Subject: [PATCH] configure: fix --enable-fuzzing linker failures
Date: Sun, 21 Feb 2021 11:00:44 -0500 [thread overview]
Message-ID: <20210221160044.28581-1-alxndr@bu.edu> (raw)
With --enable-fuzzing, QEMU_CFLAGS include -fsanitize=fuzzer-no-link.
This should allow us to build non-fuzzer binaries using objects
instrumented for fuzzing. However, to do that, we also need to link with
-fsanitize=fuzzer-no-link. We were not doing that.
