Code CoverageCode Coverage
◦ Available with COBOL, pTAL, and C/C++
compilers on Integrity NonStop servers
◦ Creates instrumented object files containing
extra code
◦ Records which functions and blocks are
executed
◦ Records how many times each is executed
◦ The code coverage report is a set of HTML
files viewable with any standard HTML
browser

Profile Guided Optimization (PGO)Profile Guided Optimization (PGO)
◦ pTAL and C/C++ compilers only
 Incorporate profiling information from program
execution into optimization
 Level 2 optimization only

ApplicabilityApplicability
◦ Can be used with:
 OSS processes
 Guardian processes
 Active and passive process pairs
 Mixed language processes
 Processes with embedded NonStop SQL/MP or
NonStop SQL/MX

UseUse
◦ No source code changes are needed to
instrument an application.
◦ Changes are in the commands used to
compile and link the application
 Separate compiler directives for Code Coverage
and for Profile Guided Optimization
◦ You may instrument only a subset of your
application
 specify the compiler options for only that subset of
your source files.

Installing the Code Cover UtilityInstalling the Code Cover Utility
◦ Program codecov runs on a Windows
workstation
◦ codecov:
 Copy $SYSTEM.ZCODECOV.T0746SET to
workstation
 Change the name to setup.exe
 Run setup.exe
 Creates Program FilesHewlett-
PackardCodeCoveragecodecov.exe
◦ Add
Program FilesHewlett-PackardCodeCoverage to PATH

Building an ApplicationBuilding an Application
for Code Coveragefor Code Coverage
◦ Compiler option:
 Guardian: CODECOV
 OSS: –Wcodecov
 Windows:
 c89, ecobol: –Wcodecov
 eptal: –codecov
◦ Creates or updates the Static Profiling
Information (SPI) file:
 Guardian: PGOSPI, code 180
 OSS/Windows: pgopti.spi
◦ If link editing manually:
 Use –l pgo to reference the pgodll library

Running the ApplicationRunning the Application
◦ Execute as normal
◦ Process creates a new raw data file for each
execution:
 Guardian: ZZPFxxxx, code 180, in current default
subvolume
 OSS: ZZPFxxxx.dyn in current working directory
◦ Creates ZZPELOG if any errors during
execution
