New Revision: 258902
URL: http://llvm.org/viewvc/llvm-project?rev=258902&view=rev
Log:
Adding a test for PR25717.
The test tries to produce a large preprocessed output to the console, and checks
that we do not see any unexpected fatal errors.
The test is not enabled unless a lit parameter "--param enable_console=1" is
passed on the command line to lit.py.
