Subject: [test] Use printf instead of C++ iostream, NFC.
X-Git-Tag: llvmorg-7.0.0-rc1~495
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a7c9fe3762de3701bf6aea68fec382a046288353;p=platform%2Fupstream%2Fllvm.git

[test] Use printf instead of C++ iostream, NFC.

This test fails with libc++ when built with MemorySanitizer. This
is because we link to an uninstrumented version of the library
so msan detects a nested error when calling std::cout << "...".
This can be easily avoided by using good old printf.
