| 20 | """Build many configurations of glibc. | |
| 21 | ||
| 22 | This script takes as arguments a directory name (containing a src | |
| 23 | subdirectory with sources of the relevant toolchain components) and a | |
| 24 | description of what to do: 'checkout', to check out sources into that | |
| 4d602bce | 25 | directory, 'bot-cycle', to run a series of checkout and build steps, |
| a1f6a9ab JM |
26 | 'bot', to run 'bot-cycle' repeatedly, 'host-libraries', to build |
| 27 | libraries required by the toolchain, 'compilers', to build | |
| 28 | cross-compilers for various configurations, or 'glibcs', to build | |
| 29 | glibc for various configurations and run the compilation parts of the | |
| 30 | testsuite. Subsequent arguments name the versions of components to | |
| 31 | check out (<component>-<version), for 'checkout', or, for actions | |
| 32 | other than 'checkout' and 'bot-cycle', name configurations for which | |
| 33 | compilers or glibc are to be built. | |
