.GCDA File

The gcda file extension is mainly related to GCC (GNU Compiler Collection) software and used for files generated by the gcov program during profilling.

The gcda file is generated when a program containing object files built with the GCC -fprofile-arcs option is executed. 

The separate gcda file is created for each object file compiled with this option. It contains arc transition counts, and some summary information.
