Data Supporting Instrumentation Implementation
There are two important arrays of type “unsigned char,” named “
gba_states
” and “gba_acts
” in “glob_dat
.c
”. The “gba_states
” array will hold 1 bit per each state in the application. The “gba_acts
” array will hold 2 bits per each activity in the application. Those bits are packed together into the 8 bits (char) chunks.
