Building & running the fuzz target: Android device

It is recommended to set rss limit to higher values (such as 4096) when running the fuzzer to avoid frequent OOM libFuzzer crashes.

$ source build/envsetup.sh
$ lunch aosp_arm64-eng
$ SANITIZE_TARGET=hwaddress make dng_parser_fuzzer
$ adb sync data
$ adb shell /data/fuzz/arm64/dng_parser_fuzzer/dng_parser_fuzzer \
$ -rss_limit=4096 \
$ /data/fuzz/arm64/dng_parser_fuzzer/corpus

Building & running the fuzz target: Host

$ source build/envsetup.sh
$ lunch aosp_x86_64-eng
$ SANITIZE_HOST=address make dng_parser_fuzzer
$ LD_LIBRARY_PATH=$ANDROID_HOST_OUT/fuzz/x86_64/lib/ \
$ $ANDROID_HOST_OUT/fuzz/x86_64/dng_parser_fuzzer/dng_parser_fuzzer \
$ -rss_limit_mb=4096 \
