3.7.2 Profile Data Decoder

The code generation tools include a tool called the Profile Data Decoder or pdd430, which is used for post processing profile data (PDAT) files. The pdd430 tool generates a profile feedback (PRF) file. See Section 3.7.1 for a discussion of where pdd430 fits in the profiling flow. The pdd430 tool is invoked with this syntax:

pdd430 -eexec.out -oapplication.prffilename.pdat

-a	Computes the average of the data values in the data sets instead of accumulating data values
-eexec.out	Specifies exec.out is the name of the application executable.
-oapplication.prf	Specifies application.prf is the formatted profile feedback file that is used as the argument to --use_profile_info during recompilation. If no output file is specified, the default output filename is pprofout.prf.
filename.pdat	Is the name of the profile data file generated by the run-time-support function. This is the default name and it can be overridden by using the host environment variable TI_PROFDATA.

The run-time-support function and pdd430 append to their respective output files and do not overwrite them. This enables collection of data sets from multiple runs of the application.

NOTE

Profile Data Decoder Requirements

Your application must be compiled with at least DWARF debug support to enable feedback directed optimization. When compiling for feedback directed optimization, the pdd430 tool relies on basic debug information about each function in generating the formatted .prf file.

The pprofout.pdat file generated by the run-time support is a raw data file of a fixed format understood only by pdd430. You should not modify this file in any way.
