+# laf-intel instrumentation
+
+## Usage
+
+By default the passes will not run when you compile programs using 
+afl-clang-fast. 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 AFL_LLVM_LAF_SPLIT_SWITCHES=1`
+
+Enables the split-switches pass.
+
+`export AFL_LLVM_LAF_TRANSFORM_COMPARES=1`
+
+Enables the transform-compares pass (strcmp, memcmp, strncmp, strcasecmp, strncasecmp).
+
+`export AFL_LLVM_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 AFL_LLVM_LAF_SPLIT_COMPARES_BITW=<bit_width>`.
