Description
There should be a simple, documented script or build target to run all 3C tests that we believe should be run on every change. Obviously, a necessary condition for a test to be in this set is that it be fully automated (which the benchmark program tests aren't yet); beyond that, it's a policy decision of what tests are worth the running time, though we could conceivably have different modes.
It looks like clang/test/CheckedCRewriter/llvm-lit-wrapper.py
is trying to be what we want, but I'm getting an error even after I manually add build/bin
to $PATH
and llvm/utils/lit
to $PYTHONPATH
:
llvm-lit: /home/user/3c/llvm/utils/lit/lit/TestingConfig.py:101: fatal: unable to parse config file '/home/user/3c/clang/test/lit.cfg.py', traceback: Traceback (most recent call last):
File "/home/user/3c/llvm/utils/lit/lit/TestingConfig.py", line 90, in load_from_path
exec(compile(data, path, 'exec'), cfg_globals, None)
File "/home/user/3c/clang/test/lit.cfg.py", line 25, in <module>
config.test_format = lit.formats.ShTest(not llvm_config.use_lit_shell)
AttributeError: 'NoneType' object has no attribute 'use_lit_shell'
It would be even better to have a build target that won't rerun the tests if they previously passed and none of the dependencies have changed since then.
I want to have this script/target as a necessary (but not sufficient) element of testing the renames in #286.
