pixstats(1) — Commands
NAME
pixstats − analyze program execution
SYNOPSIS
pixstats program [ options ]
DESCRIPTION
The pixstats program analyzes a program’s execution characteristics. To use pixstats, first use pixie(1) to translate and instrument the executable object module for the program. Next, execute the translation on an appropriate input. This produces a .Counts file. Finally, use pixstats to generate a detailed report on opcode frequencies, interlocks, a mini-profile, and more.
FLAGS
The pixstats command accepts the following options:
−cycle ns
Assume a ns cycle time when converting cycle counts to seconds.
−clockAssume 1000/ns cycle time when converting counts to seconds.
−disassemble
Disassemble and show the analyzed object code.
−dislimit f
Limit the disassembly to blocks with f% frequency.
−nocounts
Use 1 for each basic block count.
RESTRICTIONS
The pixstats program models execution assuming a perfect memory system. Memory system events such as cache misses will increase execution above the pixstats predictions.
