Subject: [PATCH 0/8] Fuzzing misc bugfix and performance improvements
Date: Mon, 20 Mar 2017 11:19:37 +0000 [thread overview]
Message-ID: <1490008785-6058-1-git-send-email-andrew.cooper3@citrix.com> (raw)
This series is a couple of bugfixes, but is mainly a set of performance
improvements to using the AFL test harness. This series increases the
performance as reported by afl-fuzz from 6k execs/s to 38k execs/s, or more
than 6 times faster.
Andrew Cooper (8):
tools/fuzz: Remove .d files in clean
tools/fuzz: Use $(CC) for linking the harnesses
tools/fuzz: Include LLVMFuzzerTestOneInput() in the generated .a
tools/insn-fuzz: Use shorter filenames
tools/insn-fuzz: Use getopt() for parsing the command line
tools/insn-fuzz: Accept fuzzing input on stdin
tools/insn-fuzz: Make use of LLVMFuzzerInitialize()
tools/insn-fuzz: Support AFL's afl-clang-fast mode
