In this table, “program object” refers to any of the following:
• Thread
• Load module
• Function
• Source statement
• Instruction bundle

Percent of the total IP samples attributable to a given program object.% Total IP Samples
(ETB)
Running sum of the percent of total IP samples accounted for by the given program
object and those listed above it.

The average number of cycles elapsed to retire the bundle. If there are no stalls, it
should take exactly one cycle to retire a bundle. If the Cycles Per Bundle information
is more than 1, this means that many additional cycles of stall were seen on that
bundle.
If the Cycles per Bundle information is prefixed with an asterisk (*), that means
that instructions from that bundle are split issued.
Cycles Per Bundle
The column contains one of these:
• A source-code line number for rows showing statements
• An instruction slot number for rows showing instructions not on a bundle
boundary
• A source-code column number followed by an offset from the beginning address
of a function for rows showing instructions on a bundle boundary
Column and line numbers are preceded by “~” when they are approximate due to
optimization.

The column contains either a source statement preceded by “>” or a disassembled
instruction. Statements that are out of order due to optimization are preceded by
“*>”.
