Subject: Make frem.ll flush after calling printf.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7994fa0a0e9307a74615eaa105ab035a8505f48a;p=oota-llvm.git

Make frem.ll flush after calling printf.

Without this, the test was flaky, and FileCheck would sometimes
not detect any input on stdin.
