Subject: [PATCH v6 15/16] fuzz: register predefined generic-fuzz configs
Date: Wed, 21 Oct 2020 17:09:21 -0400 [thread overview]
Message-ID: <20201021210922.572955-16-alxndr@bu.edu> (raw)
In-Reply-To: <20201021210922.572955-1-alxndr@bu.edu>
We call get_generic_fuzz_configs, which fills an array with
predefined {name, args, objects} triples. For each of these, we add a
new FuzzTarget, that uses a small wrapper to set
QEMU_FUZZ_{ARGS,OBJECTS} to the corresponding predefined values.
Signed-off-by: Alexander Bulekov <alxndr@bu.edu>
