"""Build many configurations of glibc.
|
|
|
|
This script takes as arguments a directory name (containing a src
|
|
subdirectory with sources of the relevant toolchain components) and a
|
|
description of what to do: 'checkout', to check out sources into that
|
|
directory, 'host-libraries', to build libraries required by the
|
|
toolchain, 'compilers', to build cross-compilers for various
|
|
configurations, or 'glibcs', to build glibc for various configurations
|
|
and run the compilation parts of the testsuite. Subsequent arguments
|
|
name the versions of components to check out (<component>-<version),
|
|
for 'checkout', or, for actions other than 'checkout', name
|
|
configurations for which compilers or glibc are to be built.
