triplets are: 'm68k-hp-bsd',
1 'mips-dec-ultrix', 'sparc-sun-sunos'.
