21 | """Build many configurations of glibc. | |
22 | ||
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 | |
4d602bce | 26 | directory, 'bot-cycle', to run a series of checkout and build steps, |
a1f6a9ab JM |
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. | |
4d602bce | 35 | |
feaa1506 FW |
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. | |
