New Revision: 278722
URL: http://llvm.org/viewvc/llvm-project?rev=278722&view=rev
Log:
Use -O1 when testing with ASAN and MSAN to prevent Clang OOM errors.
Currently certain tests get killed when compiled with ASAN at -O0 because
they eat all of the systems memory. This doesn't happen at -O1, so enable that
to work around the issue.
