# qemu_tmin

QEMU testcase minimizer.

This folder contains an example fuzzer which runs each entry in the input corpus
and minimizes the input, ensuring that coverage map remains the same. The output
is a new corpus that may or may not be smaller than the original inputs, but
will not be larger.

If some input files are idential, only one of each duplicate set will be kept
for minimization.

The following architectures are supported:
* arm
* aarch64
* i386
* x86_64
* mips
* ppc
