21 """Build many configurations of glibc.
23 This script takes as arguments a directory name (containing a src
24 subdirectory with sources of the relevant toolchain components) and a
25 description of what to do: 'checkout', to check out sources into that
26 directory, 'bot-cycle', to run a series of checkout and build steps,
27 'bot', to run 'bot-cycle' repeatedly, 'host-libraries', to build
28 libraries required by the toolchain, 'compilers', to build
29 cross-compilers for various configurations, or 'glibcs', to build
30 glibc for various configurations and run the compilation parts of the
31 testsuite. Subsequent arguments name the versions of components to
32 check out (<component>-<version), for 'checkout', or, for actions
33 other than 'checkout' and 'bot-cycle', name configurations for which
34 compilers or glibc are to be built.
36 The 'list-compilers' command prints the name of each available
37 compiler configuration, without building anything. The 'list-glibcs'
38 command prints the name of each glibc compiler configuration, followed
39 by the space, followed by the name of the compiler configuration used
40 for building this glibc variant.
