Shade

Shade combines efficient instruction-set simulation with a flexible, extensible trace generation capability. Efficiency is achieved by dynamically compiling and caching code to simulate and trace the application program; the cost is as low as two instructions per simulated instruction. The user may control the extent of tracing in various ways; arbitrarily detailed application state information may be collected during the simulation, but tracing less translates directly into greater efficiency. Current Shade implementations run on SPARC systems and simulate the SPARC (Versions 8 and 9) and MIPS I instruction sets.
