A very curious little minx

1. Instrumentation framework for building dynamic analysis tools
2. Valgrind vs Sanitisers:
   • Works on binaries (sanitisers require source)
   • Works via interpretation vs instrumentation
   • Can detect more bugs with compile time instrumentation
   • Valgrind is more monolithic, while sanitisers are more specialised
   • Much slower than sanitisers
   • Some sanitisers cannot be combined (ASan + MSan == memcheck)
3. Includes 6 prod-quality tools:
   • Memory error detector
   • Two thread error detector
   • Cache profiler
   • Branch predictor profiler
   • Call-graph generating cache
   • Heap profiler
4. Three experimental tools:
   • Stack/global array overrun detector
   • Heap profiler that examines how the heap blocks are used
   • SimPoint basic block vector generator
