pixstats(1) — RISC
Name
pixstats − analyze program execution
Syntax
pixstats program [ options ]
Description
The pixstats command analyzes a program’s execution characteristics. To use pixstats , invoke the pixie() command to translate and instrument the executable object module for the program. Then execute the translation on an appropriate input. This produces a .Counts file. You can then use pixstats to generate a detailed report on opcode frequencies, interlocks, a mini-profile, and more.
Options
−cycle ns Assume a ns cycle time when converting cycle counts to seconds.
−r2010 Use r2010 floating point chip operation times and overlap rules. This is the default.
−disassemble Disassemble and show the analyzed object code.
Restrictions
The pixstats command models execution assuming a perfect memory system. Cache misses, and so on, increase execution above the pixstats predictions.
