Subject: [C++11] Fix break due to MSVC bug.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=873c5898895cd12713e4be6dc2f115418ac4c83e;p=oota-llvm.git

[C++11] Fix break due to MSVC bug.

MSVC (2012, 2013, 2013 Nov CTP) fail on the following code:

int main() {
  int arr[] = {1, 2};
  for (int i : arr)
    do {} while (0);
}

The fix is to put {} around the for loop. I've reported this to the MSVC
team.
