This is a simple patch to AFL to make other-arch (non-x86 based) support easy. Just run ./build.sh <arches> to get started, where <arches> can be one or more of:

   aarch64 alpha arm armeb cris i386 m68k microblaze microblazeel 
   mips mips64 mips64el mipsel mipsn32 mipsn32el or32 ppc ppc64 
   ppc64abi32 ppc64le s390x sh4 sh4eb sparc sparc32plus sparc64 unicore32 
   x86_64

This will compile AFL with qemu support for the architecture requested.

Once building is completed, you'll need to set some environment variables before you can begin fuzzing.

Set QEMU_LD_PREFIX to a path containing a directory lib which itself contains the shared objects required by the binary (such as libc compiled for <arch>)

export QEMU_LD_PREFIX=. # assuming your CWD contains the 'lib' directory

Set AFL_PATH to the directory containing the afl-qemu-trace binary for the architecture of the binary being fuzzed

export AFL_PATH=afl-other-arch/tracers/$TARGET/

Happy other-arch fuzzing!
