sandsifter - 1.03-2 main

The sandsifter audits x86 processors for hidden instructions and
hardware bugs, by systematically generating machine code to search
through a processor's instruction set, and monitoring execution for
anomalies. Sandsifter has uncovered secret processor instructions from
every major vendor; ubiquitous software bugs in disassemblers,
assemblers, and emulators; flaws in enterprise hypervisors; and both
benign and security-critical hardware bugs in x86 chips.
.
With the multitude of x86 processors in existence, the goal of the
tool is to enable users to check their own systems for hidden
instructions and bugs.
