[PATCH 0/4] improve crash case minimization

Posted by Qiuhao Li 4 years, 11 months ago

Extend and refine the crash case minimization process.

I forgot to cc some reviewers in the last patch, so I merge it as the
first on in this patch series.

Qiuhao Li (4):
  fuzz: refine crash detection mechanism
  fuzz: split QTest writes from the rightmost byte
  fuzz: setting bits in operand of out/write to zero
  fuzz: delay IO until they can't trigger the crash
