Subject: <rdar://problem/13190981>
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3f875c589fb6b581429d422b4257e7eb325bcbb2;p=platform%2Fupstream%2Fllvm.git

<rdar://problem/13190981>

Fixed an issue where if we got a 'A' async packet back from debugserver, we would resend the last continue command. We now correctly identify the packet as async (just like the 'O' stdout async packet) and we don't resend the continue command.
