.SH Name
pixstats \- analyze program execution
.SH Syntax
.B pixstats
program [ options ]
.br
.SH Description
The
.B pixstats
command analyzes a program's execution characteristics.
To use
.B pixstats ,
invoke the
.MS pixie 1
command to translate and instrument the executable object module for the
program.  Then execute the translation on an appropriate input.  This
produces a
.I .Counts
file.  You can then use 
.B pixstats
to generate a detailed report on opcode frequencies, interlocks, a
mini-profile, and more.
.SH Options
.TP 15
.B \-cycle \fIns
Assume a
.I ns
cycle time when converting cycle counts to seconds.
.TP 15
.B \-r2010
Use r2010 floating point chip operation times and overlap rules.  This
is the default.
.TP 15
.B \-disassemble
Disassemble and show the analyzed object code.
.SH Restrictions
The 
.B pixstats
command models execution assuming a perfect memory system.
Cache misses, and so on, increase execution above the 
.B pixstats
predictions.
