Hence, you can use AFL as usual. +To enable the passes you must set environment variables before you +compile the target project. + +The following options exist: + +export LAF_SPLIT_SWITCHES=1 Enables the split-switches pass. + +export LAF_TRANSFORM_COMPARES=1 Enables the transform-compares pass + (strcmp, memcmp, strncmp, strcasecmp, strncasecmp). + +export LAF_SPLIT_COMPARES=1 Enables the split-compares pass. + By default it will split all compares with a bit width <= 64 bits. + You can change this behaviour by setting + export LAF_SPLIT_COMPARES_BITW=<bit_width>. + |
