-## Usage
-
-By default these 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 
-1. simplify operators >= (and <=) into chains of > (<) and == comparisons
-2. change signed integer comparisons to a chain of sign-only comparison
-and unsigned comparisons
-3. split all unsigned integer comparisons with bit widths of
-64, 32 or 16 bits to chains of 8 bits comparisons.
-
-You can change the behaviour of the last step by setting
-`export AFL_LLVM_LAF_SPLIT_COMPARES_BITW=<bit_width>`, where 
-bit_width may be 64, 32 or 16.
-
-A new experimental feature is splitting floating point comparisons into a
-series of sign, exponent and mantissa comparisons followed by splitting each
-of them into 8 bit comparisons when necessary.
-It is activated with the `AFL_LLVM_LAF_SPLIT_FLOATS` setting.
-Note that setting this automatically activates `AFL_LLVM_LAF_SPLIT_COMPARES`
-
-You can also set `AFL_LLVM_LAF_ALL` and have all of the above enabled :-)
