Mishegos evaluates XED as one of its fuzzing worker targets.

SiliFuzz ← uses 100% 2e

SiliFuzz fuzzes XED as a proxy to generate instruction sequences for testing CPUs.

XED is an x86_64 instruction encoder/decoder that implements x86_64 instruction encoding and decoding.

The XED libFuzzer integration directly calls XED decode functions to fuzz the decoder.
