Where:
N Number of traces in the measurement.
mean Average number of states in the range per trace.
S
sumq
Sum of squares of states in the range per trace.
Symbols within range Names of other symbols that identify addresses or ranges
of addresses within the range of this symbol.
Additional symbols
for address Names of other symbols that also identify this address.
Some compilers emit more than one symbol for certain
addresses. For example, a compiler may emit
"math_library" and "_math_library" for the first address in
a routine named math_library. The analyzer will show the
first symbol it finds to represent a range of addresses, or a
single address point, and it will show the other symbols
under either "Symbols within range" or "Additional
symbols for address", as applicable. In the "math_library"
example, it may show either "math_library" or
"_math_library" to represent the range, depending on
which symbol it finds first. The other symbol will be
shown below "Symbols within range" in the report. These
conditions appear particularly in default measurements that
include all global and local symbols.
Relative and absolute
counts Relative count is the total number of states associated with
the address ranges in the performance measurement.
Relative time is the total amount of time associated with
the address ranges in the performance measurement. The
absolute counts are the number of states or amount of time
associated with all the states in all the traces.
