The specifications used for hosts and targets in the configure script are based on a three-part naming scheme, but some short predefined aliases are also supported. The full naming scheme encodes three pieces of information in the following pattern:
For example, you can use the alias
sun4 as a host argument,
or as the value for target in a
option. The equivalent full name is ‘sparc-sun-sunos4’.
The configure script accompanying GDB does not provide
any query facility to list all supported host and target names or
aliases. configure calls the Bourne shell script
config.sub to map abbreviations to full names; you can read the
script, if you wish, or you can use it to test your guesses on
% sh config.sub i386-linux i386-pc-linux-gnu % sh config.sub alpha-linux alpha-unknown-linux-gnu % sh config.sub hp9k700 hppa1.1-hp-hpux % sh config.sub sun4 sparc-sun-sunos4.1.1 % sh config.sub sun3 m68k-sun-sunos4.1.1 % sh config.sub i986v Invalid configuration `i986v': machine `i986v' not recognized
config.sub is also distributed in the GDB source
directory (gdb-188.8.131.5230331-git, for version 184.108.40.20630331-git).
