Table 25 Information in Per-Source-File fcover Measurement Reports
DescriptionColumn
“Yes” or “No” indication of whether the named function was ever executed.Reached
Name of the function. The load module, main executable or shared library, containing
the function precedes the function name and is separated from it by “::”.
Function
Base source file name, without path information, and starting line number of the named
function. The tilde (“~”) precedes line numbers when they are approximate due to
optimization.
Source File [Line]
Unknown Source Files
If the source file information for a function has been stripped, which is often done with system
libraries, then HP Caliper reports on those functions separately. The report shows an additional
line in the Source Directory Summary and Source File Summary tables for Unknown Source Files
and the Totals coverage statistic includes them.
At the end of the per-source-file function coverage tables is an optional table for Unknown Source
Files. To generate this table, use unknown in addition to the other -r option settings.
-r for Function Coverage Reports
-r [module][:directory][:file][:function][:unknown][none][all]
Default value is module:directory:file:function:unknown.
module Shows data by load module.
directory Groups data by source directory.
file Generates Summary Report by source file.
function Shows function level detail by source file.
unknown When used together with the other report options, provides additional information
about functions from unknown source files in the summary and detail coverage
reports.
fprof Measurement Report Description
With the fprof measurement, produced by the fprof measurement configuration file, HP Caliper
measures and reports sampled instruction pointers (IPs). The fprof measurement samples the
instruction pointer (IP) at a regular interval (that is, at a particular number of CPU cycles). This
provides a statistical identification of where CPU events are occurring.
