alexcrichton opened PR #10612 from alexcrichton:log-module-dna to bytecodealliance:main:

This commit updates the fuzzing infrastructure of the wasmtime-fuzzing crate to record the "DNA string" of a module used to generate a module in a *.dna file. This is accompanied with a *.json file to pass to wasm-tools smith --config. The end result is that it should be possible now to more easily reproduce a module generation outside of Wasmtime itself when reproducing bugs and such.

Creation of these files is gated on the debug log level in a similar manner to creation of normal wasm files is gated on the debug log level too.
