SHADE is a fast SPARC instruction set simulator that is used to
perform a variety of analysis functions on SPARC executables. Shade
works by rewriting the executable with instrumentation and executing
natively on the hardware. For simple analysis operations such as
obtaining a dynamic instruction count the slowdown is just ~5x over
normal execution. This package includes a Shade binary, and a suite of
analyzers including ones to obtain a dynamic instruction count (icount),
to get a histogram of execution frequencies of different SPARC
instructions (ifreq), to get cache miss rates for a specified cache
configuration (cachesim5) and others. Shade also allows users to write
their own custom analyzers, and provides an API for that purpose. The
API is documented in doc/shade_user.pdf, but see also examples under
eg/ . The package also includes MPshade which can perform analysis on
multiprocess applications.
Solaris 9 Version
This version of Shade does not run on Solaris 10.
Solaris 10 discontinued support for some elements of the _lwp_
interface (e.g. _lwp_create and _lwp_wait) that has been deprecated for
many years, and was never a recommended interface. Shade V6, developed
8 years back, makes extensive use of the _lwp_ interface to support
threads in simulated applications, and doesn't compile or run on
Solaris 10.
This version supports multi-threaded applications. It does not run on Solaris 10.
Solaris 10 Version
This version only supports single-threaded applications on the Solaris 10 platform.
