Subject: [PATCH 2/2] x86: use stderr if insn sanity test fails
Date: Tue, 25 Oct 2016 22:56:05 +0200
Message-ID: <1477428965-20548-3-git-send-email-pebolle@tiscali.nl> (raw)
In-Reply-To: <1477428965-20548-1-git-send-email-pebolle@tiscali.nl>

If the instruction sanity test fails, it prints a "Failure" message to
stdout. Make this program behave like the rest of the build and print
that message to stderr.
