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:
architecture-vendor-os
For example, you can use the alias sun4 as a host argument,
or as the value for target in a --target=target
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
abbreviations--for example:
% sh config.sub sun4 sparc-sun-sunos4.1.1 % sh config.sub sun3 m68k-sun-sunos4.1.1 % sh config.sub decstation mips-dec-ultrix4.2 % sh config.sub hp300bsd m68k-hp-bsd % sh config.sub i386v i386-unknown-sysv % sh config.sub i786v Invalid configuration `i786v': machine `i786v' not recognized
config.sub is also distributed in the GDB source
directory (`gdb-4.12', for version 4.12).
