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 Profile Guided Optimization (PGO)(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.

◦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
