 Target Selection
 ================
 
    A "target" is an object file format.  A given target may be
 supported for multiple architectures ( Architecture Selection).
 A target selection may also have variations for different operating
 systems or architectures.
 
    The command to list valid target values is `objdump -i' (the first
 column of output contains the relevant information).
 
    Some sample values are: `a.out-hp300bsd', `ecoff-littlemips',
 `a.out-sunos-big'.
 
    You can also specify a target using a configuration triplet.  This is
 the same sort of name that is passed to `configure' to specify a
 target.  When you use a configuration triplet as an argument, it must be
 fully canonicalized.  You can see the canonical version of a triplet by
 running the shell script `config.sub' which is included with the
 sources.
 
    Some sample configuration triplets are: `m68k-hp-bsd',
 `mips-dec-ultrix', `sparc-sun-sunos'.
 
 `objdump' Target
 ----------------
 
    Ways to specify:
 
   1. command line option: `-b' or `--target'
 
   2. environment variable `GNUTARGET'
 
   3. deduced from the input file
 
 `objcopy' and `strip' Input Target
 ----------------------------------
 
    Ways to specify:
 
   1. command line options: `-I' or `--input-target', or `-F' or
      `--target'
 
   2. environment variable `GNUTARGET'
 
   3. deduced from the input file
 
 `objcopy' and `strip' Output Target
 -----------------------------------
 
    Ways to specify:
 
   1. command line options: `-O' or `--output-target', or `-F' or
      `--target'
 
   2. the input target (see "`objcopy' and `strip' Input Target" above)
 
   3. environment variable `GNUTARGET'
 
   4. deduced from the input file
 
 `nm', `size', and `strings' Target
 ----------------------------------
 
    Ways to specify:
 
   1. command line option: `--target'
 
   2. environment variable `GNUTARGET'
 
   3. deduced from the input file
 
 Linker Input Target
 -------------------
 
    Ways to specify:
 
   1. command line option: `-b' or `--format' ( Options
      (ld.info)Options.)
 
   2. script command `TARGET' ( Option Commands (ld.info)Option
      Commands.)
 
   3. environment variable `GNUTARGET' ( Environment
      (ld.info)Environment.)
 
      Emulation Selection::)
 
 Linker Output Target
 --------------------
 
    Ways to specify:
 
   1. command line option: `-oformat' ( Options (ld.info)Options.)
 
   2. script command `OUTPUT_FORMAT' ( Option Commands
      (ld.info)Option Commands.)
 
   3. the linker input target (see "Linker Input Target" above)
