Subject: Use -O1 when testing with ASAN and MSAN to prevent Clang OOM errors.
X-Git-Tag: llvmorg-4.0.0-rc1~12409
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d9ce2917390f3b9c28a6ee57536193cdf47d4db9;p=platform%2Fupstream%2Fllvm.git

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.
