python src/build.py
Build.py has 3 types of actions:
Each of these types has multiple steps (e.g. a build step for each component). If you run build.py with no arguments, it will run all the sync, build, and test steps. If you make a change and only want to run a subset of steps, you can apply filters from the command line, via exclusions (to prevent specified steps from running) or inclusions (to run only the specified steps). Sync, build, and test exclusions are specified separately. For example:
$ src/build.py --no-sync --build-exclude=llvm
$ src/build.py --sync-include=wabt --build-include=wabt,binaryen --test-exclude=emtest,emtest-asm
The script should throw an error if you specify nonexistent steps or if you specify both includes and excludes for the same type of action.
When run, the script creates a directory src/work
inside the waterfall‘s git checkout. All modifications are made inside this directory (checking and out and building the sources, as well as the test builds and execution results). You can also use the git checkouts (e.g. src/work/llvm
) with your own branches; the sync steps will check out the latest revision from the script’s remote repositories but will not overwrite or destroy any local work.
